Nowadays, the extraction of its own electricity is not such an unusual thing. The power grids work with interruptions, especially outside major cities. And to avoid these problems, many are resorted to the use of electric generators. In order to acquire or make such a need to learn about the best electrical generators that can be made with your own hands.

What it is

An electric generator is a special device that is intended for conversion and impression of electricity. And it is usually mined from unusual sources - from gasoline and gas to eco-friendly, sort of wind, sun and water. Such a generator can cost expensive. Even the most low-power can cost from 15,000 rubles.

Therefore, in order to save several tens of thousands, many create them themselves. It is good that ideas, how to make an electric generator with your own hands, is now quite a lot.

Principle of operation

Electromagnetic induction underlies the principle of operation of the electric generator.

Created an artificial magnetic field. Through it passes a conductor creating a pulse. The pulse of meanwhile becomes a constant current.

In the generator itself there is an engine that is capable of producing electricity through fuel combustion of a certain type. It can be diesel fuel, gasoline, gas.

At this time, fuel falling into the place of burning produces gas in the process of burning. And gas makes the crankshaft rotate. In turn, gives the impetus to the slave shaft. The latter provides energy at the output in certain quantities.

Electrically generators are based on two mandatory mechanism - the rotor and the stator. Their presence from fuel and power does not depend.

The rotor is needed to create the same electromagnetic field. It is based on magnets that are at the same distance from the core.

The stator does not move. This allows you to force the rotor to move until the stator adjusts the electromagnetic field. It is achieved due to steel blocks in its device.

Asynchronous

Types of electrical generator devices do not end in separation to use fuel. Also, by the type of rotation of the rotor, the generators can be:

• Simultaneous - more difficult in its design. Voltage drops lead to faults. This affects work and productivity.
• Asynchronous - with a slight principle of work, other technical characteristics.

Magnetic coils on the synchronous generator rotor make it difficult to move the rotor. The rotor in the asynchronous generator is more like a flywheel.

Features of the design have a great influence on the efficiency. Simultaneous loss up to 11%. Asynchronous loss maximizes 5%. Such indicators make asynchronous devices are popular not only in everyday life, but also in production.

Asynchronous generators have more advantages:

• Frequent repair is not needed, because the simple body reliably protects the engine from spent fuel and excess moisture.
• Rectifier at the output will protect the electrical appliances feed on the generator.
• Resistance to voltage drops.
• All parts in the design are quite reliable and durable, so operation without repair can last more than 15 years.
• Due to the resistance to differentials and the ability to feed instruments with an ohmic load, the number of different devices for the connection is growing - from computers to welding machines and lamps.
• High efficiency.

What materials are needed

To collect a small asynchronous generator, it will be useful to such details as:

• Engine. It is easiest to take out the facilitated electrical appliances, because it is difficult to do it with your own hands and for a long time. Engines from washing machines will be especially good.
• Stator. You need to take ready, with winding.
• Transformer or rectifier. It is useful if the outlet electricity has different power.
• Electric wires.
• Insulating tape.

Of course, to make chickenpox and solar generators with their own hands, more complex schemes and more materials, but if desired, and their instructions can be found.

Note!

Assembly

The assembly process may be complicated for various reasons. For example, there is no definite skill for work. There is no experience in creating such devices. No desired parts and spare parts. However, if all this and a great desire in stock, then you can try.

But before starting work, you must fulfill several conditions - mined materials and instructions for the manufacture of an electric generator. And read them. And also take care of safety.

Before starting work, it makes sense to take care of the assembly and drawings. This will greatly facilitate and speed up the process.

Gas and gasoline electric generators are harvested most often. But both when they are assembled and when assembling others, you need to prepare and some calculations. For example, it is important to know the power of the desired generator.

To determine the speed of rotation, the engine must be connected to the network. To determine the tachometer will be required. The value obtained during measurements must be added to the compensatory value of 10%. This value allows not to give the engine to overheat.

Note!

Considering the power you need to choose condensers.

It is important to remember the ground, because it goes about working with electricity. And this is not only a matter of depreciation of the device, but also a security issue.

The assembly itself is simple - condensers are connected to the engine in turn according to the scheme (it can be found on the Internet). It's all that is needed to create a low-power generator.

This option is the most comfortable and easy. However, it is worth paying attention to the following points:

• It is necessary to monitor the engine temperature so that it does not overheat.
• Sometimes the generator will need to give up to 40 degrees.
• The efficiency may have to decline depending on the time of operation. This is normal.
• The user will need to independently follow the state of the generator, connect the measuring instruments to it.

After assembly, the mechanical part should do the electrical side. Starting standing after installing the pulleys connected by the belt.

• Winding on an electric motor connected according to the star scheme.
• Capacitors connected to the winding must form a triangle.
• Voltage will be removed between the end of the winding and midpoint. Then the current with a voltage of 220 volts is obtained, and between the windings - 380 volts.

Note!

Experts give some more useful tips to help when assembling the generator:

• Electric engine can be very hot. That this is not - it is necessary to replace the capacitors on those who have less capacity.
• Homemade electric generators usually assume capacitors with voltage from 400 volts. It is enough for the right job one.
• The network needs a three-phase transformer if all phases of the engine are needed to power the house.

