Hi, I took apart my grinder/polisher and adjusted a small pot in there and it lowered the speed right down which will be useful for my car as a paint flatter. Only problem is it lacks torque. I was wondering if it is possible to increase the torque. Access is ok and the project is a realistic one, perhaps unlike my car's alternator regulator. I was thinking of using a capacitor and resistor to dump large pulsed currents through the motor every tenth of a second or so to keep speed low but beef up torque. Is this practical or is a different conceptual approach needed to improve the torque? I really don't want too much speed involved. Thanks.
