Given the numerous possible rotor combinations with different forms of flux barriers, designing an optimal synchronous reluctance motor without the use of mathematical equations and a clear algorithm will be very time-consuming. In this study, a comprehensive method is used to design a synchronous reluctance motor with an external rotor and a flux barrier shape adopted from the behavior of fluids around a solid rotor. According to the new topology, an external rotor synchronous reluctance motor is designed. Multi-objective Taguchi optimization algorithm based on finite element analysis (FEM) is used to maximize the average torque and reduce the torque ripple.This motor is designed for 300 W electric scooters with a six-pole rotor, a 36-slot stator, and a distributed winding. Finally, a prototype of the proposed motor is constructed to validate the results of simulations. The experimental results confirm the accuracy of the design method.}, keywords = {Finite element method,Magnetic Flux Barrier,synchronous reluctance motor,Torque Ripple}, url = {https://www.ije.ir/article_126148.html}, eprint = {https://www.ije.ir/article_126148_7eb0960330eaad110671b0e0ba229233.pdf} }
