Patent number: 7259488Abstract: A rotary electric machine comprises a rotating shaft rotatably supported by bearings, a rotor attached integrally with the shaft and a stator facing the rotor. The stator includes a plurality of coils arranged substantially in a circular form in a rotating direction of the shaft. The rotor includes a circular-disc rotor yoke made of a ferromagnetic material, such as iron. Depressed and raised portions on a surface of the rotor yoke facing the stator, except for the center portion, are arranged in a circumferential direction of the rotor yoke. N-pole and S-pole magnets are alternately arranged in the depressed portions. Therefore, in addition to torque generated by the magnets, reluctance torque is generated between the raised portions on the rotor yoke side and the teeth on the stator side, thus making it possible to increase the range of rotation speeds of the motor.Type: GrantFiled: July 31, 2006Date of Patent: August 21, 2007Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Shinya Naito, Hino Haruyoshi
