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 brushless DC motor includes a stator, a rotor, a plurality of distributed stator windings, and a stator voice coil winding. The stator includes an inner stator structure and a plurality of arc-shaped stator poles. The inner stator structure includes a main body and a plurality of spokes that are spaced apart from each other to define a plurality of stator slots. Each arc-shaped stator pole is connected to a different one of the spokes. The rotor is spaced apart from the stator, includes a plurality of magnets, and is configured to rotate about a plurality of perpendicular axes. The distributed stator windings are wound around the plurality of spokes and extend through the stator slots. The stator voice coil winding is wound around the outer surfaces of the arc-shaped stator poles. The arc-shape and spacing of the stator poles define the stator as being spherically shaped.

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.

Abstract: A multi-degree-of-freedom electromagnetic machine includes a spherical structure, a first coil, a second coil, a non-magnetic structure, and a Halbach array. The spherical structure has a first axis of symmetry, a second axis of symmetry, and a third axis of symmetry, and the first, second, and third axes of symmetry are disposed perpendicular to each other. The first coil is wound on the spherical structure about the first axis of symmetry, and the second coil is wound on the spherical structure about the second axis of symmetry. The non-magnetic structure is spaced apart from, and at least partially surrounds, the spherical structure. The Halbach array is mounted on the non-magnetic structure and includes N-magnets, where N is a multiple of 4. The spherical structure and non-magnetic structure are mounted to allow relative rotation between the non-magnetic structure and the spherical structure.

Abstract: A system including a magnet configured to move in response to a movement of a wear pin indicator of a brake assembly of a vehicle. A sensor is configured to generate position data corresponding to the magnet. The position data is indicative of a position and/or movement of the wear pin indicator. The system includes a thermoelectric generator configured to generate an electrical signal based on an operation of the brake assembly. The thermoelectric generator is configured to deliver at least a portion of the electrical signal to the sensor. The system includes a mounting bracket configured to mechanically couple a sensor housing to an actuator housing of the brake assembly. The mounting bracket is configured to provide heat to the thermoelectric generator when the mounting bracket mechanically couples the sensor housing and the actuator housing.

Abstract: A stepper motor includes a rotor, a stator, a plurality of stator windings, and a plurality of permanent magnets. The permanent magnets are coupled to the outer surface of the rotor and are spaced apart from the plurality of stator poles, and each permanent magnet is shaped like an arc having an arc length and is circumferentially spaced apart from two adjacent permanent magnets by a spacing angle. In some instance, the arc length of each permanent magnet is equal, and the spacing angles are not all equal. In other instances, the arc length of two or more of the permanent magnets is unequal to the arc lengths of the other permanent magnets, and the spacing angles are not all equal.
