Abstract

PURPOSE:To accelerate a rotary magnetic field smoothly by a method wherein in accompany with a semiconductor switching element is driven to conduct a stator wiring by an oscillating frequency signal in a oscillating circuit, a rotary speed is detected to positive feed back to the oscillating circuit. CONSTITUTION:The oscillating frequency signal in the oscillating circuit 2 is divided into 3 phase signal in a counting circuit 3, and supplied to a driving circuit 4, based upon the output thereof transistors 1u, 1v, and 1w are drawn and conduct to stator wirings U, V and W of motor. On the other hand, the conductor electromotive voltage induced at stator wirings U, V and W is detected in the detective circuit 5 by the rotary of a rotor and took out as the speed signal and positive fed back to control to the feed back circuit 2 through the feed back circuit 6. Accordingly, since it oscillates in the low frequency at the starting time and the frequency thereof becomes sequently highly, it can be accelerated smoothly in spite of an inertia is large, thus the starting failure can be prevented.
