1. An electro-mechanical energy conversion device comprising:

  • a stator comprising a first coil of a first magnetic polarity mounted on a first side of the stator and a second coil of an opposite polarity mounted on an opposite side of the stator;

    a rotor rotationally mounted in the stator, the rotor including at least two permanent magnets mounted circumferentially thereon, a first magnet on a first side of the rotor having a first outward polarity and a second magnet on an opposite side of the rotor having an outward polarity opposite the first polarity;

    a direct current power source connected to the coils, the output of the power source being at least 450 volts in a range of 30 to 40 milliamperes;

    a switching device that reverses the polarity of the first and second coils every 180°

    of rotor rotation; and

    a non-linear, capacitive, voltage-limiting load connected to the coils for rapidly dumping magnetic energy from the coils when the switching device reverses the polarity of the first and second coils.
