Abstract
Provided is a stator that can easily attach a coil to a tooth and that can reduce concentration of stress generated in the core during operation. The stator includes a plurality of divided cores aligned in a circumferential direction. Each divided core includes a tooth, and a divided back yoke extending from an end on a radially outside of the tooth to a first circumferential side. A radial width of the divided back yoke is smaller than or equal to a circumferential width of the tooth. A connecting surface is arranged at an end on a second circumferential side of the divided yoke, the connecting surface being a plane or a convex surface extending from a side surface on the second circumferential side of the tooth to an outer circumferential surface of the divided back yoke.
