ABSTRACT:
A motor includes a plurality of core assemblies forming three phases, and a plurality of coil windings provided on the respective core assemblies, wherein one of the coil windings is wound in a coil winding direction opposite to a coil winding direction of the coil windings on other of the coil assemblies, grip sections that are arranged in an axial direction to hold the core assemblies, and pole teeth that connect to at least two of the grip sections on both sides of the center one of the core assemblies and extend from each of the two grip sections in both directions in the axial direction. The pole teeth extending in both directions from each of the two grip sections are arranged along a circumferential direction so as not to overlap one another in the axial direction, and the at each of the grip sections is formed from a single magnetic plate.
