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.

hi, from the current we can generate voltage ( assuming that coil and magenta arrangement has give sine wave) and can measure frequency or rotation.
