SPICE Model of Nonlinear Reluctance for Analysis of a Switched Reluctance Motor

摘要

In a previous paper, the authors proposed a method for calculating the operating characteristics of a switched reluctance motor (SRM) on the basis of the general-purpose circuit simulation program"SPICE." The method was verified by experimental testing of a 4-phase 8/6 SRM. In the analysis, however, we neglected the effects of magnetic saturation. In this paper, we propose a SPICE model of the nonlinear reluctance of the SRM for analysis that takes into account of the magnetic saturation characteristics. The proposed model is verified by comparing the calculated magnetization curves obtained by using the model with those obtained by finite element analysis.
