The time has come when I must appeal to the great philosopher warrior of the Great White North and his prophet Dewclaw. I am an unworthy retired nuclear turdherder living in the United Soviet Counties of Illinois and recently acquired at auction a great honkin’ 6100 pound Cincinnati mill that appears to have originated in Upper Canuckistan. At least that is what I am lead to believe because the motors (at least 3, maybe more) are wound for 550 VAC 3 phase. I, of course have no 3 phase available. I run my 3 phase lathe at 240 VAC using a VFD. But this 550 juice is not found South of Windsor. What insights might be shared by you, Dewclaw or any of your multitude of devotees that could help me get this beast of a mill running without hand-winding a step-up transformer from 240 to 550 then finding a suitable cold-weather VFD in Toronto? Or running an extension cord to my former power plant employer on the Bruce peninsula to tap off some metric Amps at 550 VAC! At least it is 60 Hz!
Such good advice Ave. I train a lot of young kids just out of school. I cant get over how many of them will spend inordinate amounts of time searching on their phones for wiring diagrams of circuits that are very basic and simple to figure out. You’ve got a meter, you’ve got a pen and paper, you’ve probably got a brain, use them, figure it out, you might actually learn something and it might actually stick in your head.
I installed several 100 & 200 amp 240 volt services over the years. Does not cost much more then single phase motors. Cheaper in long run to have 3 phase service rather then expensive rotary or other type phase changers. Baldor is the best motor put there.

This is all hokus spokus for me but the one lesson i did learn:
"Give er"
But we're 'Murica! We PROnounce things our way, and everyone else is wrong

9 leads are for a dual voltage motor to run 240 or 460 a 12 lead is wye delta… I feel for you trying to identify lead numbers lol been there done that
Some of your one liners are comedy gold
You need to do a open mic comedy gig
is it on the motor plate hat states 2.25ohms? or is that just a common known value in the business?
He's a goddamn rocket surgeon
We run rotary converters at work. I will have to mention the vfd drives to the boss. Thank you!
She's getting relaxed… poor old girl has NO CLUE what's ahead!
