Performance prediction of an asymmetrically wound multi-phase (6-phase) induction motor under various phase loss conditions on the basis of comparative analysis is presented. The captured scopes are accompanied by a magnified (zoom) in order to obtain a better sense of the consequences on the torque-ripple content in the resulting time-domain torque profile. The phase loss scenarios analyzed in this paper are based on the simulated result of an AWSP-IM a modeled using MATLAB/SIMULINK platform. The analysis of ripple contents in the torque profiles under various phase loss conditions reflects the deterioration of the torque-profile quality in each case. Further its comparison with result of three phase counterpart shows that AWSP-IM exhibits better performance than the Three Phase Induction Motor (TPIM) under the phase loss without any external control techniques. Moreover, some of the cases gave results, which were very close to the healthy operation of TPIM.
