1. An electromagnetic motor, comprising:

  • a rotor;

    a stator;

    a rotor coil configured to generate a single-phase magnetic field, the single-phase magnetic field being rotationally fixed with respect to the rotor when excited from a direct current electrical energy source;

    at least two stator coils configured to generate a poly-phase magnetic field that rotates with respect to the stator; and

    a plurality of switches configured to generate the poly-phase magnetic field from the direct current electrical energy source such that the rotor rotates in response thereto;

    the rotor coil being coupled in series with the direct energy source and the plurality of switches.
