電動機の速度制御装置。 A control signal is supplied to a control terminal interposed between an AC motor and an AC power source, and conduction occurs when the voltage of the AC power source becomes zero, and this conduction state is interrupted by the control signal. It includes a solid-state relay configured to maintain the load current until it becomes zero after the load current drops, and a control circuit whose output side is connected to the control terminal of this solid-state relay. It is configured to be able to switch between a state in which the control signal is generated on the output side and a state in which the control signal is intermittently generated on the output side, and further provided with a device that changes the intermittent interval of the control signal. A speed control device for an AC motor, characterized by:
