Abstract

A calculation method, which allows a time efficient coupling of the machine stator and moving rotor parts and force calculation in electrical machines, dedicated to 3D Finite Element (FE) models, is presented in this paper. The method requires only a single mesh generation at the beginning of the simulation. The applied force calculation method is stabilized, using a whole air gap averaging method, which does not require a special air gap mesh. Standard tetrahedral mesh elements can be used in the air gap, without affecting the torque or force calculation results even for the numerically demanding cogging torque calculation.

具有时效性气隙耦合和稳定转矩力计算的电机三维数值计算方法
本文提出了一种用于电机三维有限元模型的计算方法,该方法可以实现电机定子和运动转子部件的时间高效耦合以及电机的力计算。该方法只需要在模拟开始时生成一个网格。施加力计算方法稳定,采用全气隙平均法,不需要特殊的气隙网格。标准的四面体网格单元可以在气隙中使用,即使对于数值要求苛刻的齿槽扭矩计算,也不会影响扭矩或力的计算结果。
