摘　　要：针对11 kW径向励磁结构无刷直流电动机,采用场路结合法分析了规定的性能指标及主要尺寸下不同极对数的选择及性能,确定两对极方案为最佳方案。其设计过程对于提高无刷直流电动机的设计精度具有一定参考作用。Performance of a 11 kW radial exciting brushless DC motor with different pole pairs was researched under stated performance index and major dimension. The design method combining field and circuit was used in the analysis and finally reached the conclusion that the blue print of two pole pairs was the best. The design process presented in this paper was useful for improving the design precision of brushless DC motor.
