御装置。A contact switching means such as an electromagnetic contactor is interposed in the power supply circuit from the multi-phase AC power source to the multi-phase induction motor, and by switching this contact switching means, the phase rotation direction of the stator windings can be changed. In the device, the device is capable of controlling forward and reverse driving of the electric motor by means of a non-contact switching means connected in series to the contact switching means to connect and disconnect the auxiliary power supply circuit, and a non-contact switching means connected in series to the contact switching means to connect and disconnect the auxiliary power supply circuit; The present invention is characterized by further comprising a control means that causes conduction to occur later than the closing operation of the contact switching means and when the electric motor is stopped, causes the non-contact switching means to be cut off prior to the opening operation of the contact switching means. Drive control device for phase induction motor.
