Abstract

In high speed electrical machines, one of the main challenges that can be faced is the high frequency conduction losses in the machine windings due to both skin and proximity effects. This paper studies the effect of using different types of magnet wires on the AC losses of the electric machine windings. Using finite element modelling (FEM), the conductors are subdivided into multiple strands to calculate the losses in each conductor and in each layer. Further, aiming at loss minimization, different arrangements are introduced and compared at a wide range of frequencies. Moreover, recommendations are provided based on the obtained results and comparison.

使用不同类型的磁铁导线对电机绕组交流损耗的影响
在高速电机中,可能面临的主要挑战之一是由于趋肤效应和接近效应导致的机器绕组高频传导损耗。本文研究了使用不同类型的磁铁导线对电机绕组交流损耗的影响。利用有限元模型(FEM),将导体细分为多股,以计算每个导体和每层的损耗。此外,为了使损耗最小化,在较宽的频率范围内介绍并比较了不同的排列方式。并根据所得结果和对比提出了建议。
