摘要

在基波频率比较高的多极大功率永磁同步牵引电机中，电机内部磁场各次谐波的频率也相应提高，谐波磁场会在绕组中感应出涡流，产生高频涡流损耗，使得绕组中附加铜耗大幅增加，不应在设计过程中忽略不计。绕组交流损耗是直流损耗与涡流损耗之和的总称。文章分析了高频大功率永磁同步牵引电机成型绕组中交流损耗的来源、计算方法和影响因素。结合一款8极675 kW高频永磁同步牵引电机建立有限元分析模型，分析定子槽口深度、绕组并绕根数、转子旋转磁场、输入电流时间谐波对绕组交流损耗的影响。计算结果表明，谐波磁场对绕组槽口附近导体电流密度分布影响最大；优化定子槽口深度和绕组并绕根数可以有效降低绕组的涡流损耗，使得绕组交流损耗最小，可以提高永磁同步牵引电机效率。

Abstract

In a multiple-pole and high-power PMSTM with high fundamental frequency

the harmonic frequency of the internal magnetic field increases accordingly. The harmonic magnetic field will induce eddy current in the winding

resulting in high-frequency eddy current loss

which will cause additional copper loss to be greatly increased

and should not be ignored in the design process. AC winding loss is the sum of DC winding loss and eddy current loss. The sources

calculation methods and influencing factors of AC winding loss of PMSTM with high frequency and power were studied. A detailed FEA model of an 8-pole 675 kW high-frequency PMSTM was established. The influence of stator slot opening depth

winding conductor parallel number

rotor rotating magnetic field and time harmonic of input current on AC winding loss were analyzed. The calculation results show that the harmonic magnetic field has the greatest influence on the conductor current density distribution near the slot opening; Optimizing the slot opening depth and winding conductor parallel number can effectively reduce the eddy current loss of the winding

minimize AC winding loss

and improve the efficiency of PMSTM.
