Abstract
The focus of this paper is to apply time stepping finite element analysis to model large (MW), 11 kV, 3-phase induction motors as a function of the combination of static and dynamic airgap eccentricity. An industrial case history is presented to confirm the validity of the theoretical predictions and actual diagnosis
