Abstract

PURPOSE: To improve the dielectric strength of both main and auxiliary windings, by arranging windings in a shape of one slot for one winding while decreasing the crossing portions of each at main and auxiliary windings in an end coil portion at the opposite of the drawing side of an lead wire.
CONSTITUTION: Main winding 4 is inserted at the inner circumferential side and auxiliary winding 5 at the outer circumferential side respectively in a stator core 2, the main winding 4 at the opposite of the lead wire drawing side 1 is shaped at the inner circumferential side and the auxiliary winding 5 at the outer circumferential side, and the crossing portions of the winding 4, 5 are diminished in the coil 1 portion. In the winding arrangement of the winding 4, 5, winding inserted into slots #1∼7, 2∼6 forms one pole portion and winding inserted into #7∼13, 8∼12 two pole portions, and the winding of #1∼7 is shared with the winding of other poles. Thus, since not only the surface area of the coil 1 portion increases and the efficiency of cooling is improved but also the crossing portions of main and auxiliary both wind is lessened, probability that flaws approach is reduced, and insulating resisting pressure can be bettered.
