摘要

可变磁阻电机定子的每个齿上都有电枢线圈和磁场线圈。因此,磁场线圈和电枢线圈具有共同的磁通路径。另一方面,电枢线圈是交流MMF源,而场线圈是直流MMF源。电枢绕组具有正弦磁链,而磁场绕组具有直流磁链。本研究探讨电枢和磁场绕组的磁通联系。将磁场绕组分成若干线圈,利用有限元分析方法得到线圈的磁链。通过FFT分析确定了磁链的谐波分量。分析了场线圈连接消除谐波的方法。同样地,研究了电枢绕组的磁链。研究了磁饱和对电枢和磁场绕组磁链的影响。

Analysis of Magnetic Coupling Between Armature and Field Windings of VFRM
There are armature coil and field coil on each tooth of the stator of the variable flux reluctance machine (VFRM). Therefore, field and armature coils have a common flux path. On the other hand, armature coils are AC MMF sources while field coils are DC MMF sources. However, armature windings have sinusoidal flux linkage, but field winding has DC flux linkage. This study investigates flux linkages of armature and field windings. The field winding is separated into coils and flux linkage of a coil is obtained using FEA. Harmonic components of flux linkage are determined by FFT analysis. The elimination of harmonics by the connection of field coils is analyzed. Similarly, flux linkage of armature winding is examined. The effect of the magnetic saturation on flux linkage of armature and field winding is investigated.
