STATIC PERFORMANCE OF A NEW SRD SYSTEM WITH TWO-PHASE EXCITATION

This paper provides an analysis of a switched reluctance motor (SRM) under two-phase excitation. After a brief introduction of the two-phase excitation scheme, the flux linkage model of a SRM under two-phase excitation is developed using FEA. A linearized model is then established based on the detailed flux linkage analysis. The torque-angle characteristics of such a linear model are compared with that derived from the detailed and nonlinear FEA model. Based on the FEA model, an optimized control strategy is proposed to improve the performance of the SRM under two-phase excitation.
