Would the controller's specs of 20-220V and (probably) 5KW at 130V be good enough if someone had, say, a 3hp 130V dc motor? Next, remove the belt from the lathe. Visual Explanations: https://www.youtube.com/watch?v=FSMGOP01ulw. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!). ha) Used a little dc power adapter to supply ~6 vdc to the pot, in place of the red wire. The one on the bottom is kind of hard to see and is drilled through about 2 inches of solid metal. Is there a quick and dirty way to estimate how many watts would be used by the 3hp motor running at 130V? Posts: 744. Once the belt is removed, you can begin working on the conversion. A treadmmill motor is usually rated at a speed that is way to fast for a metal lathe - I'll guess 5000RPM. Torch Posts: 1669 Joined: Wed Mar 17, 2010 12:58 pm . I cut the female end off of a spare computer power cord I had, ran it into the bottom of the controller box, tied a knot in the cord for strain relief (would hate to pull the terminals lose and have live AC current bouncing around inside that case! I assured him it would not get thrown away. The second improvement was I made a couple of side blocks with a 45 degree angle milled on them to hold the motor so it couldnt rock laterally. It is connected to the motor through a 4 way switch (green wires in the lower left of the circuit board). I think such rocking is likely how the original motor mount got broken. I did a search on (variable, controller, controler) motor and bid on this one. I also appears to be 2-3X bigger in size/volume of any treadmill motor. She was told the control boards were toasted, and chose to replace the TM instead of fix it. What does the variable speed control on a lathe do?
