Firstly, SRM inductance function Land flux linkage function ψ are derived from ANSYS which is used for electromagnetic field analysis. Secondly, the non-linear inductance model and non-linear flux model of switched reluctance starter/generator are finished by MATLAB. Based on the latter, the start characteristic of SRM is studied comprehensively. Finally, on the basis of academic research, we completed the starter/generator stand of test and experimented on a sample motor and then experiment waveforms are obtained which verified the simulation model.
