Abstract
In a vehicle AC generator, a plurality of conductor segments having connection-ends is connected to form a stator winding. Each pair of the connection-ends is welded to each other side by side to align in a radial direction thereby forming a ring of the connection-ends disposed at equal intervals on an end of the stator core. Each pair of the connection-end has a recessed portion for preventing a welded portion of the connection-ends from swelling out of the recess in the circumferential direction.
