Build a dc motor speed controller circuit written by swagatam o edited by lamar stonecypher o updated 11 23 2011 ordinary circuits incorporating just a single 555 ic to achieve dc motor speed control may be quite easy to build but do they really do the job efficiently. Pulse width modulated pwm controller for 12 volt motors this electronic controller is designed to allow a user to vary the speed and power output of a typical 12 volt motor such as a fuel pump water injection pump or cooling fan. A simple dc motor controller circuit using ne555 is shown here many dc motor speed control circuits have been published here but this is the first one using ne555 timer ic in addition to controlling the motors speed its direction of rotation can be also changed using this circuit.
