EZ-Trak DX servo motor rating, ca. 1980's

[cncsnw]

A customer sent the attached picture of a servo motor data plate. I do not have access to the machine right now, but am hoping to find out the basic electrical ratings of this motor.

It is from a Bridgeport EZ-Trak DX system. Customer says early 1980's vintage.

As far as I can read, it is an Indiana General motor, model 4020D-??C.

Does anyone here know approximately the max voltage, continuous current, and/or peak current ratings for this motor?

Bridgeport started selling EZTRAK SX in 1992 followed by the DX a couple of years later. Before that they were made by Southwestern Industries in California. The SX and Dx used SEM motors most of their length of production.

Thanks. I thought the customer said "EZ-Trak SX", but looking back at my notes he just said it was a Bridgeport with a Prototrak. Perhaps someone installed an earlier vintage Prototrak on this machine as a retrofit....

Anyone know about Prototrak controls using Indiana General DC servo motors?