Most likely, even made, like on beautiful photos, a homemade electric generator, will not be able to compete with purchased models.

However, if you perceive it as an additional, a spare source of electricity, it can well be done and used. Moreover, as practice shows, it is not so difficult to make the generator. You just need to attach efforts and everything will turn out.

Photo of electric generators do it yourself

The generator is a device that produces products producing electrical energy or converting it to another. What is the device, how to make a generator, what is the principle of its work, what is the difference from the synchronous generator? Tell me further.

The generator is called an electric machine, which is engaged in the transformation of mechanical energy into current electricity. In most cases, the rotational type of magnetic field is used for this. The device is made of a relay rotating inductor, contact rings, a terminal, a sliding brush, a diode bridge, diodes, a toxal ring, stator, rotor, bearings, a rotary shaft, pulley, impeller and anterior cover. Often, the design includes a turn with an electromagnet that produces energy production.

Generator do it yourself

It is important to note that the generator is AC and DC. In the first case, vortex currents are not formed, the apparatus can work under extreme conditions and has a reduced weight. In the second case, the generator does not need elevated attention and has a greater amount of resources.

The alternator is synchronous and asynchronous. The first is an aggregate that works as a generator, where the number of rotational rotations of the stator is equal to the Rotor. The rotor forms a magnetic field and creates in the EMF stator.

Note!As a result, a constant electric magnet is created. Of the advantages, the high stability of the created voltage is noted, from the disadvantages - current overload, since with an overestimated load, the regulator increases the current in the rotor winding.

Synchronous device

The asynchronous apparatus consists of a short-circuited rotor and exactly the same stator as the previous model. At the time of rotation of the rotor, an asynchronous generator induces electrical strokes and a magnetic field creates a sinusoidal voltage. Since it does not have connection to the rotor, then the possibility is to artificially adjust the voltage and current, no. These parameters vary under the electrical load on the starting winding.

Device asynchronous machine

Operating principle

Any generator acts according to the electromagnetic inductive law, due to the tip of the electric flow in the closed frame with the intersection of the rotating magnetic field created by the help of permanent magnets or windings. The electromotive force enters the closed circuit from the collector and the brush node along with the magnetic flux, the rotor rotates and produces voltage. Due to spring-loaded brushes, which are pressed against the plate collectors, transmitted electricals to the output terminals. Further, it goes to the user's network and applies to electrical equipment.

Principle of operation

Difference from a synchronous generator

The synchronous gasoline generator is not overloaded due to transient modes that are associated with a start-up load from the consumers of this power. It is a source of reactive power, while asynchronous consumes it. The first is not afraid of overloads when the mode is set thanks to the control system through the connection, which is inverse the voltage current in the wire. The second has an unregulated artificial force of the clutch of an electromagnetic rotary field.

Note! It is important to understand that asynchronous variety is more popular thanks to a simple design, unpretentiousness, lack of need in technical qualified maintenance and comparative cheapness. It is raised when: there are no high requirements for frequency with voltage; It is planned to work as an aggregate in abed place; There is no possibility to overpay for another variety.

Application area

AC generator is a multifunctional device, due to which energy can be transmitted over long distances and at the same time it is quickly redistributed. In addition, it turns into light, thermal, mechanical and other energy according to the instructions. Easy to manufacture. Therefore, the scope of their use is extensive. Today, such devices are used everywhere: both in industry and in terms of life. They equip the powerful motor.

For example, the electro and the wind generator will be useful at the time when the volt network is turned off, an accident will occur at the power plant, there will be an additional energy in the engine.

The gasoline and magnetic generator, due to low weight and compactness, can be transported and used in agriculture, in the country, in the forest. It will serve as a quick response and will help create emergency lighting.

Application area

Classification of the device

The classification of the device is extensive. Today it is asynchronous and synchronous, with a fixed rotor or a stator, single-phase, two-phase and three-phase, with independent or independent excitation, with excitation windings or excitation from a permanent magnet.

Note! It is worth noting that at the moment three-phase models are more popular with a rotating circular magnetic field, system equilibrium, work in several modes and high efficiency coefficients.

Classification of equipment

Device assembly scheme

Collect electric generators on 220 with their own hands by analogy with the production model. For this, you may need video tutorials or textbooks. Then you need to properly connect all the instruments of one system. You can do this by a star or triangle scheme.

In the first case, the electrical connection occurs for all ends of the windings of one point, and in the second case, a sequential type of winding generator connections is provided. It is important to note that these schemes can be used only if the phase load is uniform. Then the topic, how to make a generator at home will be relevant.

Star Connection Scheme

In general, the generator is called a device that converts mechanical energy into electrical with a wire variety of a magnetic field coil. By the number of phases, aggregates are with one, two and three phases.

Connection diagram Triangle

You can make it today with your own hands using the special scheme indicated above.

It is difficult not to note how much the stability of electricity supply to country objects differs from the provision of urban buildings and electricity enterprises. Admit that you as an owner of a private house or giving more than once came across interruptions associated with them inconveniences and damaging technology.

