Electricity is getting more expensive every day. And many owners sooner or later begin to think about alternative sources energy. We offer as samples fuel-free generators of Tesla, Hendershot, Romanov, Tariel Kanapadze, Smith, Bedini, the principle of operation of the units, their scheme and how to make a device with your own hands.

How to make a fuel-free generator with your own hands

Many owners sooner or later begin to think about alternative energy sources. We propose to consider what an autonomous fuel-free generator of Tesla, Hendershot, Romanov, Tariel Kanapadze, Smith, Bedini is, the principle of operation of the unit, its scheme and how to make a device with your own hands.

Overview of generators

When using a fuelless generator, an internal combustion engine is not required, since the device does not have to convert the chemical energy of the fuel into mechanical energy to generate electricity. This electromagnetic device works in such a way that the electricity generated by the generator is recirculated back to the system through the coil.

Conventional electric generators work on the basis of:
1. Internal combustion engine, with piston and rings, connecting rod, spark plugs, fuel tank, carburetor, ... and
2. Using amateur motors, coils, diodes, AVRs, capacitors, etc.

The internal combustion engine in fuel-free generators has been replaced by an electromechanical device that receives power from the generator and, using the same, converts it into mechanical energy with an efficiency of more than 98%. The cycle repeats over and over. So the concept here is to replace an internal combustion engine that depends on fuel with an electromechanical device.

The mechanical energy will be used to drive the generator and receive the current generated by the generator to power the electromechanical instrument. A fuelless generator that is used to replace an internal combustion engine is designed to use less energy in the generator output.

Tesla generator

The Tesla linear electric generator is the main prototype of the working device. A patent for it was registered in the 19th century. The main advantage of the device is that it can be built even at home using solar energy. An iron or steel plate is insulated with external conductors, after which it is placed as high in the air as possible. We place the second plate in sand, earth or other grounded surface. The wire starts from a metal plate, the connection is made with the capacitor on one side of the plate and the second cable goes from the base of the plate to the other side of the capacitor.

Such a self-made fuel-free mechanical generator of free energy of electricity is fully functional in theory, but for the actual implementation of the plan it is better to use more common models, for example, inventors Adams, Sobolev, Alekseenko, Gromov, Donald, Kondrashov, Motovilov, Melnichenko and others. It is possible to assemble a working device even when redevelopment of any of the listed devices, it will come out cheaper than connecting everything yourself.

In addition to solar energy, you can use turbine generators that operate without fuel on water energy. The magnets completely cover the rotating metal discs, and a flange and a self-powered wire are added to the device, which greatly reduces losses, thanks to this this heat generator works more efficiently than solar. Due to the high asynchronous oscillations, this wadded fuelless generator suffers from eddy electricity, so it cannot be used in a car or to power a house, because. motors can burn out on impulse.

But Faraday's hydrodynamic law also suggests using a simple perpetual generator. Its magnetic disk is divided into spiral curves that radiate energy from the center to the outer edge, reducing resonance.

In this high voltage electrical system, if there are two turns side by side, electric current moves through the wire, the current passing through the loop will create a magnetic field that will radiate against the current passing through the second loop, creating resistance.

How to make a generator

Exist two options work execution:


  1. dry way;

  2. Wet or oily;

wet method uses a battery, while the dry method does without a battery.

Step-by-step instruction how to assemble an electric fuelless generator. To make a fuel-free type wet generator, you will need several components:


  • battery,

  • Charger suitable caliber,

  • AC transformer

  • Amplifier.

Connect the ac to dc transformer to your battery and power amp, and then connect the charger and expansion sensor to the circuit, then connect it back to the battery. Why are these components needed:


  1. The battery is used to store and store energy;

  2. A transformer is used to create constant current signals;

  3. The amplifier will help increase the current supply because the power from the battery is only 12V or 24V, depending on the battery.

  4. The charger is necessary for the smooth operation of the generator.

dry generator works on capacitors. To assemble such a device you need to prepare:


  • generator prototype

  • Transformer.

