CNC Lathe Build. Need servo data

[Cadillac STS]

I am putting together the servo drives for my lathe build. I got these brushed servo motors in a lot with other things. I can’t find the data sheet for them.

Does anyone know where I could get the voltage information?

I see that they were built 50 miles from my place. Did you try to call?

Phone number is disconnected.

Is the place still there and operating? Is the name still MCG? I think I saw they were bought by Ametek?

Based on a quicky eBay trolling, I'd bet those are 90v servos.

Compared the size/torque/amps to similar motors with later data plates (that have the voltage listed) and the (shorter) 60V models have around 38oz-in of torque with twice the amps.

The 50oz-in at 1.99A means the voltage is certainly higher than the 60V models. Most of the ones listed are 24, 60, 90, and 170VDC.

I contacted the seller and he gave me this spec sheet.

He said all the parts came together and it was pulled from a working machine. The toroidal transformer and bridge rectifier have two taps one 24 volt and one 50 volt.

Why wouldn’t the spec sheet list voltage?
