Switched reluctance motor drive systems dynamic performance prediction under internal and external fault conditions

In this second of a set of two companion papers on the dynamic performance of switched reluctance motor drive systems, the results of using an iterative approach to predict the dynamic performance characteristics of a motor drive system during fault conditions are presented. The method is applied to a 6/4, 0.15 hp, 5000 r/min switched reluctance motor drive system to study an external fault due to the failure of a transistor in the converter. The model is also used to study an internal fault due to a partial armature phase short. The analysis resulted in the performance characteristics of the motor drive system which are verified by comparison to experimental data. In addition, the effects of mutual coupling between motor phases on the analysis results are evaluated. >
