摘　　要：介绍了无刷直流电机(BLDC)分数槽绕组的极槽配合原则,分析了极槽配合对外转子无刷直流电机绕组连接方式、绕组系数、气隙磁场、计算极弧系数、齿槽转矩、定子磁动势谐波、定子铁损耗等影响,并通过Ansoft和Matlab软件对12槽8极、12槽10极、12槽14极和12槽16极四种极槽配合电机进行仿真,验证了理论分析的结果,为电机设计提供了理论依据。Introduction was made to the pole-slot matching principle of brushless direct current motor （BLDC） fractional slot winding. This paper analyzed the effects on winding connection mode, winding coefficient, air-gap magnetic field, pole-arc coefficient, cogging torque, stator magnetomotive force harmonic and the stator iron loss of BLDC. Ansoft and Matlab were used to carry out simulation for four kinds of pole-slot matching BLDC including 12-slot with 8-pole, 12-slot with 10-pole, 12-slot with 14-pole, 12-slot with 16-pole. The result of theoretical analysis was verified, which provides theoretical basis for BLDC design.
