Abstract: An electromagnetic machine includes a spherical stator, an armature, a first coil, and a second coil. The spherical stator has an outer surface, and the outer surface has a plurality of spaced-apart protuberances formed thereon. Each protuberance extends radially from, and is disposed normal to, the outer surface. The armature is disposed adjacent to the spherical stator and includes a magnet that emanates a magnetic field. The magnet has at least one of its magnetic poles facing the spherical stator. The first coil is wound around at least a portion of the spherical stator, and is disposed between the plurality of spaced-apart protuberances and along latitudinal lines of the spherical stator. The second coil is wound around at least a portion of the spherical stator, and is disposed between the plurality of spaced-apart protuberances and along longitudinal lines of the spherical stator.

Abstract: An electrohydraulic servo valve (EHSV) includes a housing assembly, a spool valve, an armature, a control mechanism, and a feedback spring. The spool valve is movably disposed within the housing assembly. The armature is rotationally mounted on the housing assembly. The control mechanism is coupled to the armature and is rotatable therewith. The feedback spring is coupled between the control mechanism and the spool valve, and includes a helical coil that is disposed on and engages the control mechanism, and a cantilever portion that extends from the helical portion to a terminus that engages the spool valve.

Abstract: A multi-axis gimbal assembly includes a spherical armature, a first coil, a second coil, a third coil, a bracket, a stator, and a motor. The spherical armature has first, second, and third perpendicularly disposed axes of symmetry. The first coil is wound about the first axis of symmetry, the second coil is wound about the second axis of symmetry, and the third coil is wound about the third axis of symmetry. The bracket is rotationally coupled to the spherical armature to allow relative rotation between the spherical armature and bracket around only the first axis of symmetry. The stator is rotationally coupled to the bracket to allow relative rotation between the stator and bracket around only the second axis of symmetry. The motor is coupled to the stator and is configured to simultaneously rotate the stator, the bracket, and the spherical armature around the third axis of symmetry.
