Abstract
In a stator of a vehicle AC generator, each of stator slots has a circumferential parallel walls and a radial wall opposite a slot-opening. A stator winding has a plurality of radially aligned in-slot portions fitted in each of the slots at the circumferential sides thereof to form a central gap at the radially central portion of the in-slot portions. The central gap provides each of the in-slot portions with spring-back force against the slot-opening. Thus, slot-openings are hermetically closed, and the teeth are prevented from being vibrated by stator winding.
