This research demonstrates improved torque performance in flat-wire motors using a genetic algorithm and the TOPSIS method for rotor design.

The combined optimization approach enhances torque characteristics in flat-wire motors, significantly increasing average torque to 165.32 N·m.
Optimization reduced torque ripple from 28.37% to 13.32% and cogging torque decreased from 896.88 mN·m to 187.9 mN·m.
Global multi-objective optimization was performed through simulations using Maxwell, Workbench, and Optislang, in conjunction with the TOPSIS method.
This research highlights the effectiveness of using rotor slot structures in improving the performance of permanent magnet synchronous motors.
