PURPOSE:To improve the workability of coil winding wirings by simplifying a starting coil and an auxiliary coil, thereby simplifying the coil configuration. CONSTITUTION:A starting coil 4A and an auxiliary coil 5A which have different space at 90 deg. of electric angle from a main coil 3A are connected in series with each other, a phase advance condenser 7A is connected to them, is connected to a power source 1A together with the coil 3A, and a start switch 6A which connect the coil 4A directly to the power source 1A only at the starting time is provided. The coil 4A is respectively wound on N- and S-poles of the coil 3A to be wound on 2 poles of 1/2 of 4 poles, and the coils 4A, 4A are spaced at a pitch corresponding to 1 pole. The coil 5A is wound only on the other 2 poles, and the coils 5A, 5A are spaced at a pictch corresponding to 1 pole. |
