INVESTIGATION OF THE FACTORS AFFECT PHASE INDUCTANCE IN SWITCHED RELUCTANCE MOTORS
Özet
In this study, the factors affecting change of the phase inductance in a switched reluctance motor (SRM) have been investigated. The motor inductance is a function of both excitation current and rotor position and it depends on motor geometry, relative permeability, saturation and fringing and end-turn field. Non-linearity of SRM leads to difficulties for the development of analytical methods for predicting the flux linkages, co-energy change and inductance at all rotor positions these effects in the 6/4 SRM obtained from analytical way and predicted by 3D finite element method (Ansoft RMxprt, Ansoft Maxwell 3D) have been investigated. Results of simulations and analytical solutions have been relatively compared.
