の速度制御回路。The fluctuation in the current flowing through the DC motor in response to the fluctuation in the rotation of the DC motor is extracted as an error voltage, and the drive current supplied to the DC motor is varied in accordance with the error voltage, so that the rotational speed of the DC motor becomes constant. In a speed control circuit for a DC motor, the main part of which is a semiconductor integrated circuit, the DC motor and the A speed control circuit for a DC motor, which is provided with a diode that bypasses the integrated circuit so that no current flows when the power supply of the integrated circuit is reversely connected.
