Abstract
In a connection portion of a stator winding, conductor wires extending outward from a slot pair separated by a predetermined number of slots are joined such that end portions of conductor wires extending outward from addresses of the slot pair separated by three or more addresses are joined together (a distant-address joint portion), and end portions of conductor wires in the slot pair separated by two or less addresses are joined together (a near-address joint portion). The distant-address joint portion is offset in a circumferential direction relative to the near-address joint portion.
