Résumé

This paper presents a survey of the diagnosis methods detecting the stator faults of the induction machines without modeling. The fault signature is based on the analysis of the negative sequence symmetrical component of the current. Two approaches are described and compared: the spectral analysis of the signature using the Discrete Fourier Transforms (DFT), the Short-time Discrete Fourier Transform (SDFT), the Gortzel algorithm and the synchronous demodulation of the current space vector. The theoretical principles of these methods are presented and their performances compared. The main purpose of this study lies in the investigation of the computational tools dedicated to the diagnosis and minimization of computing time. These methods are applied to an induction machine of 1.1 kW.
