Still thinking about a phase convertor...

I've just seen this transformer on eBay which is rated at 10 kVA. It says
the primary is rated at 240 - 480 V and the secondary at 120 - 240 V. Do
you think this might be suitable for a phase convertor if used in reverse?
Perhaps there is some way to reduce the voltage slightly before feeding it
to the idler motor, or perhaps the motors would stand 480 V? We don't get
the full 240 V from our supply anyway.

Here is the link:

The single phase 10 KVA transformer looks like it can be wired to take 240
vac up to 480 vac. Transformers dont mind being reverse connected, as you
probably know, even though the primary is conventially wound closest to the
core. The eBay transformer would be a good choice for your need to use a
480 vac idler to make 480 vac 3 phase from a 240 vac power source..
I asume that you are more comfortable with 480 vac than I am. I hate
480.
