根据“均匀磁化”原理,利用谐波分析方法,对永磁多体直线阵列系统的二维场形进行了计算,得到了精确的解析表达式。运用这些关系式可以计算出二维场的主波及其各次寄生谐波。
According to the theory of “uniform magnetization”, the two-dimensional field shape of the permanent magnet multi-body linear array system is calculated by using the harmonic analysis method, and an accurate analytical expression is obtained. Using these relationships we can calculate the dominant wave and its parasitic harmonics in the two-dimensional field.
