Abstract:
A permanent magnet electric machine (PM machine) includes a rotor with rotatable magnets and a stator defining an air gap with the rotor. An actuator rotates the rotatable magnets at predetermined operating points through an angular distance sufficient for changing magnetic pole orientations of the rotatable magnets, and thus modifies magnetic flux linkage with stator windings across the air gap. Fixed magnets may be arranged around a circumference of the rotor. The actuator may be actively or passively driven. Flux-shunting elements are optionally disposed in the rotor to further modify the flux linkage. A gear set connected to torque transfer elements may be driven by the actuator to rotate the rotatable magnets. A vehicle includes drive wheels, a transmission, and the PM machine. A method controls magnetic flux linkage in the PM machine noted above.

Claim (Index 11):
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, and a plurality of rotatable magnets each of which is connected to the rotor and has a respective north-south magnetic pole orientation; \n a stator separated from the rotor by an air gap, and having a stator winding; and \n an actuator configured to selectively rotate the plurality of rotatable magnets, at one or more predetermined operating points of the PM machine, through an angular distance sufficient for changing the respective north-south magnetic pole orientations and thereby modifying a level of magnetic flux linkage with the stator windings across the air gap.
