A three‐dimensional model is necessary for the magnetic field analysis of transverse magnetic flux type linear synchronous motors. However, it is unsuitable for design calculation because of the high calculation costs. In order to virtually represent the magnetic path of a three‐dimensional arm on a two‐dimensional model, we propose the use of virtual arms, which are provided above and below the armature core teeth. In the proposed two‐dimensional model, almost the same thrust waveform is obtained with a calculation time of less than 1/30 compared with the threedimensional analysis. The proposed model is also applicable to transverse magnetic flux and longitudinal magnetic flux hybrid type linear synchronous motors.

横向磁通型线性同步电动机的二维磁场分析模型的建议

横向磁通型线性同步电动机的磁场分析需要一个三维模型。但是，由于计算成本高，因此不适合设计计算。为了在二维模型上虚拟表示三维臂的磁路，我们建议使用虚拟臂，它们位于电枢铁心齿的上方和下方。在提出的二维模型中，与三维分析相比，以不到1/30的计算时间获得了几乎相同的推力波形。该模型还适用于横向磁通和纵向磁通混合型线性同步电动机。
