<p><P>PROBLEM TO BE SOLVED: To provide a motor which can contribute to high output by suppressing occurrence of magnetic saturation. <P>SOLUTION: A rotor 11 includes a rotor core R consisting of first and second core members 21, 22 having a first claw-shaped magnetic pole 21b and a second claw-shaped magnetic pole, respectively, and an annular magnet 23 interposed between the first and second core members 21, 22 in the axial direction, and magnetized in the axial direction so as to make the first claw-shaped magnetic pole 21b function as a first magnetic pole and the second claw-shaped magnetic pole as a second magnetic pole. The axial length Hr of the rotor core R is set longer than the axial length Hs of the armature core 7 of a stator 6. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