This production is the most perfect way to make a generator, because it can last for years, at least 3 years without recharging. These two components must be combined using undamped special conductors. We recommend using welding to create the strongest connection. To control the work, a dynatron is used, watch the video on how to connect the conductors correctly.

Transformer-based devices are more expensive, but are much more efficient than battery-powered ones. As a prototype, you can take the model free energy, kapanadze, torrent, brand Khmilnik. Such devices can be used as a motor for an electric vehicle.

Price overview

On the domestic market, generators manufactured by Odessa inventors, BTGi BTGR, are considered the most affordable. You can buy such fuel-free generators in a specialized electrical engineering store, online stores, from the manufacturer (the price depends on the brand of the device and the point where the sale is made).

Fuel-free new generators on the Vega magnet for 10 kW will cost an average of 30,000 rubles.

Odessa plant - 20,000 rubles.

Very popular Andrus will cost the owners at least 25,000 rubles.

Imported devices of the Ferrite brand (an analogue of the Stephen Mark device) are the most expensive in the domestic market and cost from 35,000 rubles, depending on the power.

Unfortunately, domestic power supply organizations do not keep their word. Their contracts signed with consumers are worth nothing. The supply of electricity outside of large cities is unstable, the quality of the supplied current is low (meaning voltage), so residents of small cities and towns always have candles, kerosene lamps in stock, and the most advanced install gasoline current generators. This article will offer another option, which will be indicated by the question, how to make an electric generator with your own hands? Let's look at one version of this device.

Electric generator from walk-behind tractor

Residents of suburban villages have long used walk-behind tractors. After all, today it is, so to speak, the most reliable assistant, without which work in the garden or garden is not carried out. True, like all this type of tools, the walk-behind tractor fails. You can restore it, but as practice shows, it is better to buy a new one.

The owners of the instrument are in no hurry to say goodbye to it, so each owner country house there is one old copy in the pantry. It will be possible to use it in the design of an electric generator with a voltage of 220/380 volts. It will create torque for the current generator, which can be adapted as a conventional induction motor. In this case, a powerful electric motor will be required (at least 15 kW, with a shaft speed of 800-1600 rpm). Why such a large motor power?


It makes no sense to make a home-made generator for a couple of light bulbs, because the issue of fully providing a country house with electricity is being solved. And with an electric motor of small power, it will not work to get enough electricity. Although it all depends on the total power of household appliances and lighting at home. After all, in small dachas except for a refrigerator with a TV, there is nothing. Therefore, advice - first calculate the power of the house, then choose an electric motor-generator.

Assembly of the generator

So, in order to assemble a gasoline generator with your own hands with a voltage of 220 volts, you need to install a walk-behind tractor and an electric motor on one frame so that their shafts are parallel. The thing is that the rotation from the walk-behind tractor to the electric motor will be transmitted using two pulleys. One will be mounted on the shaft of a gasoline engine, the second on the shaft of an electric one. In this case, it is necessary to correctly select the diameters of the pulleys. It is these dimensions that select the frequency of rotation of the electric motor. This indicator must be equal to the nominal, which is indicated on the equipment tag. A slight upward deviation of 10-15% is welcome.

When the mechanical part of the assembly is completed, the pulleys connected by the belt will be installed, you can proceed to the electrical part.


  • First, the windings of the electric motor are connected in a star pattern.
  • Secondly, the capacitors connected to each winding must form a triangle.
  • Thirdly, the voltage in such a circuit is removed between the end of the winding and the midpoint. It is here that a current of 220 volts is obtained, and between the windings of 380 volts.

Attention! Installed in wiring diagram capacitors must have the same capacitance. In this case, the capacitance value is selected depending on the power of the electric motor. It is this ratio that will support the correct operation of the current generator itself, but especially its start-up.

For information, we give the ratio of motor power to the capacitance of capacitors:

  • 2 kW - 60 uF.
  • 5 kW - 140 uF.
  • 10 kW - 250 uF.
  • 15 kW - 350 uF.

Pay attention to some helpful tips given by experts.

