24v Dc Motor Speed Controller Circuit Diagram. It is easy and uses a few components that ic digital and transistor driver as main. Here is a simple dc electric motor variable speed controller circuit that can be configured to control the sweep rate of automobiles windscreen wipers.
You have a choice whether to use the same dc voltage to both the motor and the kit or to use a different voltage for the motor eg. One push button will rotate motor clockwise and other will rotate it counter clockwise. In this project we control direction and speed of a 24v high current motor using arduino and two relays.
Furthermore this motor speed control.
Install the 555 ic on the breadboard. The method of pwm is explained here. Install the 555 ic on the breadboard. The circuit is designed for dc 12v motor and has been tested with.
