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 hybrid spherical motor includes a first gear box, a second gear box, a yoke arm, a brushless direct current (BLDC) motor, a spherical stator, and a spherical armature. The split armature, in response to the spherical stator being energized, rotates about a first rotational axis, thereby causing the first gear box input connection and the second gear box input connection to rotate about the first rotational axis, and the yoke arm rotates about the first rotational axis in response to the first gear box input connection and the second gear box input connection being rotated about the first rotational axis, whereby the BLDC motor rotates about the first 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.

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.
