Abstract
Aspects of the subject disclosure relate to an electric motor that includes a rotor with both permanent magnets and operable coils. The coils of the rotor can be operated to generate a temporary magnetic field that supplements the permanent magnetic field of the permanent magnets. Accordingly, the amount of torque output by the rotor can be controlled by operating the coils of the rotor as needed.
