Abstract :The transient and dynamic performance analysis of a proposed line-start, three-phase concentrated dual-winding synchronous reluctance motor insert ignore into journalissuearticles values(cDWSynRM); in comparison with the conventional concentrated winding synchronous reluctance motor insert ignore into journalissuearticles values(cSynRM); was presented. Both windings are overlapping windings. The cDWSynRM consist of main and auxiliary windings with capacitive assistance for power factor improvement. The modelling of the synchronous reluctance motors insert ignore into journalissuearticles values(SynRM); was done in direct-phase variables considering only the fundamental magneto-motive force insert ignore into journalissuearticles values(MMF);. The machine inductances of both machine models were determined using winding function theory insert ignore into journalissuearticles values(WFT);. These derived inductances were used to determine machine performance characteristics such as Torque, Speed, Phase currents etc. The performance characteristics of both motors were monitored using MATLAB/Simulink, and the proposed line-start cDWSynRM with capacitive assistance was observed to have improved performance characteristics when compared to the cSynRM.
