Abstract The harmoniccontents of the brushless doubly fed machine (BDFM) rotor winding are high,which results in the large lossesand the low efficiency of themachine and therefore restricts the industrial applications of the BDFM. To solve the problem,the tooth harmonic principle and the sinewinding theory are applied.The multi-pitch-unequal-turn-multilayer rotor windingstructure of the BDFM is proposed. Thisspecial rotor winding structureisanalyzed in detail with the design example.The new rotor structure can improve the conductor utilization ratiosof the rotor winding and reduce the harmonic contents except for the two main pole pairs. The validity of therotor windingconfiguration is verifiedby the finite element model (FEM) simulation and the experimental analysis of theprototype machine. The experimental results of the prototypemachine show that BDFM with the multi-pitch-unequal-turn-multilayer rotorwindingstructure have good performance.

Key words： Brushless doubly fed machine tooth harmonic sine winding finite element model