  • If the electric motor gets warm, then it is necessary to change the capacitors to elements with a reduced capacity.
  • Typically, for homemade power generators, capacitors with a voltage of at least 400 volts are used.
  • Usually one capacitor is enough for a resistive load.
  • If there is a need to use all three phases of the electric motor to power the house, then a three-phase transformer must be installed in the network.

And one moment. If you are faced with the problem of how to organize heating using a home-made electric generator, then the engine from the walk-behind tractor will be small here (meaning the power of the device). The best option- this is an engine from a car, for example, from an Oka or a Zhiguli. Many may say that such equipment will cost a pretty penny. Nothing like this. You can buy a used car today for a penny, so the costs will be miserable.

Advantages and disadvantages

So, what are the advantages of this device:

  • You console yourself with the thought that you made it yourself. That is, you are proud of yourself.
  • Financial costs are reduced to a minimum. A homemade unit will cost much less than its factory counterpart.
  • If all the assembly steps are carried out correctly, then assembled by your hands electrical equipment can be considered reliable and quite productive.

A few negative points of this kind of devices.

  • If you are new to electrics or are trying, without delving into all the subtleties and nuances of assembly, to make a current generator, then you will fail. The time and money spent by you will be considered thrown to the wind.

In principle, this is the only drawback, which inspires optimism.

Other generator designs

The petrol option is not the only one. You can make the motor shaft rotate different ways. For example, using a windmill or a water pump. Not the most simple designs, but it is they that allow moving away from the consumption of energy in the form of gasoline.

For example, it is also easy to assemble a hydrogenerator with your own hands. If a river flows near the house, its water can be used as a force to rotate the shaft. To do this, a wheel with many containers is installed in its channel. With this design, it is possible to create a flow of water that will rotate a turbine attached to an electric motor shaft. And the larger the volume of each tank, the more often they are installed (the number increases), the greater the power of the water flow. In fact, this is a kind of generator voltage regulator.


With wind generators, things are a little different, because wind loads are not constant values. The rotation of the windmill, which is transmitted to the shaft of the electric motor, must be regulated, adjusting to the required value of the frequency of rotation of the electric motor shaft. Therefore, in this design, the voltage regulator is a conventional mechanical gearbox. But here, as they say, a double-edged sword. If the wind reduces gusts, a step-up gearbox is needed, if, on the contrary, it increases, a reduction gearbox is needed. This is the complexity of the construction of a wind power generator.

Conclusion on the topic

Summing up, you need to understand that homemade power generators are not a panacea. It is better to ensure that the village is constantly fed electricity. It is difficult to achieve this, but you can get compensation for the inconvenience through the courts. And the money already received will be used to purchase a factory gasoline generator. True, you will have to take into account the consumption of expensive fuel (gasoline). But if there is a desire to assemble an electric generator with your own hands, then delve into the topic and try.

A generator is a device that produces products that generate electrical energy or convert it into another. What is a device, how to make a generator, what is the principle of its operation, what is the difference from a synchronous generator? We will talk about this further.

A generator is an electrical machine that converts mechanical energy into electrical current. In most cases, a rotary type is used for this. magnetic field. The apparatus consists of a relay, a rotating inductor, slip rings, a terminal, a sliding brush, a diode bridge, diodes, a slip ring, a stator, a rotor, bearings, a rotor shaft, a pulley, an impeller and a front cover. Often, the design includes a coil with an electromagnet, which generates energy.

DIY generator

It is important to note that the generator is variable and direct current. In the first case, eddy currents are not generated, the device can operate under extreme conditions and has a reduced weight. In the second case, the generator does not need increased attention and has more resources.

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

Note! The result is a permanent electric magnet. Of the advantages, the high stability of the generated voltage is noted, of the disadvantages is the current overload, since with an excessive load, the regulator increases the current in the rotor winding.

