摘要
将不规则直流线圈等效为若干段载流直导线的组合,通过坐标变换和磁场变换计算出单根载流直导线的磁场,进而叠加求和得到整个不规则直流线圈的磁场。计算示例表明,该方法计算不规则直流线圈的磁场简单易行,可用于实际工程中线圈磁场的计算。
The irregular DC coils can be regarded as the sum of many line current coils.The magnetic field of single current coil can be calculated by coordinate transformation and magnetic field transformation,and then the whole field of the irregular DC coils can be gotten by summing the magnetic fields of current coils.The calculation example shows that the method is very simple for calculating the magnetic field of irregular DC coils and can be used for calculating the magnetic field of coils in practical engineering.
