An accurate inter-turn short circuit faults model dedicated to induction motors

Safety, disponibility and continuity of industrial systems are major issue in maintenance. In the last decades, these points important axes field research. fact, many processes research has picked up a fervent place particular importance area fault diagnosis electrical machines, prognosis become almost indispensable. The need mathematical model three-phase induction machine, suitable for simulation machines behaviour under conditions, received considerable attention. paper presents new practical more precise motors after introducing inter turn short circuits faults. proposed is based on coupled magnetic circuit theory, capable to take into account any asymmetry conditions. To verify exactitude effectiveness model, results machine interturn presented. spite its simplicity, able provide useful indications diagnostic purposes. Experimental study presented at end show that predicts behavior with good accuracy.
