    摘要： Slots (14) are formed in a stator core (15) at a ratio of two per phase per pole and winding phase portions (30) constituted by star-shaped winding units are installed in the stator core so as to line up in six layers radially. An a-phase winding phase portion (30a), a b-phase winding phase portion (30b), and a c-phase winding phase portion (30c) constituting a first three-phase alternating-current winding constitute three radially-outer layers, and a d-phase winding phase portion (30d), and e-phase winding phase portion (30e), and an f-phase winding phase portion (30f) constituting a second three-phase alternating-current winding constitute three radially-inner layers.

    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 distance between an inner joint portion located on an inner peripheral side of a stator core and an end surface of the stator core is different from the distance between an outer joint portion located on an outer peripheral side of the stator core and the end surface of the stator core.
