The paper presents the design process of three-phase star winging of permanent magnet brushless DC motors. The winding connection among coils was confirmed by fractional-slot motor analytical calculations basing magnetic potential star graph and phase belt partitioned operation. Meanwhile, simulation results of common fault simulation applied to an 1.5 kW permanent magnet brushless DC motor prove the validity of fault simulation.%阐述了无刷直流永磁电动机星型三相绕组的设计过程,以磁势星型图作为分析计算分数槽电机的基础,通过相带划分法,确定线圈之间的连接方法.同时,以一台1.5 kW的无刷直流永磁电动机为例,模拟出线圈连接中常见的故障情况,与仿真得出的实验结果进行了比较分析,验证了故障模拟的有效性.
