摘要

This paper proposes new current control to reduce eddy current loss (ECL) in switched reluctance motors (SRMs). Motor parameters and flux density of SRMs are pre-calculated by magnetostatic analysis. Eddy current causes the change of the flux density. Current profiles for ECL reduction can be derived from the condition under constant flux density. The ECL can be obtained from transient analysis of FEM (TA-FEM). The TA-FEM, however, require too long calculation time, and it is not suitable for simulation with switching action of drive circuit. In this paper, a simple model is applied to ECL analysis on a circuit simulator.
