VFD 3ph inductor
In some cases I have put them in both, but some VFD manuf, suggest at least between VFD and motor particularly if a non-vector motor is used.
At 50 to 600hz, the inductive reactance is low, but offers a high impedance to the high frequency switching pulses.
There was another link here today showing a 1 phase reactor for the VFD that uses 1ph input.
