Hello, first post here. Hoping you folks can help out an 'electronics-challenged' newb. I picked up a commercial treadmill for cheap that wouldn't run when the incline function was used. I'm interested in using the motor, which is a very nice Leeson, Permanent Magnet DC, 3hp continuous duty motor (130V, 20A) to drive a variable speed belt 2x72-inch belt grinder. Typical AC power requirements for one are less than 2hp continuous duty. My issue is I'd like to ditch the control panel and just utilize the existing speed control board, which is PWM-based and rated at 15A. That board was made by Digital Concepts, Inc. in St. Louis, Missouri and isn't as prevalent as the standard MC-60, MC-2100-type controllers used for residential treadmills. Is there a way to wire in a simple potentiometer to control the speed of the motor using the existing board? Pics of the DCI control board attached.
