提出了一种计算非正弦供电时的高速变频电机铁耗的简单而有效的方法.该方法以谐波分析法为基础,能够综合考虑电源谐波、电视铁芯饱和以及集肤效应的影响,具有较高的精度,与有限元法计算结果的比较表明,该方法具有较高的精度。

A simple and efficient method for the calculation of iron loss in high-speed induction mo- tor fed by nonsinusoidal voltage source is proposed. This method is based on harmonic analysis meth- od, which can take into account the influence of harmonic effect, saturation of magnetic material and skin effect. The computational results of the method and finite element method (FEM) were found to correspond satisfactorily.
