Abstract：Aiming at further decreasing the harmonic content of the PM wind turbine，reducing the loss and improving its performance，six-phase double Y 30°-deflected winding of multiphase winding theory was used in the research and development. Ansoft Maxwell 2Dtransient simulation function was used to model ordinary three-phase and six-phase dual Y shift 30° motor，which was the same structurebut only changing stator winding connection. Simulated by the no-load and rated load，and the air gap flux density harmonic of Fourier
was analyzed，etc.. Based on the difference of performance by simulation analysis data，the results indicate that compared with ordinarythree-phase generators，six-phase double Y 30°-deflected generators have advantages such as less higher harmonic content，wider voltagerange，lower loss，higher efficiency，etc..
