摘要：
In a fan motor, there are provided protruding portions provided integrally with a base member so as to face a magnet and protrude toward the magnet, and openings facing the magnet, in the base member made of magnetic material. As to the positional relation between the protruding portions and the openings, when the protruding portions are positioned corresponding to centers of the magnetic poles, the openings are positioned corresponding to boundaries between the magnetic poles. As to the positional relation between the protruding portions and the coils, when the protruding portions are positioned corresponding to centers of the magnetic poles, both ends of the coils are positioned corresponding to positions other than the boundaries between the magnetic poles.
