A stator core (2) includes an inner ring core (3) composed of a plurality of teeth (6) arranged in the circumferential direction and a connection portion (7) connecting inner circumferential portions of the plurality of teeth (6); and an outer ring core (4) to be joined to an outer circumferential surface of the inner ring core (3). Slots (5) of the stator core (2) each have a circumferential direction width (a) on an inner circumference side smaller than a circumferential direction width (b) on an outer circumference side. A stator coil (10) composed of conductive coils (11) including a plurality of slot accommodated portions (12) and a plurality of coil end portions (13) connecting the slot accommodated portions (12) is inserted and placed in the slots (5) from an outer side in the radial direction of the inner ring core (3). |