Listed negative situations together with the consequences will cease to complicate the life of natural expanses. Moreover, with minimal labor and financial costs. To do this, you just need to make a windmatch generator of electricity, which we tell in detail in the article.

We described in detail the options for manufacturing useful in the economy of a system that saves energy dependence. According to our advice, to build the wind generator with their own hands will be able to an inexperienced homemade master. The practical device will help significantly reduce daily expenses.

Alternative energy sources - the dream of any dacket or homeowner, whose plot is located away from central networks. However, receiving electricity bills spent in the urban apartment, and looking at the increased tariffs, we realize that the wind generator, created for household needs, we would not prevent us.

After reading this article, you may realize your dream to reality.

The wind generator is an excellent solution to provide a rustic electricity object. And in some cases, its installation is the only possible way out.

In order not to spend in vain money, strength and time, let's define: Are there any external circumstances that will create obstacles in the process of exploitation of the wind generator?

To ensure the electricity of cottage or a small cottage, the power of which will not exceed 1 kW. Such devices in Russia are equated to household products. Their installation does not require certificates, permissions or any additional coordination.

Unfortunately, often power supplying organizations do not cope with the provision of private householdings of electricity. Due to electricity interruptions, the owners of cottages and country cottages are forced to turn to alternative sources of electricity. The most common one is the generator.

Features of the electric generator and the area of \u200b\u200bits use

The electric generator is called a mobile device that serves to transform and accumulate electricity. The principle of operation of this device is low, which allows you to make it own. A simple generator schema can be easily found on the Internet.

The unit, made by hand, will not be a worthy competitor to the product assembled at the factory, but this is the best solution if you want to save a significant amount of money.

Electrical generators have a fairly wide range of applications. As can be seen in the photo of homemade generators, they can be used in wind power plants, in welding works, as well as as an autonomous device to support electricity in private homes.

The inclusion of the generator is carried out in the incoming voltage. For this, the device is connected to a power source, but this is not rational for a mini-power station, because it is obliged to produce an electric current, and not spend it to run.

As a result, models are particularly popular, equipped with the ability to sequentially switch capacitors or self-excitation feature.

Nuances that need to know to create an electric generator

The generator purchases will cost quite expensive. Therefore, more and more devils are resorted to the manufacture of the aggregate with their own hands. The simplicity of the principle of operation and the construction solution allows you to assemble the electric generating device in just a couple of hours.

How to make a generator with your hands?

The first stage is the setting of all equipment in such a way that the rotational speed exceeds the speed of the electric motor. Measuring the magnitude of the rotation of the motor, add another 10%. You will receive the speed with which the electric generator should work.

Step second - alteration of the generator under itself with the help of capacitors. It is very important to correctly determine the required container.

The third step is to install capacitors. Here it is necessary to strictly follow the calculation. In addition, you need to make sure the insulation. That's all - the generator assembly is completed.

Master class on the manufacture of an asynchronous type generator

One of the most common types of self-made generators is an asynchronous electric generator. This is explained by his simple principle of work and good technical techniques.

What is needed for the manufacture of such a generator with your own hands? First of all, you will need an asynchronous engine. Its distinctive feature are short-circuited turns instead of a magnet on the rotor. You will also need condensers.

Instructions for manufacture

Connect a voltmeter to any of the engine windings, and we will be promoting the shaft. The voltmeter will show the presence of a voltage that is taken due to the residual rotor magnetization.

This is not a generator. Let's try to create a magnetic field with rotary turns. When the electric motor is turned on, the magnetization of the short-circuited rotor turns occurs. A similar result can also be obtained during the operation of the device in the "Generator" mode.

We put the shunt on one of the stator windings using a non-electrical capacitor. We will spin shaft. The value of the voltage that appears with the time will become equal to the nominal engine voltage. Next, it is chemmed with the help of a capacitor, the remaining windings of the power device and connect them.

The generator is considered a potentially dangerous device, because the appeal to it requires special accuracy. It should be protected from atmospheric precipitation and mechanical shocks. It is best to make a special casing.

If the device is autonomous, it should be equipped with sensors and instruments to fix the required data. It is also desirable to equip the device to turn on / off.

With the slightest doubts in their abilities it is better to abandon the independent manufacture of the generator.

How to make the electric generator with your own hands, disassemble in detail

The constant and uninterrupted security of electricity in the house is a pledge of a pleasant and comfortable pastime at any time of the year. To organize autonomous food of the country site, we will have to resort to mobile installations - electrical generators, which in recent years are especially popular due to the large range of various capacities.

Scope of application

Many are interested in how to make an electric generator for the country area? We will tell about it below. Apply in most cases an asynchronous alternator of AC, which will produce energy to work electrical appliances. In an asynchronous generator, the rotation speed of rotors than in synchronous and efficiency will be higher.

However, the power plants found their use in a wider circle, as an excellent means for energy production, namely:

• They are used on wind power plants.
• Used as welding units.
• Provide autonomous support for electricity in the house on a par with a miniature hydroelectric station.

