12 Volt Motor Speed Control Circuit Diagram. 3 easy to build speed controller circuits for dc motors are presented here one using mosfet irf540 second using ic 555 and the third concept with ic 556 featuring torque processing. They use the principle of pwm motor control mode.
Today i share with you a motor control circuit new small project. These are 12 volt dc variable speed motor controller circuit using cmos. Are you fed up with ordinary pwm circuits which do not provide perfect dc motor speed control especially at lower speeds.
We have many ways to do it.
By using this pwm circuit you can control the speed of dc fan by moving the potentiometer variable resistance. This simple circuit drives dc motors with a maximum current of 1 a and can be built with readily available components. P55n mosfet you can use any mosfet 50k potentiometer10k resistor12 volt power supplycircuit diagram. Do you want to control the speed of dc motor.
