Przegląd metod wykrywania ekscentryczności w silniku indukcyjnym z wykorzystaniem analizy prądu stojana

This paper deals with an overview of chosen stator current analysis methods for induction motor eccentricity detection. Field-circuit model of induction motor with static, dynamic and mixed eccentricity has been created in Maxwell 2D environment. Stator phase currents, obtained from the model have been analysed in order to extract symptoms of the faults. In this paper tests results, obtained from the FFT analysis of four diagnostic signals: stator phase current, module of the stator current space vector and positive and negative sequence of stator current, are compared.
