Abstract:
1. An alternator for a vehicle comprising: a rotor; a stator disposed around said rotor, said stator including a stator core in which a plurality of slots are formed, the stator core having ends opposed to each other in an axial direction of said stator; and a stator winding wound through the slots of the stator core, said stator winding being made up of a plurality of conductor segments, each of the conductor segments including an in-slot portion disposed in one of the slots and an end portion extending from the in-slot portion outside one of the ends of the stator core, the end portions being broken down into at least a first and a second group, each of the end portions of the first group being connected to one of other end portions of the first group through a first joint, each of the end portions of the second group being connected to one of other end portions of the second group through a second joint, each of the first joints being elongated in the axial direction of the stator core to have a longitudinal sectional area which is 1.5 times or more greater than a transverse sectional area of the conductor segments.
