Advantages

Prevention of overvoltages on the motor
Long cable lengths possible
Reduction in motor noise
Minimize of bearing currents
Minimize of in leakage currents (is beneficial in the event of incorrect RCD tripping)
Reduction in line‑borne and field‑borne emitted interference: can be omitted from shielded cables, where necessary
Reduction in motor losses
