<P>PROBLEM TO BE SOLVED: To improve reluctance torque in a rotary electric machine where the torque is generated. <P>SOLUTION: In the rotary electric machine, a conductor plate 11 is arranged as a magnetic shielding body generating magnetic flux which weakens electromagnetic force (negative electromagnetic force) acting in a direction where rotation of the rotor 2 is prevented on an anti-rotor rotation direction side portion of each magnetic silent pole portion 5 which the rotor 2 has. When eddy current occurs in the conductor plate 11, the magnetic flux is generated in a direction where the magnetic flux generated by energization to stator winding 7, which is generated between a stator 3 and the rotor 2, is prevented. Thus, the magnetic flux at the periphery of the conductor plate 11 is deteriorated and the negative electromagnetic force is deteriorated. Since the negative electromagnetic force can be weakened, the torque can be improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
