本文提出了一种无刷绕线转子同步电机 (BL-WRSM) 的新拓扑，使用专门设计的定子绕组，通过单个三相逆变器供电。在该拓扑中，由两组匝数不相等的串联绕组组成的特殊定子绕组用于在定子磁动势（MMF）中产生附加的空间分谐波分量。该附加分谐波 MMF (SH-MMF) 组件用于激励 BL-WRSM 的励磁绕组。与现有双逆变器 BL-WRSM 中使用的双逆变器相比，所提出的无刷拓扑的优点是使用单个逆变器。对于转子，有两个独立的绕组：（1）谐波绕组和（2）励磁绕组。谐波绕组和励磁绕组均通过旋转整流器相互并联。附加的 SH-MMF 组件生成旋转气隙磁场，从而在谐波绕组中感应出电压。然后，该感应电压被整流并用于向励磁绕组提供直流电流。通过二维有限元分析来分析和验证这种新型 BL-WRSM 的工作原理。
This paper proposes a new topology for a brushless wound rotor synchronous machine (BL-WRSM) using a specially designed stator winding supplied through a single three-phase inverter. In this topology, a special stator winding, which comprises of two sets of series-connected windings with an unequal number of turns, is used to generate an additional spatial sub-harmonic component in the stator magneto-motive force (MMF). This additional sub-harmonic MMF (SH-MMF) component is utilized for exciting the field winding of the BL-WRSM. The advantage of the proposed brushless topology is the use of a single inverter compared to a dual inverter used in the existing dual inverter BL-WRSM. For the rotor, there are two separate windings: (1) harmonic winding and (2) field winding. Both the harmonic and field windings are connected in parallel with each other through a rotating rectifier. The additional SH-MMF component generates a rotating air-gap magnetic field, which induces the voltage in the harmonic winding. This induced voltage is then rectified and used to supply a dc current to the field winding. A 2-D finite element analysis is performed to analyze and verify the operating principle of this new BL-WRSM.
