Abstract
A theory has been developed for the performance of three-phase induction motor with star-delta stator winding. Space harmonics of delta and star components of the winding and their space-phase displacements have been taken into account in the analysis. A general computer program has been developed incorporating the new theory for evaluation of performance. Predictions of performance have been verified by tests on a few three-phase squirrel-cage induction motors with star-delta stator connections.
