Abstract
A stator for a vehicle ac generator includes a stator core having a plurality of slots and a star-connected stator winding. The stator winding has a plurality of sets of U-shaped large and small segments. The large segment has a pair of in-slot portions respectively disposed in the radially outermost slot-layer and radially innermost slot-layer. The small segment has a pair of in-slot portions respectively disposed in the radially outer middle slot-layer and radially inner middle slot-layer. Three output terminal ends respectively extend from the small segments, and three neutral terminal ends respectively extend from the large segments.
