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.

Abstract
An electromagnetic motor with increased torque. The motor has a rotor coil configured to generate a magnetic field. At least two stator coils are connected in series with the rotor coil. Each of the stator coils is configured to generate a respective magnetic field. The motor further includes a plurality of switches configured to generate the magnetic field in each of the respective rotor and stator coils. The switches are configured to generate the magnetic field in the stator coils such that the rotor coil rotates in response thereto. By having the rotor and stator coils connected in series, the torque of the motor is increased.
