Abstract

This paper presents the use of magnetically-coupled, double three-phase windings to improve the performance characteristics of synchronous reluctance machine with a simple salient rotor. This machine with both three windings housed in the same stator structure has the main winding connected to the main supply and the auxiliary connected to balanced capacitance for leading current injection. The power factor and torque performance characteristics of the machine with the scheme were investigated using the electromagnetic field and coupled circuit concepts and it is shown to have a desirable characteristics. The influence of the capacitor in energy conversion were also examined, the nature of the airgap flux distribution were determined and net flux of the machine with the scheme is shown to be sinusoidal.
