直流モーター用速度制御回路。 A DC motor having an FG signal generation means includes an edge detection section that detects an edge of the FG signal from the FG signal generation means and generates a pulse synchronized with the edge generation, and an edge detection section that supplies an applied voltage to the DC motor. A pulse generating means that outputs a pulse after the period of the FG signal becomes longer than a predetermined value as the rotational speed of the DC motor decreases when the DC motor is cut off; energization signal generation means for obtaining an energization signal that is at a high level and becomes a low level in response to an output pulse from the edge detection section; and a voltage supply means for supplying an applied voltage to the DC motor only when the energization signal is at a high level. A speed control circuit for a DC motor, comprising at least the following.
