Good eye Bill!
I've been watching them. This motor is a big 2hp 90V job. I have one of these and I found it very difficult to get a controller that will put out 2hp at 90V. The folks at Ohio Electric were very helpful when I phoned them about these motors a while back. It seems that they were made to a customers specs rather than an over the counter consumer model. Here's what to watch for,.... You can easily get a 2hp controller but they are 2hp @180V rather than 90vdc. Many of them are dual voltage so you can run them on 110/220VAC. If you run them on 110VAC, you get 90VDC output for 1hp and if you run them on 220VAC you'll get 180VDC output up to 2hp. So, since your motor is fixed at 90vdc, you are forced to run it on 110vac. Now, you can run this 2HP motor on a 1HP controller at 110VAC but you'll only get a max of 1 hp output...not 2hp. That's what I'm doing and it works great! The newer controllers have all sorts of current protection features and it simply will not put out enough power to hurt the motor or damage the controller.
So....based on my experience with these motors, I would buy it with the idea that you'll use it as a 1hp job, and hopefully you'll find a controller that will run 2hp at 90vdc, then you can actually run it at 2 HP If anyone has a 2hp 90V controller that you wanna sell, drop me a line.
Just my thoughts,
