A Method for Roughly Calculating of Coreless Axial Flux Permanent-Magnent DC Brushless Motor's Air Gap Field Based on MATLAB

从M axwell电磁方程组出发,利用分离变量法分析了APDBM的气隙磁场的分布,推导出气隙磁场的解析表达式,并利用MATLAB强大的计算功能对轴向磁通永磁直流无刷电机的气隙磁场进行了计算并绘制出了气隙磁场分布图,为随APDBM的尺寸及永磁材料的变化而改变的电机参数提供了一种快速计算的有效手段。

This paper sets out from Maxwell electromagnetic equations, analyzes field distribution by employing method of separation variables, and applies MATLAB＇ s powerful ability to calculate the air gap field of permanent-magnet axial-field DC brushless motors and plot the field distribution. It offers an effective method to rapidly calculate the parameters of motor relative to variations in APDBM dimensions and permanent-magnet material.
