The aim of this paper is to introduce a new fault detection technique based on the use of the instantaneous power factor signature analysis as a tool for the diagnostics of mixed airgap eccentricity in operating three-phase squirrel cage induction motors. Firstly, a modelling and simulation study concerning the occurrence of Airgap eccentricity in three-phase induction motors is presented. For that...
