<P>PROBLEM TO BE SOLVED: To provide a rotor capable of increasing an effective magnetic flux. <P>SOLUTION: First to fourth rotor cores 21 to 24 of a rotor 11 are disposed along an axial direction of a rotary shaft 12. The first to the fourth rotor cores 21 to 24 have claw-shaped magnetic poles 21b to 24b alternately arranged along a circumferential direction. Respective claw-shaped magnetic poles 21b to 24b are formed so as to extend toward mutually opposite directions along the axial direction. A triangular part as viewed in the axial direction, which is formed by both circumferential end faces of the first claw-shaped magnetic pole 21b and a radial inner side face 21f on both circumferential end faces of each first claw-shaped magnetic pole 21b, functions as a flux induction part for inducing a magnetic flux of an interpole magnet 31 to a radial outer side face 21e of the first claw-shaped magnetic pole 21b, that is, an end face of the first claw-shaped magnetic pole 21b facing a stator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
