Surveillance du désalignement d'un moteur asynchrone par analyse du vecteur d'espace courant
Résumé
Recent advances have allowed the widespread use of electromechanical actuators with asynchronous machine in large systems. This article presents a new method of monitoring such actuators by analyzing their current supply. The proposed method is based on a theoretical signature model of mechanical defects in currents, specially developed for this work. The method also takes into account the three-phase nature of electrical quantities. The excellent performances achieved by this approach are illustrated with experimental data.
