Comprehensive Eccentricity Fault Diagnosis in Induction Motors Using Finite Element Method Academic Article uri icon


  • Load variation along with static and dynamic eccentricities degrees is one of the major factors directly affecting the dynamic behaviors of eccentricity signatures as observed in the current spectrum of induction motors. Without taking the effect of load variation into consideration precisely, the change in the static and dynamic related fault signature amplitudes provides misleading information where the eccentricity degree and the load level exhibit similar effects in the current spectrum. In this paper, we address all these factors in a unified framework by analyzing various combinations both theoretically and experimentally. For this purpose, the time-stepping finite element method (TSFEM)-based, load-level-independent method is proposed to determine the static and dynamic eccentricities degrees individually. 2006 IEEE.
