SCR voltage controllers have a bad reputation as an option for powering treadmill motors. This comes from using cheap SCR controllers and not using power cleaning parts like chokes and capacitors. This video shows the components needed to correctly set up an SCR voltage controller to run your treadmill motor.

A Capacitor set up in an RC circuit like I show in this video is not required. The AC and DC chokes are the important thing for providing clean power.

Another option is to run the actual treadmill motor controller and I have a video on that as well.    • Variable Speed Power Supply, Treadmil...
