The objective of this paper is to improve the torque performance of induction motors by substituting their rotor with a synchronous reluctance rotor, while maintaining the stator’s original configuration. Initially, a finite element method was employed to design and analyze a baseline synchronous reluctance rotor model. In order to optimize performance, a multi-objective genetic algorithm was employed to execute a parametric optimization of the rotor structure. The primary objectives were to maximize the average torque and minimize torque ripple. The rotor's major geometric parameters, such as the dimensions and arrangement of flux barriers, the barrier opening angle, and the distribution of reluctance barriers, were parametrically adjusted during this process. In addition, the researchers examined the impact of rotor material on vibration and torque magnitude. The Pareto front results indicated a region of optimal solutions with comparable performance. The optimal rotor dimensions were subsequently selected and verified from this subset. Simulation results suggest that the average torque increased from 2.19 N·m to 2.71 N·m, while torque ripple decreased from 75.78% in the baseline model to 12.42% in the optimized design. In addition, the overall motor losses were diminished in comparison to the induction motor model by eradicating the rotor cage in the synchronous reluctance configuration. This study concludes that the use of a multi-objective genetic algorithm in conjunction with finite element analysis to optimize the parametrics of a synchronous reluctance rotor is a practical and effective method for enhancing the average torque and minimizing torque ripple.
