Abstract
A stator includes four split cores arranged in the circumferential direction. Each split core includes a yoke including a pair of joint parts, and a tooth. The shape of an end of the tooth is asymmetrical. An angle θ1 (degrees) formed by a side surface of the tooth and a side surface of the yoke on the inner side in the radial direction of the stator satisfies 90 degrees<θ1<180 degrees.
