Abstract

This paper presents a reluctance network analysis (RNA) model of a switched reluctance motor considering iron loss. The proposed RNA model consists of a multiple number of nonlinear reluctances and magnetic inductances that express magnetic hysteresis. The validity of the proposed model is proved by comparing calculated values with measured ones. Furthermore, differences between symmetric and asymmetric excitation are investigated
