Fortunately, the copy of Drawing EE-61 called out on this plate and supplied with this machine has been preserved .

My 3-phase rotary converter generates 220V, not 440, so I had initially planned to remotor this machine for single phase. It's a NEMA-48 frame motor, which is relatively common. That's probably what I ought to do, actually.

However, two other machines acquired soon after also use 440V 3-phase, and one of them cannot really be remotored. So now I've got a 6 kVA 220v to 440V transformer, and I plan now to run these machines at 440 with their original motors.
