摘要
采用局部坐标法，对任意位置的导线，通过三维空间的坐标变换，推导出了具有矩形截面直线形、圆弧形截流导线产生的三维磁场的计算解析式；并处理了积分过程中的奇点问题。由此可便于精确计算电机绕组、变压器线圈和螺线管线圈等具有上述特征的载流导线所产生的三维磁场。
In the paper,a formula for computing 3-D magnetic field of arbitrarily positioned,straight or circular conductors with rectangular cross section is developed. The formula isbased on the local coordinate method in conjunction with a 3-D coordinate conversion,and atreatment of singular integral is also introducted.This formula allows us to compute accu-rately the 3-D magnetic field of conductors such as motor(generator)winding,transformerwinding,and spiral winding.