The unit is turned on using an incoming voltage. Often, for the startup, the device is connected to the power supply, but this is not a completely logical and rational solution for the mini station, which itself should produce electricity, and not consume it to start. Therefore, in recent years, generators with self-excitation or consistent switching of capacitors are actively produced.

How the electric generator works

Asynchronous generator of electricity produces a resource if the motor rotation speed is faster than synchronous. The most ordinary generator works on parameters from 1500 revolutions.

It produces energy if the rotor works faster, rather than synchronous speed. The difference between these indicators is called sliding and calculated in the percentage ratio relative to synchronous speed. However, the speed of the stator is even higher than the rotor speed. Due to this, the flow of charged particles changing polarity is formed.

We watch the video, the principle of operation:

When excited, the connected device of the electric generator takes control over the synchronous speed, independently controlling the slide. The emerging of the stator energy passes through the Rothor, however, the active meal has already moved to the coil of the stator.

The main principle of the operation of the electric generator is reduced to the transformation of mechanical energy into electrical. To launch a rotor for generating energy, a strong torque is needed. The most adequate option, according to Electricians, is the "perpetual course of a combat", which supports one rotation speed over the operation time of the generator.

Why an asynchronous generator is used

Unlike a synchronous generator, asynchronous has a huge amount of advantages and advantages. The main factor in the choice of an asynchronous version was the low clearing. The high clearing indicator characterizes the quantitative presence of higher harmonics in the output voltage. They cause useless heating of the motor and uneven rotation. Synchronous generators have a clearing value at a level of 5-15%, in asynchronous it does not exceed 2%. These it follows that an asynchronous energy generator generates only useful energy.

A little about the asynchronous generator and its connection:

No less significant advantage of this type of electric generator is the complete absence of rotating windings and electronic parts sensitive to damage and external factors. Consequently, this type of devices is not subject to active wear and will serve longer.

How to make a generator with your own hands

Device asynchronous alternator

The acquisition of an asynchronous electric generator is sufficiently lack of pleasure for the average inheritant of our country. Therefore, many craftsmen resort to solving the issue of self-assembly of the device. The principle of operation, as well as the design - is quite simple. If you have all tools, the assembly does not take more than 1-2 hours.

According to the above principle of the electrical generator, all the equipment should be adjusted so that the rotations are faster than the engine turnover. To do this, you should connect the engine to the network and start it. To calculate the number of revolutions per minute, use a tachometer or tachogenerator.

By defining the value of the engine rotation speed, add 10% to it. If the speed of rotation is 1500 revolutions per minute, then the generator should work for 1650 turns.

Now you need to remake the asynchronous generator "Under itself" using the capacitors of the necessary containers. To determine the type and capacity, use the following sign:

Table of capacity DL

We hope how to assemble the electric generator with your own hands is already clear, but pay attention: the capacitance of the capacitors should not be very high, otherwise the generator operating on diesel fuel will be warm.

Install capacitors according to the calculation. Installation requires sufficient attention. Ensure good isolation, use special coatings if necessary.

On the engine's database, the generator assembly process is completed. Now it can be used as a necessary source of energy. Remember that in the case when the device has a short-circuit rotor and produces a fairly serious voltage that exceeds 220 volts, it is necessary to install a lowering transformer that stabilizes the voltage at the required level. Remember that all devices in the house work should be strict control of the self-made electric generator by 220 volts by voltage.

We watch the video, stages of work:

For a generator that will work on low capacity, in order to save items, you can use asynchronous motors with one phase from old or unnecessary household electrical appliances, such as washing machines, drainage pumps, lawn mowers, chainsaws, etc. Motors from such household appliances should be connected in parallel winding. Alternatively, you can use capacitors shifting phases. They rarely differ at the necessary power, so it will be necessary to increase it to the required indicators.

Such generators show themselves very well with the need to supply light bulbs, modems and other small devices with a stable active voltage. With certain knowledge, you can connect an electric generator to a power supply or heater.

A ready-to-use generator should be installed so that precipitation and the environment do not affect it. Take care of the additional casing that will protect the installation from adverse conditions.

Almost every asynchronous generator, whether it is brushless, electric, gasoline or diesel generator, it is considered a sufficiently high level of danger. Contact such equipment very carefully and keep always protected from external weather and mechanical impact or make a casing for it.

We look at the video, Specialist Specialist Tips:

Any autonomous unit should be equipped with special measuring instruments that will record and display data on performance efficiency. To do this, you can use a tachometer, voltmeter and frequency meter.

• Equip the generator with the on and off button as possible. You can use manual start to start.
• Some electrical generators are required to ground before use, carefully evaluate the territory and select a place to install.
• When transforming mechanical energy into electricity, sometimes useful coefficient can fall up to 30%.
• If not sure or is afraid to do anything wrong, we advise you to purchase a generator in the appropriate store. Sometimes risks can turn around extremely deplorable ...
• Follow the temperature of the asynchronous generator and its thermal regime.

RESULTS

Despite its simplicity of implementation, homemade electrical generators are a very painstaking work that requires complete concentration on the design and proper connection. It is advisable to build from a financial point of view only if you already have a workable and unnecessary engine. Otherwise, you will give for the main element of the installation more than half of its cost, and total spending can significantly exceed the market value of the generator.

