An accurate inter-turn short circuit faults model dedicated to induction motors
International Journal of Electrical and Computer Engineering (IJECE), 2021 Safety, disponibility and continuity of industrial systems are major issue in maintenance. In the last decades, these points are the important axes in the field of research. In fact, in many industrial processes research has picked up a fervent place and a particular importance in the area of fault diagnosis of electrical machines, in fact, a fault ...
