随着工作基频的增加，交流绕组效应正成为交流电机中损耗的主要来源。为了减轻AC损耗，由多股平行导体形成的绕组是常见的，然而这种利兹型构造可能遭受难以建模的循环束损耗。本文提出了一种低成本、可配置的实验方法，用于表征任意几何形状和结构的绕组的交流损耗特性。测试台允许在代表性的工作电流和激励频率下比较不同绕组设计的交流损耗幅度。针对矩形截面导体的尺寸和电导率范围内的二维有限元分析的实验测量进行了验证。此外，测试设置被证明是有效的，在确定多股导线的束级损失。
With increasing operating fundamental frequencies, AC winding effects are becoming a dominant source of loss in AC machines. To mitigate for AC loss, windings formed from multi-stranded parallel conductors are commonplace, however such Litz type formations can suffer from circulating bundle losses which are difficult to model. A low cost, configurable, experimental method of characterising the AC loss behaviour of windings with arbitrary geometry and constructions is presented here. The test bench allows comparison of AC loss magnitudes for different winding designs at representative operating currents and excitation frequencies. The experimental measurements are validated against 2D FEA for rectangular section conductors over a range of size and conductivity. Further, the test setup is shown to be effective in identifying bundle level losses in multistranded conductors.
