Default Can a 3 phase motor be somehow used as a generator?

No, it will burn out. That's DC injection braking, what most VFDs
use for the final stage of stopping a motor. It may be necessary
to blip some DC on an induction alternator to get it excited,
but apparently with a cap back across the windings, they usually
will self-excite as long as there's no load on it.
