Motor

摘要

The disclosure discloses a motor including a stator and a mover. The stator and the mover are arranged facing each other so as to be relatively movable via a magnetic air gap. Any one of the stator and the mover includes a yoke, a plurality of teeth, and a plurality of coils. The plurality of teeth are disposed protruding from the yoke to the magnetic air gap side. The plurality of coils are wound around the plurality of teeth. The plurality of coils include, for each phase, coil groups. Each of the coil groups includes a plurality of the coils. The coils are continuously arranged along the relative movement direction and are in-phase with each other and have the same wire diameter with each other. The coil group includes at least one the coil in which a coil width is larger than a teeth pitch.
