Abstract:
A stator core (30) in a rotating electric motor (100) has: an outer core (30a) that is an annular back yoke; and an inner core (30b) in which a plurality of teeth (31) are radially disposed, the inner tips of circumferentially adjacent teeth (31) are linked in the circumferential direction by linking sections (332), and which is fitted inside of the outer core (30a). The linking sections (332) have holes (332h) that extend in the axial direction. The linking sections (332) are divided into a plurality by the holes (332h). The radial-direction width of one of the linking sections where the radial width of the linking sections is smallest is at least 1/4 and less than 1/2 of the thickness of the thin plate.