Now you know how to make an electric generator and if you firmly decided to create it, we hope you received answers to all the questions you are interested in before starting the assembly and now with the full luggage of knowledge you can start work.

In conclusion, I wanted to offer you an assembly of a wonderful invention of one engineer student. This is weak, the generator who can save you in a difficult minute without waste of cash even on fuel.

Homemade generator. All ways do it yourself

Method 1.

On the Internet found an article on how to remake the car generator to the generator with permanent magnets. Is it possible to use this principle and remake the generator with your own hands from an asynchronous electric motor? It is possible that there will be large energy losses, not the location of the coils.

Asynchronous type, I have a 110 volt voltage, turns - 1450, 2.2 amps, single-phase. With the help of tanks, I do not take the homemade generator, as there will be large losses.

It is proposed to use simple engines according to such a scheme.

If you change the engine or generator with a rounded form magnets from speakers, then you need to install them in crabs? Crabs are two metal parts, anchored outside the excitation coils.

If the magnets wear on the shaft, the shaft will shunt the magnetic power lines. How will the excitement be? The coil is also located on the shaft of metal.

If you change the connection of the windings and make a parallel connection, dispersed to revolutions above normal values, then it turns out 70 volts. Where to get a mechanism for such revolutions? If you rewind it on the reduction of revolutions and below the power, then the power drops too.

An asynchronous type engine with a closed rotor is an iron that is polished by aluminum. You can take a homemade generator from the car, in which the voltage is 14 volts, the current is 80 amp. This is good data. The engine with a collector on alternating current from the vacuum cleaner or washing machine can be applied to the generator. Install the stator to establish a constant current voltage to shoot with brushes. By the greatest EDC change the angle of brushes. The efficiency is striving for zero. But, it is better than a synchronous type generator, not invented.

I decided to experience the homemade generator. Single-phase asynchronous motor from the baby's washing drill. I connected a capacity of 4 μF to it, it turned out 5 volts of 30 hertz and a current of 1.5 milliam per short circuit.

Not every electric motor can be used as a generator in this method. There are motors with a steel rotor, having a small degree of magnetization on the residue.

It is necessary to know the difference between the transformation of electrical energy and generation of energy. Convert 1 phase to 3 in several ways. One of them is mechanical energy. If the power station is disconnected from the outlet, then all transformation disappears.

Where does the movement of the wire with an increase in speed, clearly. From where the magnetic field will be to obtain EDC in the wire - it is not clear.

Explain it just. Because of the mechanism of magnetism, which remained, the EMF is formed in anchor. There is a current in the stator winding, which is closed on the tank.

The current arose, which means that it gives an increase in the electromotive force on the coils of the rotor shaft. The current current gives an increase in the electromotive force. Stator electrotox forms electromotive force much more. It goes until the equilibrium of stator magnetic streams and rotor, as well as additional losses.

The size of the capacitors is calculated in such a way that at the outputs, the voltage reaches the nominal value. If it is small, then reduce the container, then increase. There were doubts about old engines that are allegedly excited. After overclocking the rotor of the motor or generator, it is necessary to poke quickly to any phase with a small amount of volts. Everything will come to a normal state. Charge a capacitor to a voltage of equal half of the tank. Turning on with a switcher with three poles. This applies with a 3-phase motor. Such a scheme is used for passenger transport cars generators, as they have a short-circuited rotor.

Method 2

A homemade generator can be done differently. The stator has a tricky design (has a special design solution), it is possible to adjust the output voltage. I made a generator with my own hands of this kind on construction. The engine took 7 kW with a capacity of 900 revolutions. I connected an excitation winding by a triangle scheme to 220 V. launched it to 1600 revolutions, the capacitors were 3 to 120 μF. They included the contactor with three poles. The generator acted as a rectifier with three phases. From this rectifier, an electric drill was fed with a collector for 1000 watts, and a 2200 watt disc chopped, 220 V, Bulgarian 2000 watt.

I had to make a soft start system, another resistor with a short phase after 3 seconds.

For motors with collectors it is incorrect. If you increase the rotating frequency in two times, the container will decrease.

The frequency will also increase. The containers circuit turned off in automatic mode so as not to use the reactivity torus, do not spend fuel.

During operation, you need to click on the stator of the contactor. Three phases disassemble them by unnecessariness. The reason lies in a high gap and an enlarged scattering of the pole field.

Special mechanisms with a double cell for protein and oblique eyes for a protein. Still, I got from the Motorker washing 100 volts and the frequency of 30 hertz, the lamp on 15 watts does not want to burn. Very weak power. It is necessary to take a motor stronger, or more capacitors.

Under the wagons, a generator with a rotor is short-circuited. Its mechanism comes from the gearbox and on the belt transmission. Rotation speed 300 revolutions. It is like an additional load generator.

Method 3.

You can construct a homemade generator, a power station on gasoline.

