Bearing Damage Analysis by Calculation of Capacitive Coupling between Inner and OuterRaces of a Ball Bearing
Bearing damage in modern inverter-fed AC drive systems is more common than in motors working with 50 or 60 Hz power supply. Fast switching transients and common mode voltage generated by a PWM inverter cause unwanted shaft voltage and resultant bearing currents. Parasitic capacitive coupling creates...
