  • Mechanical-electric energy converter and watch part comprising this energy converter
    Patent number: 6041022
    Abstract: A mechanical-electric energy converter comprising a wheel for transmitting energy which rotates at a low speed. The teeth of the driving wheel shift the rotor of the generator from its position of equilibrium, causing it to oscillate around the wheel. This converter can produce high angular velocities without a speed-increasing gear train.
