Abstract: A multi-degree-of-freedom electromagnetic machine includes a spherical armature, a first coil, a second coil, a third coil, a structure, a stator, and a bracket. The spherical armature has a first axis of symmetry, a second axis of symmetry, a third axis of symmetry, and the first, second, and third axes of symmetry are disposed perpendicular to each other. The spherical armature and structure are rotatable together, relative to the bracket and the stator, about the first axis of symmetry; the spherical armature, structure, and bracket are rotatable together, relative to the stator, about the second axis of symmetry; and the spherical armature, structure, bracket, and stator are rotatable together about the third axis of symmetry.

Abstract: A two degree-of-freedom actuator includes a first linkage, a second linkage, a third linkage, a magnet, a winding panel, and a plurality of windings. The second linkage is rotationally coupled to the first linkage, whereby the first linkage is rotatable, relative to the second linkage, about a first rotational axis. The third linkage is rotationally coupled to the second linkage, whereby the first and second linkages are rotatable, relative to the third linkage, about a second rotational axis that is perpendicular to the first rotational axis. The magnet is fixedly mounted on the first linkage. The winding panel is fixedly mounted to the third linkage and has an inner surface and an opposing outer surface. The inner surface faces the magnet and is spaced apart therefrom. The windings are wound around the winding panel.