Synchronous apparatus device

The asynchronous apparatus consists of a squirrel-cage rotor and exactly the same stator as the previous model. At the moment of rotation of the rotor, the asynchronous generator induces an electric current and the magnetic field creates a sinusoidal voltage. Since it has no connection with the rotor, there is no possibility to artificially regulate the voltage and current. These parameters change under electrical load on the starter winding.

Asynchronous apparatus device

Operating principle

Any generator operates according to the electromagnetic inductive law, due to the induction of electric current in a closed loop by crossing a rotating magnetic field created using permanent magnets or windings. The electromotive force enters a closed circuit from the collector and the brush assembly along with the magnetic flux, the rotor rotates and generates voltage. Thanks to spring-loaded brushes, which are pressed against the plate collectors, an electric current is transmitted to the output terminals. Then it goes to the user's network and spreads through the electrical equipment.

Principle of operation

Difference from synchronous generator

A synchronous gasoline generator is not overloaded due to transient conditions that are associated with starting under load from consumers of similar power. He is the source reactive power, while async consumes it. The first one is not afraid of overloads in the set mode thanks to the auto-regulation system through a connection that is inverse to the current with the voltage in the wire. The second has an artificially unregulated cohesion force of the electromagnetic rotor field.

Note! It is important to understand that the asynchronous variety is more popular due to its simple design, unpretentiousness, lack of need for qualified technical maintenance and comparative cheapness. It is set when: there are no high requirements for frequency with voltage; it is supposed to work the unit in a dusty place; there is no way to overpay for another variety.

Application area

An alternator is a multifunctional device, thanks to which energy can be transmitted over long distances and at the same time quickly redistributed. In addition, it turns into light, thermal, mechanical and other energy according to the instructions. Easy to manufacture. Therefore, their scope is wide. Today, such devices are used everywhere: both in industry and in everyday life. They are equipped with a powerful motor.

For example, an electric and wind generator will be useful at a time when the volt network is turned off, an accident occurs at a power plant, additional energy will be needed in the engine.

Gasoline and magnetic generator, due to its light weight and compactness, can be transported and used in agriculture, in the country, in the forest. It will serve as quick response equipment and help create emergency lighting.

Application area

Device classification

The classification of the device is extensive. Today it is asynchronous and synchronous, with a fixed rotor or stator, single-phase, two-phase and three-phase, with independent or self-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 due to the rotating circular magnetic field, system balance, multi-mode operation and high levels of efficiency.

Equipment classification

Device assembly diagram

You can assemble electric generators for 220 with your own hands by analogy with the production model. This may require video tutorials or study guides. Then you need to correctly connect all the devices of one system. This can be done according to the 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 serial type of winding generator connections is provided. It is important to note that these schemes can only be used if the load of the phases is uniform. Then the topic of how to make a generator at home will be relevant.

Connection diagram star

In general, a generator is a device that converts mechanical energy into electrical energy using a wire version of a magnetic field coil. According to the number of phases, units come with one, two and three phases.

Triangle wiring diagram

You can make it yourself today using the special scheme indicated above.

Very often, lovers of outdoor recreation do not want to give up the conveniences of everyday life. Since most of these amenities are connected to electricity, there is a need for an energy source that you can take with you. Someone buys an electric generator, and someone decides to make a generator with their own hands. The task is not easy, but it is quite feasible at home for anyone who has the technical skills and the right equipment.

Generator type selection

Before deciding to make a homemade 220 V generator, you should think about the feasibility of such a solution. You need to weigh the pros and cons and determine what suits you best - a factory sample or a homemade one. Here The main advantages of industrial devices:

  • Reliability.
  • High performance.
  • Quality assurance and availability of technical service.
  • Security.

However, industrial designs have one significant drawback - a very high price. Not everyone can afford such units, so It is worth thinking about the advantages of homemade devices:

  • Low price. Five times, and sometimes more, lower price compared to factory power generators.
  • The simplicity of the device and a good knowledge of all the nodes of the apparatus, since everything was assembled by hand.
  • The ability to upgrade and improve the technical data of the generator to suit your needs.

