Patent attributes
A multi-degree-of-freedom electromagnetic machine includes a stator, an armature, and a control. The stator includes a first, second, and third stator conductors that follow first, second, and third trajectories that are all different, and that together form a general shape of a surface. The armature is disposed adjacent to, and is movable relative to, the stator, and includes a plurality of spaced-apart armature coils. Each armature coil is configured, upon being electrically energized, to generate a magnetic field. The control is coupled to the first, second, and third stator conductors, and to the armature coils and is configured to: (i) supply DC to the stator conductors, and (ii) supply DC to one or more of the armature coils, to thereby generate one or more magnetic fields that interact with the stator conductors and vary an orientation of the one or more magnetic fields relative to the stator conductors.
