Kind Code:

A1

Abstract:

A stator core (2) which is provided with: an inner ring core (3) which comprises, a plurality of teeth (6) disposed in the circumferential direction, and a connection section (7) which connects the inner peripheral sections of the plurality of teeth (6); and an outer ring core (4) which is capable of joining to the outer peripheral surface of the inner ring core (3). Slots (5) in the stator core (2) are formed such that the circumferential direction width (a) of the inner peripheral sections is less than the circumferential direction width (b) of the outer peripheral sections. In addition, stator coils (10) are inserted into the slots (5) from the outside of the inner ring core (3) in the radial direction, said stator coils comprising conductive coils (11) that are provided with a plurality of slot housing sections (12), and a plurality of coil end sections (13) that connect the slot housing sections (12).
