| Abstract: | This paper investigates the different forms of bearing electromagnetism damages. The bearing electromagnetism damage problem induced by Pulse-Width Modulation (PWM) inverter is discussed. The signals of stator to ground voltage and rotor to ground voltage are obtained via experiment. A model of PWM inverter-fed system is established. The simulation results agree with the experiments. |
