Abstract:
Systems and methods for constructing permanent magnet electric motors in which rotors have magnetically permeable end rings that are active for torque production. In one embodiment, a rotor section has a set of flat, generally annular laminations stacked on an inner rotor sleeve, with a pair of end rings positioned at opposing ends of the lamination stack to secure the stack. One or both of the end rings is made of a magnetically permeable and highly resistive material such as a soft magnetic composite, so that the end ring(s) actively produce torque during operation of the motor without significant increase in core loss at end rings. A set of permanent magnets are installed in or on the rotor core formed by the laminations. These magnets or other magnets may be positioned to axially overlap with the end rings and aid active torque production by the end rings.

Claim (Index 12):
The apparatus of  claim 11 , further comprising a plurality of magnets that are mounted on the end ring.
