本文提出了一种先进的自励同步电机设计，具有高转矩能力已经在零和较低的操作速度。定子绕组由一种新型的多相分数槽集中绕组（FSCW）组成，该绕组能够产生各种磁动势（MMF）波，并能够独立控制其振幅和频率。转子包括两个绕组组和连接在它们之间的多相二极管整流器。在零和较低的操作速度下，转子励磁通过谐波电流执行，而对于较高的速度使用MMF绕组谐波。因此，所提出的机器可以在整个速度范围内以高转矩能力运行。新机床的功能已被证明与不同的负载条件下的有限元。
This paper presents an advanced self-excited synchronous machine design with high torque capability already at zero and lower operation speed. The stator winding is composed of a novel multiphase fractional slot concentrated winding (FSCW) which has the ability to generate various magneto motive force (MMF) waves and to control their amplitudes and frequencies independently. While, the rotor contains two winding sets, and a multiphase diode rectifier connected between them. At zero and lower operation speed, the rotor excitation is performed via harmonic currents, while for higher speeds using MMF winding harmonics. As results, the proposed machine can operate with high torque capability over the complete speed range. The functionality of the new machine has been proved with finite elements for different load conditions.