A do-it-yourself electric generator at home is unlikely to be of high performance, but it is quite capable of providing the minimum requirements. Another disadvantage of homemade products is electrical safety.

It is not always highly reliable, unlike industrial designs. Therefore, you should be very serious about choosing the type of generator. Not only saving money, but also the life, health of loved ones and oneself will depend on this decision.

Design and principle of operation

Electromagnetic induction underlies the operation of any generator that produces current. Anyone who remembers Faraday's law from the ninth grade physics course understands the principle of converting electromagnetic oscillations into a direct electric current. It is also obvious that creating favorable conditions for supplying sufficient voltage is not so simple.

Any electric generator consists of two main parts. They can have different modifications, but are present in any design:

There are two main types of generators, depending on the type of rotation of the rotor: asynchronous and synchronous. Choosing one of them, take into account the advantages and disadvantages of each. Most often, the choice of craftsmen falls on the first option. There are good reasons for this:

In connection with the above arguments, the most likely choice for self-manufacturing is an asynchronous generator. It remains only to find a suitable sample and a scheme for its manufacture.

Assembly order of the unit

First you need to equip the workplace with the necessary materials and tools. Workplace must comply with the safety regulations for working with electrical appliances. From the tools you will need everything related to electrical equipment and car maintenance. In fact, a well-equipped garage is quite suitable for creating your own generator. Here is what you need from the main details:

Having collected necessary materials, proceed to the calculation of the future power of the device. To do this, you need to perform three operations:

When the capacitors are soldered in place, and the desired voltage is obtained at the output, the structure is assembled.

In this case, the increased electrical hazard of such objects should be taken into account. It is important to consider proper grounding of the generator and carefully insulate all connections. Not only the service life of the device depends on the fulfillment of these requirements, but also the health of those who will use it.

car engine device

Using the scheme for assembling a device for generating current, many come up with their own incredible designs. For example, a bicycle or water-powered generator, a windmill. However, there is an option that does not require special design skills.

In any car engine there is an electric generator, which is most often quite serviceable, even if the engine itself has long been sent to the scrap. Therefore, having disassembled the engine, you can use finished product for your purposes.

Solving the problem with the rotation of the rotor is much easier than thinking about how to make it again. You can simply restore a broken engine and use it as a generator. To do this, all unnecessary components and devices are removed from the engine.

wind dynamo

In places where the winds blow without stopping, restless inventors are haunted by the waste of nature's energy. Many of them decide to create a small wind farm. To do this, you need to take the electric motor and convert it into a generator. The sequence of actions will be as follows:

Having made his own windmill with a small electric generator or a generator from a car engine with his own hands, the owner can be calm during unforeseen disasters: there will always be electric light. Even after going out into nature, he will be able to continue to enjoy the convenience provided by electrical equipment.

Constant and uninterrupted supply of electricity in the house is the key to a pleasant and comfortable pastime at any time of the year. To organize an autonomous power supply for a suburban area, we will have to resort to mobile installations - electric generators, which, in last years especially popular due to the large range of different capacities.

Scope of application

Many are interested in how to make an electric generator for suburban area? We will talk about this below. In most cases, an asynchronous alternator is applicable, which will produce energy for the operation of electrical appliances. In an asynchronous generator, the speed of rotation of the rotors than in a synchronous one and the efficiency will be higher.

However, power plants have found their application in a wider range, as an excellent means for extracting energy, namely:

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

The unit is switched on using the input voltage. Often, the device is connected to power to start, but this is not a very logical and rational solution for a mini-station, which itself must generate electricity, and not consume it to start. Therefore, in recent years, generators with self-excitation or series switching of capacitors have been actively produced.

How an electric generator works

An asynchronous power generator produces a resource if the speed of rotation of the motor is faster than synchronous. The most common generator operates on parameters from 1500 rpm.

It produces power if the rotor at start is running faster than the synchronous speed. The difference between these figures is called slip and is calculated as a percentage of the synchronous speed. However, the stator speed is even higher than the rotor speed. Due to this, a stream of charged particles is formed that changes polarity.

