摘　　要：针对无刷双馈电机绕组的特殊性,将定子功率绕组分别与转子笼型绕组的磁场耦合,以产生转子电流,分析了定子功率绕组、控制绕组和转子绕组电流产生的谐波磁场,以及定、转子3个绕组电流所产生的各次谐波磁场及各次谐波磁场之间的相互作用,为无刷双馈电机的设计及其谐波分析提供了理论依据.Aiming at the particularity of the windings in BDFM (Brushless Doubly-Fed Machine), the magnetic filed between the stator power winding and the rotor winding, as well as that between the stator control winding and the rotor winding, is coupled, thus producing the rotor winding current. The harmonic magnetic field resulting from the currents of the stator power winding, the stator control winding and the rotor winding of BDFM is also analyzed. Furthermore, the harmonic magnetic filed reciprocity among the above-mentioned currents is discussed. Thus, a theoretical basis for the design and harmonic analysis of BDFM is laid.