Instead of a generator, use a 3-phase asynchronous motor for 1.5 kW per 900 revolutions. Italian electric motor, can be connected triangle and star. At first I put the engine on the base with the DC motor, attached to the coupling. Began to turn the engine at 1100 revolutions. A voltage 250 volts appeared on the phases. I connected a 1000 watt light bulb, the voltage immediately fell to 150 volts. Probably, it is from phase skew. For each phase, it is necessary to include a separate load. Three 300 watt bulbs will not be able to reduce the voltage up to 200 volts, theoretically. You can put a capacitor more.

Engine turnover must be done more, when loading does not reduce, then the nutrition network will be permanent.

Significant power is necessary, the autogenerator will not give such power. If you rewind a large KAMAZ, then 220 V will be released from it, since the magnetic core will be oversaturated. It was designed for 24 volts.

Today I was going to try to connect the load through a 3-phase power supply unit (rectifier). In the garages, the light turned off, failed. In the city of power engineers systematically turn off the light, so it is necessary to make a source of constant power to electricity. For electric welding there is a hitch, shaped to the tractor. To connect an electrical tool, a permanent voltage source is needed to 220.. There was a thought to construct the homemade generator with your own hands, and the inverter to it, but, on batteries, it is not long to work.

Recently included electricity. Connected an asynchronous engine from Italy. Put it with a motor chainsaws on the frame, twisted the shafts together, put the rubber clutch. The coils connected according to the stars scheme, triangle condensers, 15 μF. When the motors launched, it did not work at the power output. Attached the capacitor charged to phases, the voltage appeared. The engine issued its capacity of 1.5 kW. In this case, the supply voltage decreased to 240 volts, 255 volts were at idle. Schlifmashinka normally worked for 950 watts.

I tried to increase engine speed, but it fails. After contacting the capacitor with a phase, the voltage occurs immediately. I will try to put another engine.

What designs of systems abroad are made for power plants? On 1-phase it is clear that the rotor owns winding, no phase skew, because one phase. In 3-phase there is a system that gives power adjustment when connected to it with the highest load. You can still connect an inverter for welding.

On the weekend I wanted to make a homemade generator with my own hands with the connection of an asynchronous engine. A successful attempt to make a homemade generator was to connect an old engine with a cast iron case per 1 kW and 950 revolutions. The motor is excited normally, with one capacity of 40 μF. And I installed three containers and connected them with a star. It was enough to launch the electric drill, the grinder. I wanted to give out the issuance of voltage at the same phase. For this, the three diodes connected, half-lit. Luminescent lamps are burned down for lighting, and burned packets in the garage. I will appreciate the transformer into three phases.

How to make a benzenerator with your own 220 volts and what is needed for this?

Benefit from your own benzogenerator to seek there is no need, it lies on the surface.

The owners of garages, country sites, private houses (provided that these objects have unreliable energy supply, or not electrified at all) have long appreciated the benefits of backup power supply.

Even if you live in a cottage settlement with a normal supply of electricity, emergency situations are possible. The disappearance of energy for a long time will lead to the spurry of products in the refrigerator in the summer, and violations in the work of the heating boiler in winter.

Therefore, many homeowners acquire industrial generators, the cost of which cannot be called economical.
Another destination for mobile power plants - tourism, expedition and performing work with the help of power tools offline.

This useful device does not apply to too complex devices, so the benzogenerator can be used with their own hands, including 220 V.

Of course, the main reason for this solution is the desire to save. If you acquire components for a mobile power plant in the store - the costs of the details will exceed the savings on the assembly.

Therefore, a profitable home-made benzogenerator will become, only if there are conditionally free components.

The most expensive spare parts are: Drive (gasoline engine) and an electric motor that will perform as a generator. It is them that need to be selected from the existing in the storey "Klama".

What power plant can be chosen for the generator?

First of all - power. The following ratio is used in mobile power systems: for each kilowatt produced electricity (not in peak, and in normal mode) is supplied 2-3 l / from the engine.

Important! This proportion works with competently selected components and minimal losses. It should be remembered that even the most inexpensive generator from "Podnebyny" is designed by engineers.

As a rule, benzogenerators are developed in the complex, that is, a generating element is developed under a certain motor. For homemade installation, choose a coefficient of 2-4 l / s per 1 kilowatt energy. Otherwise, at full load, the engine will quickly fail.

In practice, collecting a power station "From what was", the home masters often set a pair of motor / generator without prior calculation. Sometimes there are options for the "splicing" of a fairly powerful engine, on the occasion of the familiar wrestler bought for a bottle of mogon, with a motorcycle from the sewing machine. And vice versa.
It is recommended to collect the most of the technical information about the components before calculating their compatibility.

Important! When calculating the pair, the generator / engine should consider the final load power (taking into account the electrical body supply and losses on the conversion), and not clean power on the generator winding.

Engine from chainsaws or trimmer

Unpretentious mechanism, very easy to maintain. As a rule, two-stroke.
There are both advantages in such a scheme. On the one hand, you are not bothering the question of which oil to fill in the benzogenerator (it is added to gasoline, as on old mopeds). Maintenance is actually no class.

On the other hand, high fuel consumption and sharp smell from the muffler. The removal of exhaust gases from the benzogenerator is required, especially if it is located near the housing.

