摘要

本文研究了一种计算表面贴装式永磁同步电机齿槽转矩和气隙磁通密度的方法。首先，建立了SPMSM的简化模型并对其进行了电磁分析，在二维极坐标系下，基于Maxwell方程推导了SPMSM的磁矢量势。利用适当的边界条件推导出气隙磁通密度，并根据解析解计算出齿槽转矩。通过所提出的方法得到了分析结果，并推导出满足spmsm最佳齿槽转矩的转子斜度、斜角和分段。通过与有限元法分析结果的比较，验证了所提方法的准确性。

Analytical Study and Experimental Verification of Electromagnetic Vibration Sources and Optimization of Rotor Skew in Surface-Mounted Permanent Magnet Synchronous Machines

In this article, a method for calculating the cogging torque and air-gap flux density of a surface-mounted permanent magnet synchronous machine (SPMSM) is studied. First, a simplified model of the SPMSM is presented for electromagnetic analysis, and the magnetic vector potential is derived using the governing equations based on Maxwell’s equations in a 2-D polar coordinate system. The air-gap flux density is derived using appropriate boundary conditions, and based on analytical solutions, the cogging torque was calculated. The analysis results derived through the proposed method, and the skew of the rotor, the skew angle, and segment that satisfy the optimal cogging torque of SPMSMs are derived. The accuracy of the proposed method is verified through a comparison with the analysis results with the finite element method (FEM).
