摘　　要：双定子永磁无刷(DS-PMBL)电机因其转子轭部主磁通变化易受各类参数影响而具有较高的研究价值。表贴式串联磁路DS-PMBL电机转子轭部主磁通具体由径向和周向磁通组成,归纳分析了两类磁通的成因及特点,并采用改变极弧系数和增设减重孔的方式对原模型进行优化。最终优化后模型的性能通过了有限元软件仿真验证。The Dual-Stator Permanent Magnet Brushless（ DS-PMBL） motor with surface-mounted series magnetic circuit has great study value by its changeable flux. The major magnetic flux is made up of axial and radial flux. The causes and characteristics of two kinds of flux were analysed,and by altering pole embrace and adding weight reduction hole to optimize the model. The model＇s performance was validated by finite element analysis.
