Reluctance Motors sometimes occur hunting phenomena due to machine parameters or drive conditions, therefore high quality speed control is difficult.The hunting tends to occur in small size machines which have large armature resistance, and direct and quadrature axis reactance ratio which is important parameter to determine output of reluctance motors has large effects to stabilize the reluctance motors.Therefore, quantitative analysis upon hunting for machine parameters and drive conditions are very important knowledge to design and control of reluctance motors.In this paper, effects of machine parameters, drive conditions and regions to occur the hunting oscillation are analyzed quantitatively by using Lyapunov Method which is useful for stability analysis of nonlinear systems.
