摘要：为了提高传统V型永磁（V-shaped permanent magnet，VPM）磁极性能，设计了一种V型交替极永磁（V-shaped consequent-pole permanent magnet，VCPM）结构。将永磁体与相邻铁心形成一对极磁场，从最大平均扭矩与最小转矩波动幅度层面出发，对变转速永磁电机进行参数优化，实测验证理论分析与有限元仿真的可靠性。研究结果表明：实际测量结果与模拟结果基本一致，说明理论和数值模拟过程是可靠的。该研究有助于提高永磁同步电机的工作效率，为后续的参数优化奠定一定的理论基础。

Abstract: In order to improve the pole performance of the traditional V-shaped permanent magnet (VPM), a V-shaped consequent-pole permanent magnet (VCPM) structure is designed. A pair of pole magnetic fields is formed between the permanent magnet and the adjacent core. Starting from the aspects of maximum average torque and minimum torque fluctuation amplitude, the parameters of the variable-speed permanent magnet motor are optimized. The reliability of the theoretical analysis and finite element simulation is verified through actual measurement. The research results show that the actual measurement results are basically consistent with the simulation results, indicating that the theoretical and numerical simulation processes are reliable. This research is conducive to improving the working efficiency of permanent magnet synchronous motors and lays a certain theoretical foundation for subsequent parameter optimization.

0引言
永磁同步电机因具备能量转换效率高、可实现高转矩、控制精确的多项优势，在汽车运输和航空航天设备等多个行业都发挥着广阔作用[1-2]。相对于常规的表贴型永磁构造，采用内嵌式永磁（IPM）架构可以实现更灵活的系统，实现理想的集磁效应，并实现优异的弱磁扩速性能，可满足高速运转的控制要求[3-4]。针对上述情况，学者们开发获得了不同类型的磁极结构，包括一字结构和多层组合的永磁系统。相对其余内嵌式永磁（IPM）结构，V字形的永磁（VPM）结构更加简单[5]。
近些年，越来越多学者对各种类型电机气隙磁场的调控机制开展了深入研究，相关研究成果取得了重大突破。胡鹏飞等[4]结合气隙磁通密度函数和永磁体磁化方向厚度函数，得到偏心磁极永磁电机径向气隙磁通（未完，下一页）
