Variable Speed Treadmill Motor Electrical Conversion

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 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.
