Patent ID: 8131413

Claim:
An electric motor for converting a vehicle with a wheel structure to an electric vehicle comprising: a. a rotor comprising a first plurality of magnets mounted to a first rotor side, a second plurality of magnets mounted to a second rotor side, and a rotor gap; b. a first stator adjacent the first rotor side and comprising a first plurality of winding coils and a first stator gap; c. a second stator adjacent the second rotor side and comprising a second plurality of winding coils and a second stator gap; d. a connector for removably attaching the motor to a wheel structure such that the wheel rotates when the rotor rotates; e. a connector for removably attaching the motor to a frame structure such that the second stator remains substantially stationary when the rotor rotates; and f. a direct current power source electrically connected to the first stator and second stator; and wherein the first plurality of winding coils comprises a different number of winding coils than the first plurality of magnets comprises magnets, and wherein the second plurality of winding coils comprises a different number of winding coils than the second plurality of magnets comprises magnets; and wherein the first plurality of magnets comprises n magnets, wherein the second plurality of magnets comprises n magnets, wherein the first plurality of winding coils comprises n ±1 winding coils, and wherein the second plurality of winding coils comprises n ±1 winding coils.
