I made this video to show how I salvaged the motor and speed control from a used treadmill. With a small modification, I was able to simplify the electronics for later use as a variable speed conversion for a fixed speed motor power tool.
I removed the bulky control interface and replaced it with a 10K ohm potentiometer. (I chose a wire wound potentiometer, but a regular carbon film potentiometer would work just fine.)
I also show how you can reverse the direction of the motor and also stop and start the motor without having to constantly adjust the potentiometer.
Dear Barry
Can you share to me the circuit ?
I watched your video on treadmill and have a ? ///// I have treadmill that looks like yours. Mine don’t have 3 wires connection for potentiometer. It has 8 wires. Which wires should I try?
Can send pic. Thank Danny
