の速度制御装置。A motor speed control device that controls the speed of an electric motor while avoiding a specific speed range includes a speed setter that sets a normal speed standard, and a specific upper limit speed setter that sets the upper limit speed of the specific speed range. , a specific lower limit speed setter that sets the lower limit speed of the above time constant speed range, and when the set speed of the above normal speed setter falls within the above specific speed range, the speed standard is switched to the above specific upper limit speed or specific lower limit speed. A speed setting switching circuit compares the set speed of the normal speed setting device with the specified upper limit speed and the specified lower limit speed when the speed is within the specified speed range, and adjusts the specified upper limit speed and the specified lower limit speed according to the ratio of the difference. 1. A speed control device for an electric motor, comprising: a time ratio adjustment circuit that adjusts a time ratio of alternately inputting the following values as a speed reference.
