    DIAGNOSTIC DES DEFAUTS ET ANALYSE ELECTROMAGNETIQUE EN 2D DES MACHINES ASYNCHRONES

    In this study, the broken bar current is given a non-zero value, and the broken bar is modelled by a large resistance. The FEM machine fault model is used to study the behaviour of the machine under various fault conditions, such as fault (broken bar). We have shown the evolution of the local quantities (the lines of the magnetic field, the magnetic induction), as well as the global quantities (the currents, the electromagnetic torque, and the speed). The analysis provided by the finite element approach then demonstrates that it is a useful and affordable way to analyze the impact of rotor defects on the behavior of asynchronous machines, and has enabled us to comprehend and quantify the local effects of rotor faults. These outcomes provided compelling evidence for the efficiency of the approach employed in our investigation in identifying flaws (broken bars) in the squirrel cage rotor and anticipating future issues with the device. A validation of the accuracy of our work from the third chapter, where we utilized the MATLAB software, is also expressed in this chapter utilizing the Flux2D® SOLVER tool
