Triangular cross section permanent magnet ring stack Halbach permanent magnet bearing

The present invention discloses a triangular cross section permanent magnet ring stack Halbach permanent magnet bearing comprising a rotor and a stator provided corresponding circumference of the rotor shaft of the movable magnetic ring stack of a plurality of sets, the inner peripheral surface of the stator stack a plurality of sets of static ring, and a plurality of sets of the movable ring are a plurality of sets of static magnetic stack constituting a cylindrical shape; static and dynamic magnetic ring are used in accordance with a triangular cross section permanent magnet ring stack Halbach array configuration, static and dynamic magnetic ring and the magnetic ring by a radius different from a triangular cross section permanent magnet rings. The present invention also discloses a method for determining the kind of triangular cross section permanent magnet ring stack Halbach permanent magnetic bearing. Apparatus and method of the present invention to achieve a significant increase in radial or axial forces, the permanent magnet material saving; simple operation process, high accuracy.
