PROBLEM TO BE SOLVED: To provide a motor allowed to be used by finding out an opening angle from one end to the other end of a suitable claw-like magnetic pole and an opening angle between one claw-like magnetic pole and the other claw-like magnetic pole in relation with a stator.SOLUTION: An angle from one end part to the other end part in a peripheral direction of an inner peripheral surface 11a of each tooth 11 arranged around a center axis O of a rotary shaft 3 is set as a first tooth side opening angle &thetas;1. An angle from one end part to the other end part opposed to each other in a peripheral direction around the center axis O of the rotary shaft 3 on inner peripheral surfaces 11a of adjacent teeth 11 is set to a second tooth side opening angle &thetas;2. An angle in a peripheral direction of each first claw-like magnetic pole 22 around the center axis O of the rotary shaft 3 is set as a first rotor side opening angle &thetas;α. An angle in a peripheral direction of each first interpole auxiliary magnet 53 around the center axis O of the rotary shaft 3 is set as a second rotor side opening angle &thetas;&bgr;. By setting the first rotor side opening angle &thetas;α within a range of &thetas;1≤&thetas;α≤&thetas;1+(2×&thetas;2), high output torque can be obtained. |
