Abstract:
A stator is provided. The stator includes a yoke part of an annular shape, tooth winding portions that protrude inward from the yoke part and around which an electric wire is wound, and a tooth end portion formed on an inward side of the tooth winding portion. The stator is formed by stacking steel plates in a direction corresponding to a rotational axis of a motor. The tooth winding portion is formed by stacking the steel plates having different shapes such that at an end portion in the stacking direction, thickness of the tooth winding portions gradually decrease toward the end portion in the stacking direction, and the yoke part and the tooth end portion include protruding portions formed by stacking the steel plates, such that the protruding portions protrude from the tooth winding portion in the stacking direction.
