Optimization of magnets in a buried magnet synchronous motor

Abstract

This work focuses on the modeling and optimization of an Interior Permanent Magnet Synchronous Motor (IPMSM), a critical component in modern electrical engineering applications such as electric vehicles and industrial drives. Using Flux 2D and HyperStudy, the motor was simulated and optimized to reduce torque ripple and losses while maintaining the average torque. The optimized design demonstrates improved efficiency, smoother electromagnetic behavior, and better energy conversion. This study highlights the essential role of simulation and optimization tools in advancing the performance and reliability of electrical machines—one of the key areas of electrical engineering. Moreover, one of the main objectives was to reduce the magnet area, and this goal was successfully achieved through the optimization process.
