Hello, I was checking out a couple of air bearing spindles on ebay and was wondering if anyone had any idea of how they were wired for the motor and encoder. The first one I was looking at was labeled "AIR BEARING TECHNOLOGY AIR SPINDLE 85-90 PSI CHUCK 55-60 PSI S/N 3175-82" and has the black cover, the other is labeled "DOVER INSTRUMENT DMM AIR BEARING" and has the black and grey case. My google search skills aren't yielding any results so any assistance would be greatly appreciated.
