| Popis: | This paper deals with the modeling and diagnosis of the demagnetization fault in the permanents magnets synchronous motors. To do this, a numerical model based on the finite element method under the Flux 2D software has been developed. This model makes it possible to accurately describe the exact geometry of the PMSM and its physical behavior, taking into account all electromagnetic phenomena. In this model, the demagnetization fault has been introduced by creating a partial fissure on the permanent magnet surface periphery. To highlight the interest of the employed model and the efficiency of the line current spectrum analysis technique; a series of simulations are carried out in the two operating modes: healthy operation mode (without demagnetization fault) and faulty operation mode (with demagnetization fault). |
