摘要
the present invention is the development of a method for detecting an asynchronous machine desdu00e9fauts emerging from the current acquisition and processing with the egnos. the main feature of this invention is the association of two methods of "average", and "converted to synchronous discrete wavelet u00bbappliquu00e9es in stator.thus, in the context of this invention, we provide the following contributions in the field of monitoring and fault diagnosis of asynchronous machine, the development of a new approach using the cyclo stationarity of signauxu00e9lectriques.determination of the average current with synchronous (tsa), followed by soustractionde the stator current signal, obtaining the current ru00e9siduel. - implementation of the discrete wavelet transform (dwt) discru00e8tewavelettransform - aware in order to diagnose the failure of the induction machine.
