摘要： PURPOSE:To prevent a boosing speed at the time of acceleration by a method wherein in the case of a positive characteristic heat sensible element is interposed in an auxilary wiring of small number pole, and it is changed from the multi poles to the small number poles, the current in an auxiliary wiring is enlarged temporarily. CONSTITUTION:A starter wiring of a single-phase induction motor is composed of 2 poles W2 and 4 poles wiring W4, a phase advance capacitor C4 is connected to the auxiliary wiring W4A of 4 poles wiring W4, and a phase advance capacitor C2 and a series circuit of the positive characteristic heat sensetive element PTC and a capacitor C1 are connected to an auxiliary wirng W2A of the 2 poles wiring W2. Accodingly, when a switch S2 is ON, and the 2 poles wiring W2 is switched, at first the resistance at PTC is low and a large current flows in the auxiliary wiring W2A by the capacitor quantity of C1+C2, due to the resistance at the PTC becomes high and the current returns to a normal value it will not loose a speed and the secured accelaration can be obtained even though in the case fo the negative torque is large.
