A direct field-circuit-motion coupled modeling of switched reluctance motor

A direct field-circuit-motion coupled model combined with finite-element analysis is presented to simulate the steady operating state of switched reluctance motors and to calculate the dynamic currents and torques of the motors. The related control strategies of driving system could be implemented easily using this model, and various phase windings energized operating states could be analyzed accounting for material nonlinearities and the effects of mutual coupling between motor phases. The model is used to study normal operating state and a fault operating state with one branch of a phase winding broken. The comparison and analysis of the numerical and measured results indicates the validity of the model and method proposed in this paper.
