Halbach permanent magnet bearing tapered triangular section of the permanent magnet rings

The present invention discloses a permanent magnet bearing triangular tapered cross section Halbach permanent magnet rings of the stator comprises a shaft and a corresponding mount, fixedly mounted on the rotary shaft of the right triangle cross section as the shaft mount, the shaft bevel mount moving the stack ring is assembled, the stator mounting seat toward the inner slope movable ring is assembled in the same stack of a plurality of magnetic force. The present invention also discloses a method for determining the Halbach permanent magnet bearing species tapered triangular section of the permanent magnetic rings. Apparatus and method of the present invention, and having a large axial and radial magnetic bearing capacity; Halbach tapered established analytical model of the permanent magnetic bearing triangular cross section permanent magnet rings such that the amount of calculation decreases the magnetic force, to facilitate the permanent magnet bearing design and optimization.