Power does not exceed several L / s, respectively, the generator is enough for lighting, maintaining the health of the heating boiler pump and charging for the mobile phone. At low load can work a couple of hours.

Motor from wheeled lawn mower

We are not very common with such aggregates, but you can find a suitable instance of a motor from a broken unit.
Power reaches 3-5 l / s, this is already an application for full nutrition for the country house. You can even turn on a small refrigerator. Four-stroke models come across. This allows you to save fuel, get more eco-friendly exhaust, and noise from such motors less. The maintenance is more complex, however, this fact levels high reliability, and the ability to operate 4-6 hours under load.

Engine from moped (motorcycle)

The moped motor is suitable for medium power generators. Depending on the model, you can remove the power of 2-3 kW.

Engine from a motorcycle (type "Java" or "Izh") is generally a find for the generator.
The power of more than 25 l / s makes it safe to connect the generating installation of 5 kW. This is a full power supply for a private house. If you also use the gearbox, you will receive a relatively economical installation. The routing of the generator will determine exactly at what speed the power is produced with efficient load.

The main advantage of such motors is the simplicity of service and the ability to work for a long time. Perhaps the most accessible (in the search plan) option.

Important! When using such engines it is necessary to provide forced ventilation.

Otherwise you can overlay cylinders. Engines for mopeds and motorcycles are designed for operation in the incoming flow of air.

Let it not seem too ambitious idea. Find in the car market from Moskvich or Zaporozhets will not be difficult. Cost kopeck, you can buy two at once, on parts.

Such aggregates with tape and passage are repaired. If a respected reader of other opinions - for you this material is not a guide to action, but just interesting information.
Alteration of such a motor into the drive for the benzogenerator with their own hands, does not represent complexity. Install on a solid foundation, display the gas pedal and clutch on the manual drive, and even the gearbox can be used.

The main advantage is in fact an unlimited period of work. Cooling the motor from ZAZ air, he blows himself. You do not even have to connect the electric starter for the benzogenerator with your own hands, the motor simply starts the key from the standard startup system.

The capacity of 30-40 l / s allows you to collect a 10 kW generator. True, it will be rather stationary than the mobile version.

How to make a benzogenerator, having a ready-made power plant?

The answer lies on the surface - to connect the generator to the gasoline motor. Where to take it? Any electromotor, with the correct organization of the winding excitation system, becomes the generator.

There are two directions of creating homemade generators:

It receives a torque from the engine of your car, and produces a direct current voltage of 14 volts.
Nothing should be invent. It is enough to watch the power characteristics, and select a small engine from those listed above.

The main condition is a serviceable voltage regulator and preferably "live" windings. However, if you got a burned copy - not trouble. How to remove anchor from the electrical installation of a benzogenerator, any radio amateur knows.

You can rewind the winding in one evening. In principle, if you independently be able to collect a mini power plant, you can sit down to write a book: "Fault of a benzogenerator and ways to eliminate them." This is extremely useful experience.

Cleaning the source of electricity in a clean field is a problem. A familiar with the device "Kulibin" can restore the work without calling the wizard.
The only drawback, however, is essential - voltage of 12-14 volts. Lighting, charging mobile devices, Music and computer connection - no problem. But for the home you need 220 volts. Recall the voltage converter, for example, from the old uninterrupted room.

Here the situation is more difficult (truth and cheaper, there is no need to look for a converter). Any electromotor can be made by the generator by connecting it to the drive.
There are nuances. To excite windings in the generator mode, a capacitor diagram is required (see figure) and accurate selection of revolutions.
If you read up to this place - there is no point in explaining how from the 3-phase source 380V to get one phase 220V. This is the topic of a separate article.

For measuring revolutions, a tachometer will be required. You connect the engine to the network, and measure the speed of rotation. Add 5% -10% to the resulting turnover, and get the optimal rotation speed of the shaft to excite the generator windings.

Benzogenerator with your own hands at home: video and details

Situations with power outages or the absence of a supply network are forced to think about the backup current source. A good solution to the problem is to buy or make a benzogenerator with your own hands.

Among all existing generators, gasoline is in popularity in the first place.

What are they good?

• Easy to operate;
• Compact and mobile;
• Possess high performance;
• Easily repaired;
• At a price cheaper than diesel generators.

Baseline benzogenerators are used in emergency shutdowns as replacement of the current source. The owners of cottages, construction sites, where energy has not yet been completed, provide worthy to life geologists, hunts, reindeer husbandls, drillings - to everyone who is forced to work in hard-to-reach areas. Good assistant to home masters at the cottage or in the garage. It is possible to replace manual work on the mechanized even where the use of electricity is not available. Through the generator plug lights, electrical appliances and tools, household appliances.

When connecting devices, pay attention to the allowable voltage - if the generator is designed for 127 volts, then the devices made under voltage 220 volts will not be able to work with the stated power.

The smooth operation of the benzenerator depends on the power of the device, the volume of the fuel tank, the load value. There are models capable of providing work under load up to one and a half thousand hours.

