ABSTRACT:
In a stator winding method for winding conductive wires8around teeth4ato4fof a stator core4having 3n teeth4ato4fand 3n slots5ato5fby use of a bobbin machine12having three nozzles13, the slots5ato5fon both sides of the teeth4a,4d,4fin the nthwinding process are formed, in respective slot portions on the side of the teeth4a,4d,4fin the nthwinding process, so that respective depths “A” are all smaller than respective depths “B” of the remaining portions. At the final stage of the nthwinding process, the nozzles13are moved from the interior side of the slots5ato5ftoward the inner circumferential side of the stator core3and furthermore, the conductive wires8are wound around the teeth4b,4d,4fso that each gap14between the conductive wires8wound around the teeth4b,4d,4fand the conductive wires8wound around the teeth4a,4c,4eis smaller than an outer diameter of the nozzle13.
