The largest single phase motor I have seen is 7.5 hp. A three phase motor is simpler and has less parts. But you can use a three phase motor with single phase input with a derated VFD.

I knew it could be done but didnt know what was needed to make it work...The elv guy says they always send them out 3 phase motors...but maybe they have to send them right back..stickboy1375 said:What do you think?

Haven't seen single can 3 phase transformers around here in a long time. POCO uses three single phase in a bank. Saves on inventory, I guess.eric stromberg said:True, but they could also start using three phase transformers that are mounted in a single case. Three primary bushings. I have a dream...

They are equipped with a control to prevent phase reversal... Safety feature...boater bill said:I was told by an old-timer that all of the traditional style elevators used 3-phase so they would never run backwards.
