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.