Device

The principle of operation of the gasoline generator is based on the conversion of the energy obtained during the combustion of gasoline into electrical. Composite parts of the benzenerator:

• Gas engine;
• Electric engine 127, 220 or 380 V;
• Fuel tank;
• Launcher;
• Capacitors;
• Electrical machines and switches;
• Voltmeter;
• Outlets for connecting electrical appliances.

Industrial models are equipped with additional features that allow you to control all work parameters. Especially convenient ABR (automatic input of backup power in emergency situations). All device is mounted on a comfortable rigid frame equipped with wheels and handles for transportation. The factory casing is much more beautiful and stronger homemade. Below is a picture with the indication of all parts of the gasoline generator.

For those who are well versed in electrical engineering and knows how to work with their hands, make the benzogenerator with their own hands.

Where to begin?

Based on the size of the required loads for the simultaneous turning on the instruments, all the main elements are selected.

The optimal performance indicators are achieved by the correct selection of power of gasoline and electric motors.

To obtain a single-phase current of 220V, a two-stroke gasoline engine is suitable, and if higher capacities are obtained, the choice should be stopped on the four-stroke. Fuel consumption will depend on the selected engine. In addition to the main task - energy generation, the system of noise reduction, lubricants, ventilation, installation of the exhaust pipe for gases should be placed. You will have to buy wheels to ensure the mobility of the device. The casing can be made of metal or plywood.

The benzogenerator based on a two-stroke gasoline engine will help the short-term connection if necessary. When working for a long time and with a large load, it is better to make a four-stroke gasoline engine generator.

The control panel must have a voltmeter, the chain interrupt button, terminals for the grounding, sockets for using energy generated.

It makes sense to engage in independent manufacture of a benzogenerator in the case when you have unused engines from old instruments. Of course, it is possible to buy all components specifically for these purposes, but it will not be possible to get a big savings in this case - the cost of components can even exceed the price of the finished factory model.

In practice, motorcycle or car engines often use engines from mowers, chainsaws and other devices.

Generator with engine from a / m Volga 21

The simplest benzogenerator

As an example, we will analyze the simplest homemade design based on chainsaws and an electric motor from the old washing machine:

1. The electric motor from the washing machine is secure to the chainsaw tire using a specially manufactured sustainable bracket.
2. On the drive shafts of both engines we dress the pulleys and connect them with the help of belt transmission.
3. The button for adjusting the engine speed chainsaws located on the handle, we supply an additional device to adjust the pressing force. A simple bolt fixed by the clamp will perfectly cope with it. To increase the revolutions, it will be enough to twist it, and to reduce it - weaken.
4. In parallel, we attach two capacitors calculated at the power of 400-450 volts in parallel.

Video shows a generator with an engine from a washing machine

This simplest installation is capable of issuing a current of 220 V 180 A, which is enough for meals a drill, screwdriver, lighting devices.

Such an elementary device is capable of making almost any master. Of course, with the exception of cases when a person does not see the difference between the engine and the carburetor, or the word bracket and the container for it sound the same. It is completely unacceptable the manufacture of electrical devices for a person who does not know the differences between the concepts of power (Watt), the current (amps) and the voltage of the chain (volt). More complex designs require basic knowledge and skills that will help correctly calculate the power of the engines, ensure the safe use of the finished design, to properly configure all the parameters.

On the Internet on the wizard forums discuss different homemade structures. For those who wish to replenish the ranks of "self-tech", participation in discussions will bring much benefit - you can get a lot of useful tips on the device new or repairing old. Visibility to see the manufacturing process will help special video. What to choose a silencer, electric starter, is it possible to make an autorun function - you can find an answer to all of interest questions. Would you like to go further and put the wind generator on the site to save electricity? What current is needed at the output - 12 or 16 e? Instructions for any topic is enough, study and use the best of them in the case.

Those who decided to make the benzogenerator with their own hands, it is necessary to correctly appreciate their capabilities. Unsuccessful attempts can cause damage to household appliances or even become a threat to life.

The video shows another generator with your own hands, let's see

Working with electrical devices places increased safety requirements and does not forgive carelessness. Be very careful and neat!

Pros and cons of the homemade aggregate

• The ability to "extend the life" of old engines;
• If you need to repair, there will be no difficulties - you know every construct screw;
• Improving self-esteem - successfully manufactured functional apparatus will be the subject of your pride;
• The ability to use as a power when carrying out welding;
• Saving funds, replacement of manual labor at a more progressive.

1. The laboriousness of the process, many operations require special tools and premises.
2. In the manufacture of instruments at home, many functions present in industrial samples are lowered.
3. If there are no old details in the presence, the purchase of new in stores can do too expensive.
4. There is no possibility of connecting ABR (automatic entry of the reserve).

A homemade benzogenerator can be a good alternative to factory models in cases where there is not enough funds for the purchase or need for its use occurs infrequently. For continuous and regular use, it is better to purchase a ready-made benzogenerator for 220 or 380 volts with a factory warranty. If, of course, the alteration of various devices and devices is not your favorite activity. And it is desirable that you have had the skills of different works - you will need a lot of manual operations, welding and installation work.
