PARK MODEL OF SQUIRREL CAGE INDUCTION MACHINE INCLUDING SPACE HARMONICS EFFECTS

Mohamed Boucherma – Mohamed Yazid Kaikaa –Abdelmalek Khezzar

   An accurate and simpler approach for modelling and simulating the dynamic behavior of squirrel cage induction machines is presented here. The model is based on multiple coupled circuits and takes into account the geometry and winding layout of the machine. All inductances are derived by means of the winding function approach (WFA) and are integrated with the decomposition into their Fourier series. An important issue in such effort is the modelling of the induction motor including rotor slot harmonics (RSH) under symmetrical and asymmetrical conditions, with minimum computational complexity. Simulations results have shown excellent match with theoretically predicted RSH components.
