| Abstract: | The classical circulating bearing current is first reviewed to help understand how a flux lin-(kage) can induce bearing currents.Thecirculating bearing current generated by a high frequency flux in the inverter driving motor is discussed.This paper makes a theoretical analysis of the generation mechanisms of circulating bearing current;and describes the experimental findings,and states why the circulating bearingcurrent should be related to a flux linkage produced by the common mode(coupling) current,and explains the relationship between the common mode coupling current and the circulating bearing current in inductionmotors. |
