An extremely energy efficient, compact, integrated hybrid five axis passive and active magnetic bearing system is developed for suspending a rotor within a non-rotating stator without conventional rolling element or fluid film bearings wherein 1) an axial permanent magnetic set of poles generates a magnetic flux path creating an axial repulsive force which keeps the rotor axially centered in the stator without using a thrust disk or radial thrust faces, 2) two radial electromagnetic bearings generate radial magnetic flux paths which create radial forces which keep the rotor radially centered in the housing, and 3) an integrated axial/radial permanent flux path which provides a bias flux for the radial bearings.
