ることを特徴とする電動機の速度制御装置。 In an electric motor speed control device that uses the output of an acceleration/deceleration circuit that increases or decreases at a predetermined acceleration/deceleration rate as a speed reference and controls the acceleration/deceleration of the electric motor by feeding back the actual motor speed, the control power goes down and the electric motor becomes idle. A speed control device for a motor, characterized in that when the control power is restored during rotation in a run state, the speed of the motor at that time is set as an initial value of the speed reference of the acceleration/deceleration circuit.
