Abstract
An automotive alternator has a stator winding that is made up of a plurality of U-shaped conductor segments wound through slots in a stator core. Each of the U-shaped conductor segments is connected at one end thereof to an other end of one of the U-shaped conductor segments through a joint. Some of the joints are each elongated from tips of connected two of the conductor segments in an axial direction of the stator core to have a longitudinal sectional area much greater than a transverse sectional area of the conductor segments and function as radiator fins to dissipate heat from the stator winding.
