Abstract    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 variate papers this approach was used to 3phases SCIMs, but this paper extends the above-mentioned model to 6phases SCIMs. Various simulations of variative faults are carried out on faulty 6phases SCIMs, and then, results obtained the simulation were presented. The innovation in this paper is the first time simulation of broken bars and stator winding faults on 6phases SCIMs using winding function approach with considering magnetic saturation effect that the precise results as well as were presented.

 

Keywords    6Phases squirrel-cage induction motors, saturation effect, rotor fault, stator fault, winding function approach

 

چکیده    مدل مدارهای مزدوج چندگانه (MCCM) موتورهای القایی قفس سنجابی (SCIM) یا روش تابع سیم پیچ، مفصل ترین و کاملترین مدل استفاده شده برای آنالیز عملکرد موتورهای القایی قفس سنجابی می باشد. قبلا از این روش در مقالات مختلف برای موتورهای القایی قفس سنجابی 3 فاز استفاده شده است اما این مقاله مدل فوق را به موتورهای القایی 6 فاز بسط داده است. شبیه سازی های مختلفی از عیوب گوناگون بر روی موتورهای القایی 6 فاز انجام گرفته شده است و سپس نتایج بدست آمده از شبیه سازی ها، ارائه گردیده است. نوآوری این مقاله شبیه سازی برای اولین بار موتورهای القایی قفس سنجابی 6 فاز با روش تابع سیم پیچ با در نظر گرفتن اثر اشباع مغناطیسی با عیوب سیم پیچی استاتور و روتور با میله شکسته شده می باشد که نتایج بصورت دقیق به خوبی نشان داده شده اند.
