Abstract

Permanent Magnet Synchronous Motors (PMSMs) are extensively employed in various applications, including electric vehicles, industrial machinery, and precision motion control systems, owing to their high efficiency, power density, and excellent controllability. The performance of these motors is strongly influenced by several design parameters, notably the slots-per-pole-per-phase ratio, stator winding configuration, permanent magnet arrangement, and slot opening width. This study investigates the impact of each of these parameters on key motor performance metrics, such as output torque and torque ripple. In this study, the effects of each parameter on output torque and torque ripple are examined individually and in combination. Simulation results demonstrate that appropriate optimization of these factors can significantly enhance the motor's electromagnetic performance. Based on these findings, an improved motor structure is proposed, and its performance is compared to that of the initial design.
