I want to build a DC motor speed control with forward and reverse control of the motor.
I found this circuit on the internet and not sure if its suitable. I have measured the motor under load and its 15 Amps. I wonder if this transistor is big enough or there is an alternative way of switching the motor.
To change the direction I am thinking of swopping the polarity of the motors through a relay. Is this practical?
Its to control the speed and direction of an electric child's car that I am trying to rebuild.
