The need for du/dt filtering depends the motor age
and insulation.e. however separate mains choke
are needed they are available eet different system
design needs.
Insulated N-end (non-driven end) bearings and/or
common mode filters are also required for motor bearing
currents with motors bigger than 100 kW.4

du/dt filters
du/dt filtering suppresses inverter output voltage spikes
and rapid voltage changes that stress motor insulation.
Mains chokes
Mains chokes are typically used reduce harmonics
in the mains current. If
the motor does not fulfil the requirements the filter
