Treadmill motor wiring
« on: August 24, 2016, 11:44:47 AM »
So my motor on my minimill is on it's way out. In anticipation, I picked up a treadmill motor. The motor says on the side, that it is a permanent magnet DC motor. It has 4 wires coming out of it. 1 red, 1 black and 2 blue.

I also have a KBLC-19PM controller that I bought. It was originally purchased to replace the stock controller.

From what I have been reading, the KBLC-19PM can be used with the treadmill motor.

I am lost on the wiring for this thing. What are the blue wires for coming from the motor? How would I wire this thing up?

Ok. After some time searching last night, I didn't find much to help me. But, I found this today.

The blue wires are to connect a thermal breaker.

OK, so it's +DC to the blue, blue to the red, -ve dc to the black.

I would disregard the thermal sensor(blue) wires. I've had a treadmill motor running my X2 mill for 3 years . I removed the blue wires at installation and never looked back. No problems!
I also used the treadmill's MC-60 controller.

Trouble with that approach is that motor could re-start without warning when it cools down.  It is preferable to wire the thermal switch into the stop chain of a control circuit. 
This will also reduce current through the thermal switch, not sure if the switch is rated for full load current or is just design for control signals.

Good point David..
