Patent ID: 8610326

Claim:
A stator comprising: a cylindrical stator core which has a plurality of slots arrayed in a circumferential direction of the stator core; and a stator winding which includes in-slot portions disposed in the slots of the stator core and turned portions connecting the in-slot portions outside the slots, the in-slot portions being arrayed in each of the slots in a form of multiple layers aligned in a radial direction of the stator core, the stator winding having a length made up of a first winding and a second winding, the first winding being defined by a portion of the stator winding which is closer to an end of the stator winding which is to be connected to an external, the second winding being defined by a portion of the stator winding which is farther from the end of the stator, wherein the stator winding is a three-phase winding made up of a first-phase winding, a second-phase winding, and a third-phase winding, and wherein the second winding includes the in-slot portions which are placed in all of the slots for the first-phase winding and the second-phase winding except one of the slots, and each of which is laid at least in the form of an outermost layer that is one of the layers placed most outwardly in a corresponding one of the slots in a radial direction of the stator core.
