PROBLEM TO BE SOLVED: To provide a motor capable of reducing the volume of sound which is generated when a rotor is accelerated or decelerated.SOLUTION: In a motor 1, a magnet 6 is formed with four couples of S poles and N poles and in a stator core 8, ten salient poles 80 are formed at equal angle intervals. Among the plurality of salient poles 80, one of two salient poles 80 dislocated at 72° in the angle position is a first salient pole 81 around which a first coil 76 is wound and the other is a second salient pole 82 around which a second coil 77 is wound. Regarding the first salient pole 81 and the second salient pole 82, a radial dimension is longer than that of the other salient poles 80. A radial dimension of a portion where the first coil 76 is wound around the first salient pole 81 and a radial dimension of a portion where the second coil 77 is wound around the second salient pole 82 are longer than the radial dimension of the other salient poles 80. |
