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 multi-degree-of-freedom electromagnetic machine includes a spherical stator, an armature, a payload mount assembly, and a payload. The spherical stator has a first axis of symmetry, a second axis of symmetry, and a third axis of symmetry that are disposed perpendicular to each other. The armature is spaced apart from, and surrounds at least a portion of, the spherical stator, and is mounted for rotation about the first and second axes of symmetry. The payload is spaced apart from the spherical stator and the armature and is coupled to the payload mount assembly and is mounted to rotate about a payload rotational axis that is parallel to the first axis of symmetry and perpendicular to the second axis of symmetry. The payload is disposed such that its center of gravity is at a position where the second axis of symmetry and the payload rotational axis intersect.
