してなる電動機の速度制御装置。In a device that controls the speed of an electric motor while controlling the phase of a thyristor for controlling power supply to the electric motor by comparing the rotation speed of the electric motor with a speed setting value, charging is controlled while being regulated by the comparison operation. It has a capacitor, a trigger element that operates at a predetermined charging voltage of the capacitor and provides a trigger signal to the thyristor, and a switching element that controls opening and closing of both ends of the capacitor in response to timing operation with an alternating current voltage of a motor. A speed control device for an electric motor, which comprises a phase control circuit for the thyristor as described above, and is configured to operate this phase control circuit with a stabilized direct current source.
