Specific methods and materials: use an electric vehicle rear wheel with 8 wires, 5 fine wires (Hall wires) are not used, the remaining 3 wires output AC power, connect to a three-phase bridge rectifier to obtain a DC output, charge the bottle, then connect a 1000-2000 watt home inverter to complete the circuit. Then add a fan to the wheels and install it on a pole about 6 meters high.
Actually, if you spin the rotor at a certain speed, there will be electricity (induced current).
You can also disassemble the motor of the electric toy car, connect a small bulb to the positive and negative terminals of the motor, then turn the motor rotor hard, you will find that the light turns on.
If you are making a small generator (providing a set of small LED lights), I suggest using a DC motor fan motor, as it issimpler (the direction of the current generated will not change).
But to make a motor, you need power to turn the generator, so you have to find another motor or machine to drive the generator, so it's quite inconvenient. You might as well find a transformer to convert the 220V AC current to the LED's rated voltage.
If you just want to make some small inventions as a personal hobby, just follow what I said above.
Actually, I've done something similar before out of curiosity, but at that time I was using the motor from a four-wheel drive toy. The above is just my personal experience, I hope it is helpful to you!
I wish you success!
