本文对高速高功率密度永磁同步电机的交流铜损进行了详细的研究。对于平行股线绕组，由于槽内导体的随机分布，采用有限元模型（FEM）难以准确估算交流铜损。因此，这项工作的重点是从总的测量损耗的交流铜损分量的分离。为了获得更精确的结果，还考虑了制造工艺对定子铁芯的影响。一个三维有限元已被用来评估总的功率损耗，包括端部绕组的影响。最后，考虑到温度对交流损耗的影响，通过监测绕组温度在实验过程中。
This paper presents a detailed investigation of AC copper losses in high-speed high-power density permanent magnet synchronous machine. For parallel strands winding, it is not easy to accurately estimate the AC copper losses using finite element model (FEM), due to the random distribution of the conductors inside the slots. Therefore, this work is focused on the separation of the AC copper losses component from the total measured losses. In order to obtain more precise results, the effect of manufacturing process on the stator core has also been considered. A 3D FEM has been used to evaluate the total power losses including the effect of the end-windings. Finally, the influence of the temperature on the AC losses is taken into account by monitoring the winding temperature during the experiments.
