To overcome the defects of the present hybrid-type magnetic bearing, a structure design scheme of a new hybrid-type permanent magnet biased magnetic bearing with rotor magnet is presented. And the flux paths of magnetic bearing are analyzed and calculated by using equivalent magnetic circuit. The calculation of maximum loading force and maximum rising buoyancy are discussed. The design results of prototype bearing are given and prototype experiment is carried out. Theoretical analysis and prototype experiment show that the new magnetic bearing has simple configuration, excellent performance.
