Simple Dc Motor Speed Control Circuit Diagram. The ic tda 7274 is a monolithic integrated dc motor speed controller intended for low voltage low power applications. Here is a simple dc electric motor variable speed controller circuit that can be configured to control the sweep rate of automobiles windscreen wipers.
The speed is controlled through an externally applied varying dc voltage source. The circuit comprises a timer ne555 ic1 medium power motor driver transistor bd239 t1 high power switching transistor bd249 t2 and a few other discrete components. But if you want circuit that a good than this circuit.

Dc motor controller diagram using scr and cmos. A simple pwm motor speed control circuit with diagram and schematic for low power dc motors. Are you fed up with ordinary pwm circuits which do not provide perfect dc motor speed control especially at lower speeds. A circuit which enables a user to linearly control the speed of a connected motor by rotating an attached potentiometer is called a motor speed controller circuit.
