Dynamic performance analysis of reluctance motors using damping and synchronising torques

The authors analyse the dynamic performance of polyphase reluctance motors using damping and synchronising torques. A numerical algorithm has been applied to obtain these torque components in the time domain using detailed nonlinear models of reluctance motors. The effects of all electrical motor parameters have been examined and the optimum values of parameters, which give maximum damping of hunting oscillations, have been obtained. It has also been demonstrated that these optimum parameters substantially improve the dynamic performance of reluctance motors. The presented results form a guide to the production of reluctance motors with well-damped oscillations and improved dynamic performance
