Performance of any electrical machine during dynamic and steady state condition is assessed by stability analysis of the machine. Three phase induction motors are widely used for a number of applications in industries because of their reliability and low cost. In close loop control system complex circuits are there so the problem of stability is always arises. In this paper a dynamic model of voltage flux linkage relationship. A linearized model is used to evaluate the control characteristics of the five phase induction motor drive which is based on the Conventional methods such as Root Locus technique, Bode plot, Nyquist plot etc. are used for stability analysis of high phase induction machine. Small perturbations are applied with the model to evaluate the control performance. Voltage current relationship is developed to study the behavior of the machine. In this paper voltage-current model is utilized to determine the stability of the motor under different load conditions. MATLAB codes have been developed to carry out this study.
