Abstract: A two degree-of-freedom electromagnetic machine includes an inner stator, a plurality of stator windings, an outer stator, a voice coil winding, a rotor, a plurality of spin magnets, and a plurality of tilt magnets. The plurality of stator windings, when electrically energized, impart a torque on the rotor that causes the rotor to rotate, relative to the inner and outer stators, about a first rotational axis, and the voice coil winding, when electrically energized, imparts a torque on the rotor that causes the rotor to rotate, relative to the inner and outer stators, about a second rotational axis that is perpendicular to the first rotational axis.

Abstract: A multi degree-of-freedom electromagnetic machine includes an outer case, an inner case, a stator, stator windings, a voice coil winding, a tilt magnet, a rotor, and rotor magnets. The inner case is disposed within an inner cavity of the outer case and is mounted to rotate relative to the outer case about one or more rotational axes. The stator is fixedly mounted within the inner case, and the stator windings are wound thereon. The voice coil winding is fixedly coupled to either the inner surface of the outer case or the outer surface of the inner case. The tilt magnet is fixedly coupled to either the outer surface of the inner case or the inner surface of the outer case. The rotor is rotationally mounted within the inner case and is operable to rotate, relative to the stator, about a rotational axis.

Abstract: A two degree-of-freedom motor includes a stator, a plurality of stator windings, a rotor, a shaft, a limited angle torque motor, and a spring. The stator has a main body and a plurality of stator poles. The stator windings are wound around the stator poles. The rotor is spaced apart from the stator and includes a plurality of magnets and is configured to rotate about a first rotational axis. The shaft is coupled to the rotor and is rotatable therewith and and has a shaft first end and a shaft second end. The limited angle torque motor is coupled to the shaft first end, and is operable to supply a torque that causes the shaft, the rotor, and the stator to rotate about a second rotational axis that is perpendicular to the first rotational axis. The spring is fixedly mounted and is coupled to the limited angle torque motor.
