Thermal and fluid flow field calculation and analysis of preparation of semi-direct drive PMWG

With a 1.65MW semi-direct permanent magnet wind generator (PMWG) for electric vehicle, using the finite element method to calculate the fluid flow field and the thermal field, by calculating the results of experimental data analysis, to verify the correctness of the calculation method; At last,the comparisons of the analysis results were proposed with test data to verify the correctness of calculation.Conclusions can be drawn to provide certain references for designing the PMWG.
