本文设计了一款额定功率 48 kW、额定转速 10000 r/min 的车用永磁同步电机（Permanent Magnet Synchronous Motor，PMSM），并通过有限元分析验证了其磁路合理性与效率水平，满足车辆驱动性能要求。

This paper designs a Permanent Magnet Synchronous Motor(PMSM) for electric vehicles with a rated power of 48 kW and a rated speed of 10000 r/min. Its magnetic circuit rationality and efficiency level are validated through finite element analysis, meeting the performance requirements for vehicle driving.
