Abstract
A stator core is a stack body of plural plates. Each plate includes an annular back yoke part, plural top-connected tooth parts, plural top-separated tooth parts, plural magnetic path parts and plural top open parts. The top-connected tooth part and the top-separated tooth part protrude from the back yoke part in a radial direction. The top magnetic path part connects top ends of two top-connected tooth parts. The top open part is open to a rotor side at both sides of the top end of the top-separated tooth part. The stator core includes a back yoke, plural teeth, plural partially-connected parts and plural open parts. Each partially-connected part is formed of plural top magnetic path parts and top open parts, which extend in an axial direction. Each open part is formed of only the plural top open parts, which extend continuously in the axial direction.
