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

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