    摘要: In a motor (1), a magnet (6) is configured so that four pairs of S-poles and N-poles are formed at equal angular intervals, and a stator core (8) has six salient poles (80) formed thereon. Of the plurality of salient poles (80), a first salient pole (81) having a first coil (76) wound therearound and a second salient pole (82) having a second coil (77) wound therearound are offset from each other by an angle of 112.5°. When the first salient pole (81) or the second salient pole (82) faces a position between an S-pole and an N-pole, the other salient pole faces the center of an S-pole or the center of an N-pole. The radial-direction lengths of the first salient pole (81) and the second salient pole (82) among the plurality of salient poles (80) are longer than the other salient poles (80), and the radial-direction length of the portion of the first coil (76) wound around the first salient pole (81) and the radial-direction length of the portion of the second coil (77) wound around the second salient pole (82) are longer than the radial-direction lengths of the other salient poles (80). Thus, the volume of the sound generated during acceleration or deceleration of the rotor is reduced.
