Performance optimization in dual stator winding induction machines through flux partitioning

The dual stator winding induction machine can be considered as two different induction machines coupled by the rotor. That will be true if the flux in the air-gap of the machine remains unsaturated. To avoid saturation in the machine two main different strategies can be chosen. This paper will study the performance of both methods. To optimize the operation of the machine the total flux must be partitioned between the two windings. The selection of the flux level in any of the windings will also be studied.
