摘要

本文提出了一种有效的建模框架来评估双层平面电机的不同新型磁体阵列结构。所提出的工具是半解析的:基于磁荷建模方法解析得到磁通密度,利用麦克斯韦应力张量数值推导电磁力。与有限元法相比,该模型的计算时间最大提高了20倍,并可用于改变磁体阵列的配置,使准哈尔巴赫阵列的二次磁化模式充分利用可用空间。分析了不同的结构,以提高悬浮力和推力,同时减少磁体阵列的弯曲。

Efficient Modeling Framework for the Synthesis of a Novel Magnet Array for Planar Motors
This paper presents an efficient modeling framework to evaluate different novel magnet array architectures for a Dual Layer Planar Motor. The presented tool is semi-analytical: the flux densities are obtained analytically based on the Magnetic Charge Modeling method and the electromagnetic forces are derived numerically utilizing the Maxwell Stress Tensor. The proposed model improves the computation time compared to Finite Element Method with a maximum factor of 20 and is utilized to vary the configuration of the magnet array such that the secondary magnetization patterns of the quasi-Halbach array fully utilize the available space. Different configurations are analyzed in order to enhance the levitation and thrust-forces, while curtailing the magnet array bending.
