Abstract
The inductor type rotary motor of m-phase (m represents an integer of 2 or more) includes a stator in which distal ends of teeth are circularly disposed, and a rotor having an inductor tooth that faces each of the distal ends of the teeth through a constant gap. The stator includes k·m teeth (k represents an integer of 1 or more), at least one permanent magnet is disposed at each of the teeth, and adjacent permanent magnets, which belong to teeth adjacent to each other, are disposed in such a manner that different polarities face each other.
