Last winter I picked up some large servos and a set of Rutex R2020 drives for my old Bridgeport Boss machine. I had intended on getting them onto the mill right away, then got busy with work and so that project went on the back burner. Anywho, The motors in question are big. They are Japan Servo DLs140s1-01, the label also states voltage constant of 13.9mV/RPM. It was my understanding that DC servos should be run to about 3500 rpm max, with that I am under the impression that I should be pushing a little over 48 volts into them. Let me know if that sounds about right to anyone else. Now I also need to figure out how much current these should consume. If anyone has any idea how I can go about figuring that out please let me know. The mounting flange on these is about 5.5 inches square and the body is that same diameter, so these are pretty fat motors. They came off of an older robot arm.
Thank you in advance.
