Abstract
A motor includes a plurality of tooth bodies extending from a rotor core. A pole shoe extends from an end of at least one tooth body at opposite sides where both sides of the pole shoe have a curved outer part opposite to each other and asymmetric to each other in that a radius of curvature of the curved outer part of the one side of the pole shoe that is in a rotational direction of the rotor has a smaller radius than a radius of curvature of the other side of the pole shoe that is not in the rotational direction of the rotor.
