Abstract A novel simplified and fast-built flux-linkage analytical model for the switched reluctance generator (SRG) is proposed. By means of the Fourier series in expression of the current-dependent arctangent function, the proposed model can be built with only five flux-linkage data points of several special rotor positions. At the same time the voltage and torque equations of SRG are proposed with the method. Comparing to the conventional methods, which require numerous flux-linkage current-position data, the proposed model is of easy implementation and high comput- ational efficiency. Based on the modeling method, a self-excited SRG model is built and the characteristics of the self-excited SRG are studied. The accuracy of the model is verified via comparison with laboratory measurements of the machine voltage and current waveforms as well as several characteristic curves. The proposed model is shown to have a good accuracy.
