This paper reports the performance of Synchronous reluctance machine with a conventional rotor structure and a 3-phase auxiliary winding for leading reactive power injection. The machine was built, tested and their measured performance compared to that of a conventional machine of the same dimension and size. It is shown that the modified machine has a saliency ratio clearly influenced by the capacitor. Experimental results of this machine configuration corroborated theoretical analysis and showed that the torque as well as the power factor performance is better compared to conventional reluctance.
