   Any three phase source can supply modest amounts of single phase.
   It would be ehlpful for (or other commentators...) to know more about the
   existing supply:
    Delta?
    Wye?
    Neutral available?
    Manual spec, if any, for unbalanced loads?
    Is there any 'sprare' KVA available?
    Will the single and three phase be used at the same time?

   Ferinstance:
    If delta wired, I'd get a transformer, of appropriate KVA
    for load, arrange breakers to connect it 'line to line' to the
    460 v Alternator.

   Grounding, especially with Tesla Gear may take some thought.

   Sure, could build an inverter, but the above seems simpler.
