I went with the Model ZY6812 24vdc 150w? motor, cheap on? EBay. A 24vdc power supply, these are used to power LED s and a 24v variable power supply all from EBay and cheap, it still works great. I have posted about it a long time ago, here is a link to my many photos of the construction.

It's been a while since I did a project using a KB drive, but I remember that some units could be run on either 120V or 240V.? When operated on 120V you got a 0-90V output, and on 240V you got a 0-180V output.? You need to be sure your motor matches that voltage rating.? A regular 12VDC or 24VDC motor won't work that well, you'd have to limit yourself to the bottom 10%-20% of the drive output.? (Anything over that and the magic smoke would be let out of hte motor.)? That being said, if you've got the right motor to go with the drive then you've got yourself a nifty little set-up that'll run reliably for years.? I've taken out 20-30 year old industrial equipment that had KB drives in them and the drives were still running strong.? The mechanicals were completely worn out, but the drives were still good.
