摘要： An object is to provide a permanent magnet motor that highly reduces torque fluctuation, thereby reducing noise and vibration. The permanent magnet motor may be formed as follows: a length D of a permanent magnet 8 in a longitudinal direction is the same as or longer than a width A between sides of the magnetic pole tooth 3 in the circumferential direction in an end portion of the magnetic pole tooth 3, and a distance C between tip portions of a pair of the first slits 13a and 13b within the same pole is smaller than the width A between the sides of the magnetic pole tooth 3 in the circumferential direction in the end portion of the magnetic pole tooth 3. The permanent magnet motor, thus formed, may be characterized in that cut surfaces 12 face the first slits 13a and 13b.
