In the permanent magnet motor of the present invention, where P is an integer not smaller than one, the number of magnetic poles of a rotor (22) is set to 2P, and the number of salient poles of a stator field core (21) is set to 3P. The salient pole section (21a) of each stator field core (21) is provided with two supplemental grooves (24). A salient pole magnetic interpolar angle is 4.theta., such that two supplemental grooves (24) of each salient pole section (21a) are arranged in positions at angles of .theta. and 3.theta. with respect to the center of a winding slot (27) in the circumferential direction of the rotor. With this structure, a fundamental wave component of a clogging torque is removed and a permanent magnet motor having a low clogging torque is provided.
