摘要

针对高速永磁储能电机在计及整流负载时绕组损耗过高的问题,以8极48槽高速永磁储能电机为研究对象,构建绕组损耗数学计算模型,开展绕组损耗层数与并联支路数、换位绕组技术等研究。结果显示：增加电机绕组层数与并联支路数量,能够减少涡流损耗在总损耗中的比例与降低绕组损耗;对绕组槽内换位方式与端部扭转换位方法进行对比分析,证实端部扭转换位方法对绕组交流损耗抑制的有效性。针对电机常用工况,对不同方案的电机性能和效率进行对比,仿真结果表明,所提出的优化方法可降低绕组损耗并提高计及整流负载的高速永磁储能电机的效率,并通过试验验证仿真分析的准确性。

Abstract

Aiming at the problem of excessive winding loss in high-speed permanent magnet energy storage electric machine when rectifier loads are taken into account, an 8-pole 48-slot high-speed permanent magnet energy storage electric machine was taken as the research object. A mathematical calculation model of winding loss was constructed, and researches on the number of winding layers, parallel branches and transposed winding technology were carried out. The results show that increasing the number of winding layers and parallel branches of the electric machine can reduce the proportion of eddy current loss in the total loss and decrease the winding loss. By comparing and analyzing the in-slot transposition mode and the end twist transposition method of the winding, the effectiveness of the end twist transposition method in suppressing the AC loss of the winding was verified. For the common operating conditions of the electric machine, the electric machine performance and efficiency of different schemes were compared. The simulation results show that the proposed optimization method can reduce the winding loss and improve the efficiency of the high-speed permanent magnet energy storage electric machine considering the rectifier load, and the accuracy of the simulation analysis has been verified by experiments.
