    The only step up VFD's I have ever seen is 120v 1ph in and 240v 3ph out.

    For higher voltage I think you are going to need to use a step up transformer.

    Look at all the sub $2K induction heaters on ebay. Look at the size of the coils. How are you going to shove 60lbs of iron in a coil that size and heat it?

    If you want to make the new motor variable speed so you have more speed control on your lathe you could go with a 3ph motor and a VFD or a DC motor with a DC motor speed controller.

    This is the cabinet I have been looking at. The box is one piece of polymer (plastic) so you don't get all the leaking through the joints. Says it should outlast a metal cabinet.
