I use a rotary phase converter for my milling machine, and it's 240V only.
The converter itself is basically a 3 phase motor with some wires to a couple of terminal blocks. It works great for the milling machine, which I've wired in delta.
However, I've just acquired two 3 phase pillar drills, which are 380-415v only. The motor info looks like this:
I've taken the terminal cover off, and there's no way to easily wire it up in delta (as in, it's not got enough terminals exposed):
Firstly, I assume that I can't wire this in delta, or might it be possible by some form of black magic?
Secondly, is there a way to up the line voltage from 240V to 400-odd before the rotary converter? I've read somewhere about someone using a yellow brick in reverse, but I cannot find the thread any more, and it was hazy on details anyway.
The motor I'm using in the rotary is a 3hp one, and I only have a 16 amp supply to play with.
