Abstract

In the present paper, a parametric electromagnetic model is developed for the switched reluctance generator (SRG) with the finite element method (FEM) using the ANSYS finite element (FE) package which can be considered appropriately for accurate analysis and optimal design of the SRG. The performance principles of the SRG are briefly explained and some important electromagnetic characteristics of the SRG including phase current and instantaneous input power are predicted using the developed electromagnetic model. Carrying out the transient analysis, there is this possibility to predict the flux waveforms within the machine and therefore a core loss model is then introduced for the SRG. Applying the developed electromagnetic model to an 8/6 SRG, simulation results are presented and some critical issues are identified which can be attended in design of the control system of the SRGs.
