Abstract

In this manuscript, a novel permanent magnet assisted brushless wound rotor synchronous machine (PMa-BLWRSM) has been presented. Contrary to the existing configurations requiring two inverters for BLWRSMs, the proposed brushless topology requires a single 3-phase inverter. Two dominant components of magneto motive force (MMF) are available in the stator MMF (sMMF) of the suggested PMa-BLWRSM: subharmonic component (SHC) and fundamental component (FC). The SHC of sMMF is utilized to obtain the brushless working of the proposed machine. The rotor design includes two windings: 1) harmonic winding (HW), and 2) field winding (FW). A rotating bridge rectifier is embedded between these two windings. The SHC of the sMMF produces an AC voltage in the HW of the rotor. The produced voltage in HW is given to the rotating rectifier, which converts it into DC. This DC is given to the FW of the rotor. A 2-dimensional finite element analysis is performed using JMAG designer to verify the operating principle of the suggested 8-pole and 12-slot PMa-BLWRSM. In comparison to existing BLWRSM, the proposed machine provides high starting and average torques with less input stator winding current and low torque ripples. The proposed machine can be used for applications requiring high starting torque.

一种改进转矩特性的新型永磁辅助无刷绕线转子同步电机

本文介绍了一种新型永磁辅助无刷绕线转子同步电机（PMa-BLWRSM）。与blwrsm需要两个逆变器的现有配置相反，提出的无刷拓扑需要一个单一的三相逆变器。所建议的永磁- blwrsm定子磁动势（sMMF）中有两个主要的磁动势分量：次谐波分量（SHC）和基波分量（FC）。利用sMMF的SHC来实现该电机的无刷工作。转子设计包括两种绕组：1)谐波绕组（HW）和2)磁场绕组（FW）。在这两个绕组之间嵌入一个旋转桥式整流器。sMMF的SHC在转子的HW中产生交流电压。以HW为单位产生的电压给旋转整流器，由整流器将其转换成直流电。这个直流电被给予转子的FW。利用JMAG设计软件进行了二维有限元分析，验证了所提出的8极12槽PMa-BLWRSM的工作原理。与现有的BLWRSM相比，该电机具有较高的启动和平均转矩，且输入定子绕组电流较小，转矩波动较小。所提出的机器可用于需要高启动扭矩的应用。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
