Suppression of Rotor-Grounding Bearing Currents Based on Matching Stator and Rotor Grounding Impedances

Suppression of Rotor-Grounding Bearing Currents Based on Matching Stator and Rotor Grounding Impedances

Pulse-width modulation (PWM) inverter drive systems are widely applied in industry for their great speed-control characteristics and performance. However, the common-mode voltage of the inverter induces motor bearing voltage and bearing current, which result in premature bearing failure. In this pap...
