摘要： An alternator is capable of preventing a short circuit at a coil end, improving an ability of cooling a stator winding assembly, and reducing noises. A multi-phase stator winding of the alternator has: a plurality of joint portions where a distal end extending in an axial direction of a first conductor portion drawn out from a first layer in a slot and a distal end extending in an axial direction of a second conductor portion drawn out from a second layer in a slot located a predetermined number of slots apart in a circumferential direction are connected outside the slot on an end surface side of the stator core; and a coil end where the joint portions are disposed in a plurality of rows in the circumferential direction. The joint portions are set apart by half a slot from a diametrical line in a circumferential direction.

摘要： 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.
