Patent number: 10848018Abstract: A stator is provided. In this stator, a stator core comprises: an outer peripheral ring part formed in a ring shape; and multiple salient pole parts protruded from the outer peripheral ring part to an inner side in a radial direction of the stator. The outer peripheral ring part comprises outer peripheral parts in a same number as multiple salient pole parts. When an outer side face of the outer peripheral part in the radial direction is an outer peripheral face, both end side portions in the circumferential direction of the outer peripheral face of one of the outer peripheral parts are respectively formed to be a curved face part in a convex curved face shape which is a circular arc shape, curvature radii of the circular arc shapes are equal to each other and their curvature centers are common when viewed in an axial direction of the stator.Type: GrantFiled: September 28, 2016Date of Patent: November 24, 2020Assignee: NIDEC SANKYO CORPORATIONInventors: Keishi Otsubo, Shinichi Utsumi, Yuji Maruyama, Hideo Shimodaira
