Just use an electric fan to modify it. Use a household electric fan motor with a power of about 50W and match it with an industrial electric fan blade (power of about 2~300W) to create a wind turbine. well.
You need to make the bracket yourself, make it swivel, then make the rear fin for navigation, so that it is all together. The lead cable should be longer, so that it does not break. even if it is wrapped around the support more than 10 times, but this must be done every day. Unwind the twisted wires, but you can omit the electrical slip ring. The technology is relatively simple.
Repair the capacitor. at the output end to help create voltage, and install a low-power switch or overcurrent fuse to prevent the generator from operating in the event of an overload.
This type of generator hasalso disadvantages, that is to say that the frequency changes with it. the output power and voltage fluctuation are relatively large, making it easy to burn out the bulb. It can be used for grinding and charging. The light needs to be converted to direct current, and the price is also high. more expensive.
Grid-connected operation can solve such problems, but it will also lead to new problems. When the wind power is insufficient, the wind turbine turns into an electric fan and it is easy to burn the motor. is better to cut off the start capacitor or It is also possible to change the direction and install the fan blades in another direction, but low winds will still consume some power. Installing a power relay can solve the problem of power backflow, but the system price will increase and the gain exceedsra the loss.
Note that the generator made this way does not have overspeed protection and will be more dangerous on windy days.
