Now I could be talking out the top of my head here, but if a motor is designed for star/ delta starting, it is effectively dual voltage. As most, if not all big motors use star/ delta, then the answer to your question is, they just get bigger! They will be three phase of course, whichever voltage they're running at.
Why do you want to know? Is it an inverter question?

Yes it is an Inverter question.
Need a bigger Compressor and looking about they seem to jump from 30CFM straight to 60+CFM. 30CFM is too small and going to 60+ all the motors are look to be wound for 415v only. At 11Kw, now I can get hold of a 15kw inverter for peanuts but it's 415v>415v
I'm a bit lost, to know what to do
Don't know a great deal about this so looking for the collective wisdom

You get big spindle motors, like 25hp continuous[220 3φ].
A 415 inverter is going to be 3φ isn't it?
I have a 15kva transformer, jap machines are often supplied[so i am told] with 220V, so they supply transformers with them[that's where my table/transformer came from].

Shox, my initial advice would be to talk to the tech dept at Brook Crompton motors and see if any of their range will run on 240v, and generally to chat about what you're trying to do. I'm sure they'll be helpful.
You might have problems though getting a 240v1ph to 240v 3ph inverter of a suitable size or price, and a suitable current supply. Most 415 inverters are 3ph to 3ph anyway, and as you say, cheap as chips.
Me - i'd just get another compressor and add it into the system.
By the way, did you know that at one time in the 70's Brook motors' full name was "Hawker Siddeley Vickers Brook Crompton Parkinson.... Motors". What a mouthful! (I still have one of their old catalogues kicking around somewhere)
