摘要

本文通过研究轴向磁通永磁电机的体积元对空载磁通机构的贡献,对轴向磁通永磁电机有效极弧系数的确定进行了全面的研究。所提出的方法包括使用数学表达式对磁通链进行评估,该表达式对pm体积上的函数进行积分,而不是传统的线圈表面上的磁通密度积分。利用二维有限元(FE)对该过程进行了分析,结果表明,使磁链与PM体积之比最大化的极弧系数在0.5 ~ 0.6之间。

Efficient pole-arc coefficients for maximum no load flux linkage in axial flux permanent magnet machines
This paper presents a comprehensive study towards the determination of efficient pole-arc coefficients for axial flux permanent magnet (PM) machines, through investigation of the contribution of volume elements of PMs to the no load flux linkage. The proposed methodology involves the evaluation of flux linkage using a mathematical expression which integrates a function over the volume of PMs instead of the classical integration of the magnetic flux density over the coil surface. The process is implemented using 2D finite element (FE) analysis, and the results shows the pole-arc coefficients that maximize the ratio of the flux linkage over the PM volume is between 0.5 and 0.6.
