| 摘 要： | 提出了一种新型的双边不对称梯形永磁空心直线电动机。首先使用等效磁荷法建立了梯形单块磁体的三维空间磁场解析模型,再由叠加原理得到双边Halbach阵列空心电机的气隙磁密三维模型。在考虑线圈横向端部效应的基础上,推导出电机运行过程中的反电动势与电磁推力的表达式。利用解析模型分析了梯形磁体阵列气隙磁密谐波分布的规律,并对其进行优化;三维有限元仿真结果表明所提解析模型具有较高的准确度,同时采用经过优化的梯形阵列定子,可以达到提高气隙磁密正弦性从而减小推力波动的目的。

| Abstract: | A novel topology of aircore permanent magnet linear synchronous motor (PMLSM) which has an asymmetrical doubleside trapezoidal permanent magnet (PM) stator was proposed in this paper. Firstly, a 3D magnetic field analytical model of one trapezoidal PM was established based on the theory of magnetic charge, and a 3D model of the flux distribution in the airgap of a doubleside PMLSM could be obtained by the superposition principle. Expressions of the back electromotive force and the electromagnetic force are derived with considering the transverse end effect of the coil. The analytical model was used for evaluating and optimizing the distribution of airgap flux density harmonics. Subsequently, the proposed model was verified by a 3D finite element analytical model to demonstrate its accuracy. |
