I suppose that those motors won't be charged completely but being overdimensioned will draw rather 4 or 5 than theoretical 6 Amps per phase.
Furthermore "downlifting" will draw less power than "uplifting".

Sounds like some 7 amps for both at a time?

So how many of those motors will run simultaneously? I'd take
50 - 100% security and check in a next step whether this power is easily available at your place. If not you rather should install a sort of "exclusion logic" than to invest in excessive copper graves.
