ABSTRACT:
A magnetic suspension system for efficiently supporting a rotor of relatively large radius and high available moment of inertia includes concentric stator and rotor elements spaced apart by narrow gaps of relatively large diameter and very small axial extent. A pair of spaced discs in the stator are oppositely polarized by a permanent magnet, their peripheral magnetic field strength being selectively augmented or diminished in predetermined sectors by electromagnet windings thereon. The rotor includes narrow ring faces juxtaposed to said discs, a permanent magnetic polarization being provided between the narrow ring faces. Means are provided for varying the relative electromagnetic contributions in the different sectors to maintain stability of rotor positioning with minimized electric power. SU
