ABSTRACT:
The stator of an electric rotating machine includes a stator core having slots formed therein along a circumferential direction thereof, and a stator winding formed by conductive wires wound on the slots. The stator winding includes in-slot portions accommodated in the slots and turn portions each of which connects each adjacent two of the in-slot portions outside of the slots. Each of the turn portions includes a first turn portion formed with M1steps (m1being a positive integer) extending along axial ends of the stator core, and a second turn portion formed with m2steps (m2being an integer larger than m1) extending along the axial ends.
