Small gasoline and diesel generator: The combustion of gasoline and diesel drives the engine, and the engine drives the generator to generate electricity.
Small wind turbine: The wind drives the blades and transmission parts to drive the generator to generate electricity.
Solar power generation: Utilizes the photovoltaic principle to generate direct current, which is converted into alternating current through an inverter.
Small hydraulic generator: Water power drives the turbine to drive the generator to generate electricity.
Small thermal power generator: The combustion of biogas turns water into steam, which drives the steam turbine to drive the generator to generate electricity.
A homemade 220v generator requires the following:
220v generator (casing, stator core, stator coil, rotor, permanent magnet, bearings, cooling blades, etc.) .
With a generator, you also need equipment to drive the generator: gasoline engine, diesel engine, fan blades, hydraulic turbine, etc.
It is impossible to make your own generator, so it is better to buy a ready-made one.
Tear apart a small DC motor from an old tape recorder or a used DVD player, and install a small fan blade on the motor shaft, or buy it directly and make sure it comes with a sun hat with a small fan, no batteries. Weld a light-emitting diode on the terminal of the motor, preferably red (eye-catching and low starting voltage). Use the wind to blow the fan blades to drive the motor to rotate.
