Abstract
A magnet bearing arrangement comprising a stator and a rotor disposed within the stator. A first set of adjacent annular permanent magnet members is secured to the surface of the rotor and a second set of adjacent annular permanent magnet members is secured to the inner surface of the stator, the first and second sets of permanent magnet members being arranged in axial juxtaposition so as to generate repelling magnetic forces that stabilize movement of the rotor in the radial direction. A plurality of annular windings are positioned on the stator adjacent the second set of permanent magnet members for generating a magnetic force in response to a sensor for stabilizing axial movement of the rotor.
