We don't know the voltage, but at 110v that would be 150 amps, at 220v it
would be 75 amps, 220v 3ph about 50 amps, 440v 3 phase about 25 amps, and at
575v 3ph 15 amps.
Rough but quite likely close guesses...
Not bad guesses .... 230v @ 42, 460v @ 21, 575v @ 17
As far as I know no one, made/makes a 120volt or 230volt single phase motor
BTW at 460v you can run it on a 40 amp breaker and 10 gauge wire!
Of all the parts 'n pieces at work the Yates No. 1 and a
Crescent band saw (24"ish) are my two favorites. OK, they
are the most vintage. My favorite 'chine is the CNC router.
Anyways, one of these days I need to snap a shot or two.
Direct drive is what it said, I think. Somewhat different, basically meaning no

The two-high rolling mill at the Oregon Steel plant in California
had a 10,000hp DC direct-drive motor driving it. As I recall, the
rationale for that was that it was simple to reverse the motor to
run the mill rolls in both directions.
