Abstract: Aiming at the problem of highly saturated and nonlinear characteristics of the flux linkage, it is difficult to model and analyze switched reluctance motor(SRM) using traditional methods, the issues that how to acquiring SRM′s flux linkage characteristics simply and effectively were studied. An experimental measurement method was proposed in this paper. The principles, circuits, and steps of the experiment were described in detail to build an experimental platform. A fourphase 8/6 pole SRM was measured to obtain the characteristics of flux linkage, and the acquried flux model was compared with the analytical model. The results indicate that the proposed method is simple, convenient and low cost, which can accurately obtain the flux linkage model of SRM. The proposed method is of great significance for simulation and control research of SRM.

Key words: switched reluctance motor(SRM); modeling; flux linkage characteristics
