<P>PROBLEM TO BE SOLVED: To provide a rotator of a rotating electrical machine which improves cooling performance of permanent magnets and prevents partial deterioration of demagnetization resistance of the permanent magnets. <P>SOLUTION: The rotator 15 includes a rotator core 12 formed by laminating multiple annular steel plates 12a in the rotation axis direction and arranged so as to face a stator 18 in the radial direction, permanent magnets 13 arranged in the rotator core 12 so as to have a predetermined space therebetween in the circumferential direction, and a pair of annular end plates 14 arranged so as to contact both end surfaces of the rotator core 12 in the rotation axis direction. Heat transfer members 21 are arranged in the rotator core 12 so as to penetrate through the rotator core 12 in the rotation axis direction and contact the pair of end plates 14 at both ends. <P>COPYRIGHT: (C)2012,JPO&INPIT |
