I would like to know on which vehicle you are installing it, is it a car or a moped? What do you want to use the electricity for? I also understand your thinking, but I don't know what you use wind-generated electricity for? Is it to power the lights? Is it for the battery? Or for the engine? If you want to power small things, like LEDs, you can just install a generator on a fan blade, but if you want to power other things, that won't work.
I want to make a small domestic wind turbine (direct current motor to produce electricity). Who can explain the process, the principle (and the gear pairing)? >
Not allowed:
1. There are no permanent magnets in the electric fan motor
2 The Coke can blades are not strong enough to support the rotation of the Coke can. such a big engine.
3. Do existing water pumps use mains power? In this case, your generator must have a sinusoidal AC output. Since the wind is unstable, it must also have a battery to store electrical energy and have a voltage stabilization function. The output power should be greater than the water pump power.
Because it does not conform to the law of conservation of energy, I think your conditional method is impossible to succeed.
Power generation process:
Fan blade --- gearbox --- DC motor --- rectifier bridge (polarity protection) --- - battery
Principle:
The wind rotates the blades (similar to the blades of an electric fan) to drive the gearbox so that the speed of the DC motor exceeds the nominal speed. At this time, the voltage generated on the motor will be equal to. the operating voltageent of the motor, usually 12V or 24V, because the batteries are generally at these voltages.
Difficulty:
To make a gearbox, you must calculate the transmission ratio. For example: the rated speed of the motor is 3000, the fan blade rotates 10 times per minute, and the motor end reaches 3000 rpm. At present, the gear ratio is 1:300.
The above data is obtained from the small power manual generator model I made and is for reference only. reference only.
