SKEMA : DC Motor Controller Circuit Using 741 Op-Amp
This DC motor controller circuit using a 741 operational amplifier operating as a voltage follower where its non inverting input is connected to the speed and rotation direction of a potentiometer VR1. When VR1 is at mid position, the op-amp output is near zero and both Q1 and Q2 is OFF.When VR1 is turned towards the positive supply side, the output will go positive voltage and Q1 will supply the
