Single phase output VFD. Expensive, yes.
I suspect it is a 2 phase 90deg phase angle, like the old 2 phase here in Buffalo. Probably has seperate connections to the start and run windings.
Not real practical, but I was surprised that they do exist, at least commercialy.

Cheaper, and better, to buy a three-phase motor and matching drive.
Not 2 phase, that is something completely different. The output is single phase, but not very practical for machine tools. See my brief explanation in this thread; http://www.practicalmachinist.com/ub...ic/3/2247.html
