Abstract

PURPOSE:To effectively stabilize the controlling operation of a controlling circuit for a motor by controlling a switching element inserted into positive and reverse direction rotating coil circuit of a motor to be controlled with a photo coupler circuit and intermittently firing the photo coupler in response to the speed of the motor to be controlled. CONSTITUTION:Switching elements TR1, TR2 are respectively inserted into positive and reverse direction rotating coil circuits of a motor M to be controlled, and are respectively controlled by photo couplers PC1, PC2. The rotating speed of the motor M is detected by a speed detector. The photo couplers PC1, PC2 are intermittently fired in response to the outputs of a start switch and a tachometer generator, and the motor M is controlled.
