Magnetic Saturation Impacts on Fault Analysis of Squirrel-cage Six Phases Induction Motors Using Winding Function Approach

Multiple coupled circuit modeling (MCCM) of squirrel-cage induction motors (SCIMs), or winding function approach is the most detailed and complete analytical model used to analyze the performance of faulty SCIMs. Already, in various papers this approach has been used for 3-phases SCIMs, but this paper extends the above-mentioned model to 6-phases SCIMs. Various simulations of variative faults were carried out on faulty 6-phases SCIMs, and then, results obtained fromthe simulation were presented. The innovation of this paper is the first time simulation of broken bars and stator winding faults on 6-phases SCIMs using winding function approach with considering magnetic saturation effect that precise results were obtained as presented.
