Proportional controller for motor speed provides full 0- to 100-percent linear control of durations of motor-driving pulses. Controller uses commercially available LM3900 integrated circuit, which requires only single supply voltage of 4 to 30 V. Control voltage provided by adjustable potentiometer or by external source of feedback information such as motor-speed sensing circuit.
