Abstract

The paper presents the results of research on the spatial distribution of the multi-phase, distributed windings in electric machines. The focus was on the analysis of the harmonics of the current linkage spatial distributions. To perform calculations for different windings patterns, taking into account the number of phases, pole pairs, and the number q of slots per pole and phase, the dedicated code was developed in the Matlab environment. Nine different multi-phase windings were studied, for which magnetomotive force (MMF) was determined to investigate the harmonic content and total harmonic distortion. The obtained results were compared with a reference three-phase symmetric system. Studies were also carried out on torque ripple and power density for different numbers of winding phases.

带有分布式绕组的多相机器的电流联动谐波分析

本文介绍了有关电机多相分布式绕组空间分布的研究成果。重点是分析电流联动空间分布的谐波。为了对不同的绕组模式进行计算，同时考虑到相数、极对数以及每极和每相的槽数 q，在 Matlab 环境中开发了专用代码。研究了九种不同的多相绕组，并确定了其磁动力（MMF），以调查谐波含量和总谐波失真。获得的结果与参考的三相对称系统进行了比较。此外，还对不同相数绕组的扭矩纹波和功率密度进行了研究。