Watch the video, how it works:

When energized, the connected power generator device takes control of the synchronous speed by independently controlling the slip. The energy leaving the stator passes through the rotor, however, the active power has already moved to the stator coils.

The basic principle of operation of an electric generator is to convert mechanical energy into electrical energy. To start the rotor to generate power, a strong torque is needed. The most adequate option, according to electricians, is "perpetual idling", which maintains one speed of rotation during the operation of the generator.

Why use an asynchronous generator

Unlike a synchronous generator, an asynchronous one has a huge number of advantages and benefits. The main factor in choosing the asynchronous option was the low clear factor. A high clear factor 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 clear factor value of 5-15%, in asynchronous generators it does not exceed 2%. It follows from this that an asynchronous power generator produces only useful energy.

A little about the asynchronous generator and its connection:

An equally significant advantage of this type of power generator is the complete absence of rotating windings and electronic parts that are sensitive to damage and external factors. Therefore, this type of apparatus is not subject to active wear and tear and will last longer.

How to make a generator with your own hands

Device asynchronous alternator

The purchase of an asynchronous electric generator is a rather expensive pleasure for the average resident of our country. Therefore, many craftsmen resort to solving the issue of self assembly device. The principle of operation, as well as the design, is quite simple. With all the tools, assembly will not take more than 1-2 hours.

According to the above-described principle of operation of the electric generator, all equipment should be adjusted so that the rotations are faster than the engine revolutions. To do this, you must connect the engine to the network and start it. Use a tachometer or tachogenerator to calculate RPM.

After determining the value of the engine speed, add 10% to it. If the rotation speed is 1500 rpm, then the generator should be running at 1650 rpm.

Now you need to remake the asynchronous generator "for yourself", using capacitors of the required capacities. Use the following plate to determine the type and capacity:

We hope that it is already clear how to assemble an electric generator with your own hands, but please note: the capacitance of the capacitors should not be very high, otherwise the generator running on diesel fuel will get very hot.

Install the capacitors according to the calculation. Installation requires a fair amount of attention. Ensure good insulation, if necessary, use special coatings.

Based on the engine, the generator assembly process is completed. Now it can already be used as a necessary source of energy. Remember that in the case when the device has a squirrel-cage rotor and produces a rather serious voltage that exceeds 220 volts, it is necessary to install a step-down transformer that stabilizes the voltage at the required level. Remember that in order for all appliances in the house to work, there must be strict control of a home-made 220-volt electric generator in terms of voltage.

Watch the video, the stages of work:

For a generator that will run at low power, one-phase induction motors from old or unwanted household appliances can be used to save money, for example, washing machines, drainage pumps, lawn mowers, chainsaws, etc. Motors from such household appliances should be connected in parallel with the winding. Alternatively, phase-shifting capacitors can be used. They rarely differ in the required power, so it will need to be increased to the required performance.

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

The ready-to-operate generator should be installed so that it is not affected by precipitation and Environment. Take care of an additional casing that will protect the installation from adverse conditions.

Almost every asynchronous generator, whether it is a brushless, electric, gasoline or diesel generator, is considered a device with enough high level danger. Handle such equipment very carefully and always keep it protected from external weather and mechanical influences or make a casing for it.

We watch video good advice specialist:

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

  • Equip the generator with an on/off button if possible. You can use manual start to start.
  • Some power generators need to be grounded before use, carefully assess the area and select a site for installation.
  • When converting mechanical energy into electrical energy, sometimes the efficiency can drop to 30%.
  • If you are not confident in your abilities or are afraid to do something wrong, we advise you to purchase a generator in the appropriate store. Sometimes the risks can turn out to be extremely deplorable ...
  • Watch the temperature asynchronous generator and its thermal regime.

Results

Despite their ease of implementation, homemade power generators are very painstaking work that requires complete focus on design and correct connection. The assembly is financially feasible only if you already have a workable and unnecessary engine. Otherwise, you will pay more than half of its cost for the main element of the installation, and the total costs may significantly exceed the market value of the generator.
