This thesis investigates a design development and performance improvement of Synchronous reluctance motor with the line-start capability comparable with an induction motor. A three-phase induction motor with the rated output power of 20kW is selected as a benchmark. The aim is to introduce the synchronous reluctance motor designs with the same starting capability of the induction motor under the study. The proposed synchronous reluctance motors have the same stator design as the induction motor but the differences are in the rotor. Since the synchronous reluctance motors are not self-starting. The proposed rotor designs are equipped with the cages and successfully their performances are improved. In the proposed models, two different hyperbolic-line and hyperbolic curve shape of flux barriers are introduced. The performances of these models are further improved by adding the permanent magnets to the rotor flux barriers. All the proposed motor designs are simulated and tested under different loading conditions in FEM software. The performance of the designed motors is satisfactory in both steady-state and starting conditions. The proposed motor designs outperform the induction motor in terms of power factor and efficiency with up to 10% of increment. The outcome of this research is expected for the future investigation of the new configurations of the line-start motors with higher efficiency and power factor.
