In modern electric equipment, especially electric vehicles, inverter control systems can lead
to complex shaft voltages and bearing currents. Within an electric motor, many parts have
electrical failure problems, and among which bearings are the most sensitive and vulnerable
components. In recent years, electrical failures in bearing have been frequently reported in
electric vehicles, and the electrical failure of bearings has become a key issue that restricts
the lifetime of all-electric motor-based power systems in a broader sense. The purpose of …
