本文提出了一种用于线性开关磁阻电机（LSRM）的斜齿结构。首先，对作为机器变形和声学噪声主要来源的法向力进行了理论分析。其次，设计了偏斜LSRM，并对偏斜结构的角度进行了分析和优化。然后，使用有限元方法（FEM）计算 LSRM 的法向力输出，并获得该机器的变形结果。推导出法向力与倾斜角的关系。最后，实验结果表明声学噪声有所降低，这证明了所提出结构的有效性。
In this paper, a skewed teeth structure is proposed for the linear switched reluctance motor (LSRM). First, the normal force, as the main source of the machine deformation as well as the acoustic noise, is analyzed theoretically. Second, the skewed LSRM is designed, and the angle of the skewed structure is analyzed and optimized. Then, the normal force output of the LSRM is calculated using the finite element method (FEM), and the deformation results for the proposed machine are obtained. The relationship of the normal force and the skewed angle is derived. Finally, the experimental results demonstrate that the acoustic noise is reduced, which is a testament to the effectiveness of the proposed structure.
