For information the construction of
the motor insulation, consult the motor manufacturer.Options
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.
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.
