<P>PROBLEM TO BE SOLVED: To provide a rotor capable of preventing an interpole magnet arranged between claw-shaped magnets formed at equal pitches in a circumferential direction of the rotor from jumping out by rotation of the rotor, with a simple configuration. <P>SOLUTION: The length of first and second interpole magnets 31 and 32 arranged between a first claw-shaped magnetic pole 11 of a first rotor 10 and a second claw-shaped magnetic pole 21 of a second rotor 20 is respectively set longer than the length of a rotor 7 in an axial direction. First and second jumping-out prevention members 51 and 52 are formed on a non-opposing surface of a first core base where the first and the second interpole magnets 31 and 32 protrude, and on a non-opposing surface of a second core base where the first and the second interpole magnets 31 and 32 protrude. The jumping-out in axial and radial directions of the first and the second interpole magnets 31 and 32 by centrifugal force is regulated by firmly fixing them in the axial and radial directions with the first and the second jumping-out prevention members 51 and 52 when the rotor 7 is rotated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
