Abstract :
A novel method to model electrical machines based on winding function theory (WFM) is proposed. In conventional WFM, it is assumed that flux lines in air gap are in radial direction. The main drawback of this assumption is inaccuracy of the simulation results. To improve the accuracy of the WFM, modified winding function theory (MWFM) is proposed. In this method WFM is improved by finite element method (FEM) in which the exact permeance function is calculated by FEM. This new approach possesses a good accuracy beside of low calculation processing time. The simulation results for a 4:6 switched reluctance motor (SRM) based on WFM and MWFM is obtained and are compared with each other. Finally proposed MWFM has been validated by FEM results. These results have shown a good accordance with FEM and therefore MWFM method is practical in such applications which require high speed modeling calculations without losing proper accuracy.
