Skew is taken into account in single- and multi-slice 2-D finite-element machine models by skew interface conditions applied at a cylinder hull in the center of the air gap. A set of biorthogonal basis functions is constructed to discretize the tangential magnetic field strength at the interface and to weakly enforce the tangential continuity of the magnetic vector potential. The harmonic filtering as a result of skew is already observed in a single-slice model. Multi-slice models with different numbers of stator and rotor slices increase the modeling accuracy.

通过单层和多层二维机器模型建模偏斜

在单层和多层二维有限元机器模型中，通过在气隙中心的缸体上应用的偏斜界面条件考虑了偏斜。构造了一组双正交基函数，以离散界面处的切向磁场强度，并弱化了磁矢量势的切向连续性。在单切片模型中已经观察到由于偏斜导致的谐波滤波。具有不同数量的定子和转子片的多层模型可以提高建模精度。
