| Abstract: | A harmonic equivalent circuit of BDFM (Brushless Double-Fed Machine) is proposed based on the ana-lysis of the magnetic field distribution of BDFM and the analysis of the harmonic magnetic filed reciprocity among the stator power winding, the stator control winding and the rotor winding. The creation of the harmonic torque and its influence on the operation performance of BDFM are then analyzed. Moreover, the induction voltage in the stator windings resulting from the harmonic magnetic field of the induction current in the rotor winding is analyzed, and the reason for creating the circular current in a parallel branch of stator windings are presented, thus a theoretical foundation for the design and harmonic analysis of BDLM being laid. |
