Bruce, I have several as well as a couple of recycled electric lawn mower motors. The mower motors are rated at 1.1 HP and 4000 RPM. As an experiment I set one up with a light dimmer switch and it ran fine unloaded as a demo! I would however use a motor controller in a real world application.?

Could you give a quick rundown on removing the motor and controller from a treadmill??

Both times the treadmill was already pretty beat up, (one was already mostly disassembled, so I just removed the plastic cover on the other by breaking it off. ?

The motors were bolted on with two bolts attached to a bracket welded on the side of it. ?One was missing the controller and other electronics, so all I got was the motor.?

Finding the controller pn the other was just a matter of tracing the wires from the motor back to it for the other one; it was mounted close by the motor. the other controls were plugged into the controller board. There was also a big transformer-looking thing (although it only has twp wires, so it¡¯s just a large choke.) that I grabbed as well.

Also pretty much all of the controller boards look alike (and are easy to replace) typically look like this:?

On the second one I got a bonus, tucked in next to the controller was a manufacturer¡¯s tech sheet showing the pinout and specs of the controller :-) This also seems pretty generic; I¡¯m pretty sure I scanned it; if I remember tonight I¡¯ll post that here, since it¡¯s a useful thing to have if you¡¯re retrofitting one.

I¡¯d intended to use one on my old 8x36 wood lathe, but honestly the old 110v cooler motor on it has worked well enough that I didn¡¯t feel the need.

A note: the big heavy flywheel/pulley on the shaft DOES come off, but it¡¯s left-handed threaded. ?

And how do you identify the motor controller from the rest of the p c board?

I have two of them; takes about 15 minutes of roadside surgery with a leatherman or similar tool to yank it and the controller from one on bulky trash day :-)
