Abstract

Multiphase windings or other special windings (fractional-slot, tooth-concentrated, multilayer) have been gained a great interest over the last years due to some advantages that this type of windings provides for alternative current (a.c.) electrical machines. This paper aims to help the machine designer to select the proper winding configurations and to sort out the best winding layout. The classical method based on star of slots and Fourier-series expansion of the air-gap MMF wave was implemented on the computer to quickly determine the values of the main winding factor, space harmonic content and differential leakage coefficient in order to identify the optimal winding structure. Thus, the proposed application becomes a helpful tool in the design process and can be applied for any type of single or multiphase winding layout irrespective of number of layer or number of conductor per slot. The paper also describes how to use this new and original application that is free available on the website www.sarlota. de/RunFastMMF56.html.

多相电机中毫米波谐波含量的快速预测

多相绕组或其他特殊绕组(分槽、齿集中、多层)由于这种类型的绕组为交流电机提供了一些优点，在过去几年中获得了极大的兴趣。本文旨在帮助机器设计人员选择合适的绕线结构，并整理出最佳的绕线布局。在计算机上实现了基于槽星和气隙MMF波傅里叶级数展开的经典方法，快速确定了主绕组因子、空间谐波含量和微分泄漏系数的取值，从而确定了最优绕组结构。因此，所提出的应用程序在设计过程中成为一个有用的工具，可以应用于任何类型的单相或多相绕组布局，而不考虑层数或每个插槽的导体数量。本文还介绍了如何使用这个新的原创应用程序，该应用程序可在网站www.sarlota上免费获得。德/ RunFastMMF56.html。
