Abstract
A stator of a vehicle AC generator includes a stator core having a plurality of slots and a plurality of phase-windings formed of a plurality of conductor members inserted in said plurality of slots. The stator winding has first and second coil-end groups formed of portions of the conductor members respectively extending from the slots to opposite ends of the stator core. Each of the phase-windings has a lead-end which partially covered with an insulation member and extends along the first coil-end group to be connected to one another. The insulation member is bonded to the first coil-end group.
Claims14
A stator of a rotary electric machine comprising:
- a stator core having a plurality of slots;
- a plurality of phase-windings respectively formed of a plurality of conductor members inserted in said plurality of slots;
- wherein
- said stator winding has first and second coil-end groups formed of portions of said plurality of conductor members respectively extending from said plurality of slots to opposite ends of said stator core,
