摘要
本文借助磁荷与电荷的类比,用磁荷镜象法导出了一种永磁电机中由永磁磁极产生的气隙磁场分布的二维解析解,为设计时合理选择磁极的工作点及外型尺寸提供了方便和依据。
Based on an analogy between magnetic charge and electric charge,a 2-D analytical solution for determining the field distribution produced by permanent-magnet poles in a machine is obtained by the method of images for magnetic charge.The given formulas are suitable for designers in chosing the proper operating point and size of the poles.
