Answer / sunil patwal

Yes, One vfd is possible to connect two induction motors at
the same time but VFD selection is depand on motor rating.

Answer / kunal salunkhe

It depends on the power rating of the power semiconductor
components used in VFD. Ideally the logic board which are
DSP based in most cases can be used to trigger two sets of
the power semiconductor converter circuits. but the power
semiconductor devices ratings decide whether you can connect
two motors to it or not.
