Slip ring (wound rotor) 3 phase motor, what VFD should I use?
However the motor is wound for 380 V and you are only using 220 V, so that will help My guess is that a dv/dt filter is not necessary 4) I got told that I would need a 2,2kW VFD due to that it is a slip ring motor, is this true? You should select the VFD based on the motor nameplate current You may need extra current for high starting.
