摘要

This paper investigates the analysis and modeling of an induction motor with ball bearing faults based on coupled-circuit model and modified winding function method (MWFM). The impact of the bearing fault is reflected in the variation of air gap profile, and the inductances terms in the coupled-circuit model are calculated and updated for each time step using MWFM. We show that dynamic simulation ...
