摘　　要：横向磁场电机具有电磁解耦、设计灵活、输出力密度大等优点,引起广泛关注。但是该种电机磁路复杂,需采用三维场分析。在三维有限元磁场中如果对电流区域进行适当处理,采用标量磁位进行分析,可以比采用矢量磁位大大提高计算速度。本文首先对任意形状的电流区域在不同坐标系下的一般处理方法进行了系统推导;然后,将该一般方法进一步应用于特殊情况下的电流区域,使得问题得到简化;最后,根据所推导的原理编制三维有限元软件,利用该软件对样机磁场进行计算,试验结果表明了该方法的正确性。Transverse flux machine（TFM） has many advantages such as electromagnetic decoupling, design flexibility, high force density and so on. But its flux paths are very complex and must be analyzed with 3D method. If using the scalar potential instead of the vector potential to analyze the current-carrying regions in a 3D magnetostatic field, the computing time can be greatly reduced. Firstly, the general processing method of the arbitrarily-formed current-carrying regions in different coordinate systems is put forward in this paper. Then this method is applied in the analysis of several special current-carrying regions, which simplifies the computation. In the end, a S3DFEM program is developed based on the method. And the magnetostatic field of a prototype transverse flux machine is analyzed by this program. The acquired results prove that the suggested method is correct and reliable.
