Abstract:
A permanent magnet electric machine (PM machine) for a vehicle or other system includes a rotor assembly, fixed permanent magnets, a stator, an actuator, and one or more repositionable/moveable flux-shunting elements. The flux-shunting element is repositioned to control flux at specific operating points of the PM machine. The rotor assembly has a rotor coaxially surrounding and coupled to a rotor shaft. The permanent magnets are mounted to or in the rotor, and the moveable flux-shunting element is positioned between the rotor shaft and a respective one of the permanent magnets. Inboard and outboard ends of each respective permanent magnet may be oriented toward the rotor shaft and stator, respectively. The actuator selectively positions the moveable flux-shunting element at one or more operating points of the PM machine to vary reluctance in a magnetic circuit formed by the stator and rotor assembly.

Claim (Index 13):
A vehicle comprising:\n drive wheels; a transmission having an input member and an output member, the output member being connected to the drive wheels; and a permanent magnet electric machine (PM machine) coupled to the input member and configured to deliver motor torque to the input member, the PM machine having:\n a rotor assembly having a rotor shaft, a rotor coaxially surrounding and coupled to the rotor shaft, a plurality of fixed permanent magnets each of which is mounted to the rotor and has a respective inboard end and outboard end, and a moveable flux-shunting element positioned in the rotor; \n a stator circumscribing the rotor assembly to form a magnetic circuit therewith, wherein the inboard and outboard ends of each respective permanent magnet of the plurality of fixed permanent magnets are oriented toward the rotor shaft and the stator, respectively; and \n an actuator configured to selectively position the moveable flux-shunting element of the PM machine to thereby vary a reluctance in the magnetic circuit at one or more speed and torque operating points of the PM machine.
