What do you need

Our society is accustomed to using equipment and appliances powered by electricity provided to us by local energy companies. In most cases this is the case, however, sometimes we do not have electricity available.The electricity may be cut off during repair work at the station, or there is simply no available electrical network around you, for example, during a hike, or living far from the city. Electricity can be available even where there are no power plants - you just need a gasoline generator to generate power. Gasoline generators can be used to recharge 12-volt batteries in portable equipment. Thanks to the 12 volt batteries, we can use portable equipment away from AC power, however, they have a limited time of use. Use these tips to build your own generator.

Steps

Method 1 of 2: Take Basic Parts for Power

1 Take the engine. The proper size of the motor will depend on the power you need to generate. An engine with a capacity of 5 to 10 horsepower may be best suited for creating a generator. Keep in mind that most engines are rated at 3600 rpm. Such an engine is most often found in lawn mowers; you can find it at a lawn mower store, hardware store, or electrical store.
2 Select a head for an alternator. This head will use an internal magnet to generate electricity when the magnet on the axis is rotated by an external motor. In most cases, an output of 2.5 to 5 thousand watts should be sufficient. When choosing a head, check the motor specifications to see if it can rotate it. Roughly speaking, the generator will be able to produce about 900 watts per horsepower. These heads are available at electrical supply stores.
3 Choose a 12 volt DC generator. Such a generator will generate 12 volts DC current when its axis is rotated by an external motor. The selected generator must have a built-in voltage regulator. A generator with a capacity of about 500 watts should suffice, it will use one more horsepower from the engine. These generators are most commonly found at auto parts stores.

Method 2 of 2: Connect the main parts of the generator

1 Make a mounting plate. The plate can be made of any durable material that can withstand vibration from a gasoline engine. The 3 main parts of our generator (motor, magnetic head and the generator itself) need to be assembled in such a way that their axes are parallel, and the parts of the axles that will need to be connected using rollers are in the same plane. Holes and bolts for installing parts must be in all parts provided by the manufacturer.
2 Install the casters. The rollers must be installed on the axis of the engine, generator and magnetic head. The size of the rollers must be such that the transfer belts are properly tensioned during the rotation of the axles. Select rollers so that they rotate at the speed specified by the manufacturer. In most modern generators, the size of the rollers is 125 to 250 mm. These clips can be purchased at specialized electrical stores.
3 Install the transfer belts. The design of the generator has different wheel sizes so that the axles can rotate at different speeds. Place the transfer belts on the rollers and make sure they sit firmly on them. Correct positioning of the motor will help to achieve the correct belt tension. A curved belt is less likely to slip off the rollers than a conventional belt. These belts can be purchased at electrical supply stores or automobile stores.
4 Place the fuel tank on the plate.
5 Connect the fuel tank. Fill the fuel tank and run a hose from it to the engine.
