I made this using an Arduino for the PWM signal to the 2n3055 transistors to control the speed of a wheelchair motor. I took the breaks out of the motor to run it on 12 volt but it will run on 24 volts. It draws about 7 amps. Under load about 9 to 10 amps. I don't have a schematic for this. I just put this together one day when I was bored.
