1) It is impossible to spin at more than 50,000 rpm. Theoretically you can rev at 200 rpm per minute, but in reality you won't be able to manage it until you hit 100 rpm, and the throttle you made can do that too.
2) Regarding the question of power, it cannot be higher than the original power of the engine (its structure is limited. Moreover, it depends on how much power you can generate , multiplied by). the efficiency of about 0.7, and then you How long can it be shaken manually?
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 wind. generator. The effect is good,
You need to make the bracket yourself, make it swivel, then make a fin for the navigation, so that everything is together. The lead cable must therefore be longer. that it will not break even if it is wrapped around the bracket more than 10 times, but you need to unwind the twisted wires every day, but you can save the electrical slip ring, the technology is relatively simple
Attach the capacitor at the output end to help create the voltage and install a low power switch or overcurrent fuse to prevent the generator from overloading
Such a generator also has disadvantages , that is, the frequency changes with the output power, the voltage fluctuation is relatively large, and it is easy to burn the bulb. It can be used for rectification and charging, and the light needs to be converted into direct current. Yes, the price will be much more expensive. .
Network-connected operation may resolve such problems, but it will result in equalnew 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 power backflow problem, but the price of the system will increase and the gain will exceed the loss.
Note that the generator made this way does not have overspeed protection and will be more dangerous on windy days.
