Abstract
There is provided a motor including a rotor and a stator arranged outside the rotor in the radial direction. The rotor includes a rotor core, a plurality of magnets arranged at equal intervals in the circumferential direction of the rotor core and functioning as one magnetic pole, and salient poles integrated with the rotor core, each arranged between adjacent magnets and at a distance from the magnets. The salient poles function as the other magnetic pole. A stator has a stator core having a plurality of teeth extending in the radial direction of the stator and arranged at equal intervals in the circumferential direction, and multi-phase coils attached to the teeth.
