What calculations could I use to figure out the voltage and current specs on these motors? I am trying to figure out what voltage to make the power supply and which drivers to get.

This is pretty much the only specs I will ever be able to get on these motors. I can't find any calculations on the net to derive a voltage and current rating for the motors so I can build a powersupply and order drivers. It took me a month of pestering Fanuc to even get them to finally fax me these specs. This project is turning into a nightmare just because of no specs on these motors.
