ABSTRACT:
A fault tolerant active magnetic bearing system comprises a magnetic bearing having a rotor mounted for rotation within a stator and for coupling to a shaft. An electric power distribution system is energized from a multi-phase switched reluctance machine supplying three independent DC power buses. Each of the power buses is coupled for supplying power to a respective pair of diametrically opposite electromagnets of the magnetic bearing so as to establish multiple magnetic control axes. Multiple power controllers are each operatively connected in circuit with a separate respective power bus. The power controllers include independent power control systems each coupled to a respective pair of diametrically opposite electromagnets for independently controlling energization of each one of the pair of diametrically opposite electromagnets.
