Dynamic measurement of magnetic characteristics of switched reluctance motor

Introduction. Switched reluctance motor (SRM) is a type of electric featuring nonlinear magnetic characteristics. The flux linkage or inductance profile SRM usually required for the purpose high control performance, and can be normally obtained through conventional static test by using DC AC method when rotor locked. Problem. However, it not practical to use measurement specific apparatus locking unavailable. Besides, due nonlinearity SRM, saturation effect makes difficult obtain saturated characteristics, fails address this problem. Novelty. In paper, dynamic magnetization curves proposed which allows take place while running with load. Methodology. Based on test, handles problem successfully introducing offset in frequency voltage. Phase different positions currents analyzing simple equivalent circuit. Practical value. Simulation conducted MATLAB/Simulink environment results have verified that effectively characteristics SRM.
