PROBLEM TO BE SOLVED: To provide a motor capable of making a balance of cogging torque proper.SOLUTION: A motor 11 is configured in such a manner that the ratio between a pole number and the number of slots is 2:3 when the pole number of a rotor 21 is set at 2n (where n is a natural number) and the number of the slots 17b of a stator 16 is set at 3n. When a core base of a rotor core 32 is arranged on the side of a yoke housing 13 with respect to a core base of a rotor core 31 in an axial direction, a groove part 39 is provided in a central part of a claw-shaped magnetic pole 32b of the rotor core 32. |
