A small system which is used in watches has a gearbox which contains four planetary gears, these gears will run by a flat spiral spring. There is a magnet at the end of this system which is surrounded by a coil and will create a weak current during rotation.
I need you design a circuit which can stabilize the speed of rotation so that it won’t be more than the desirable limit.
