Document Type and Number:
WIPO Patent Application WO/2018/190062
Kind Code:
A1
Abstract:
A stator core of a dynamo-electric machine has an annular outer core that is a back yoke part, and an annular inner core that is fitted inside the outer core. The outer core has a plurality of V grooves that open to the inner-circumference side. The inner core has a plurality of teeth disposed a in radial formation. In the plurality of teeth, the inner-circumference sides are linked to each other, and a plurality of slot parts are formed by the side surface of each adjacent tooth.
