COMPOSITE TORQUE ROTATING ELECTRIC MACHINE

WIPO Patent Application WO/2013/179375

A1

The purpose of the present invention is to improve torque in a composite torque rotating electric machine which uses permanent magnets having a low residual magnetic flux density such as ferrite magnets. This composite torque rotating electric machine is characterized by being provided with: a stator comprising armature windings arranged at a fixed interval at multiple positions on the inner periphery; a rotor which has a permanent magnet in a cylindrical core comprising laminated magnetic steel sheets and which is arranged inside of the stator; and magnetic flux blocking units which are provided across the circumferential direction on the outer periphery of the rotor and which block the closed loop magnetic flux generated around the stator windings. The magnetic flux blocking units are provided with multiple permanent magnets, and a non-magnetic body disposed between said permanent magnets. Further, the non-magnetic body is an air gap. Further, the distance between the permanent magnets and the non-magnetic part is characterized by being smaller than the interval at which the armature windings are arranged.
