Abstract
The wire 30 forming the stator winding 20 includes the in-slot portions 40 to be disposed in the slots 14 and 15 of the stator core 12 and the turned portions 42 connecting the in-slot portions 40 disposed in the circumferentially different slots 14 and 15. The turned portions 42 formed on axial opposite end sides of the stator core 12. The crank portion 44 which does not twist is formed at substantially the center of the turned portion 42. Steps are fanned at sections of the turned portion 42 which protrude outside the stator core 12 from the slots 14 and 15. Further, the turned portion 42 of the wire 30 also has two steps 48 formed between the substantially central crank portion 44 and each of the steps 46 formed at the protruding sections of the turned portion 42.
