Electric vehicles offer an unmatched experience thanks to their torque profiles. They must be optimized when considering intracity driving cycles (frequent start-stop) by dealing sensitively with the efficiency/performance relationship. Asynchronous motors are commonly used in electric vehicles. Parameters like stator/rotor geometry, number of slots, and materials used are incredibly important in the efficiency/performance relationship. This study has focused on the effect of the change in the number of stator/rotor slots on motor performance by designing an asynchronous motor to be used in primarily urban-use electric vehicles. Afterward, the effect of copper or aluminum cage materials on motor performance was obtained with single- and double-layered squirrel cage structures. The first designed motor has an initial torque value of 96.26 Nm while the optimized motor has a value of 115.34 Nm with its efficiency value and thermal limits being developed by 19.82% without changing. According to the analysis results, the squirrel-cage asynchronous motor with a double-layer, 34/46 structure, and aluminum material exhibited the best performance with initial torque.
