If you go to
www.globalspec.com, you can register and get access to a wide variety of motor options. Many of the companies listed there make custom motors, and could probably match our specs for gearing, output shafts, windings, etc. They might even be able to make something very similar to (or better than) the Ametek 99. I found companies listed there scattered across the US and Canada. Don't know what prices are like, but this might be a valuable resource.
