齿槽转矩脉动是影响直流外转子电机输出转矩脉动的主要原因。为抑制齿槽转矩脉动,根据电机的结构参数建立了有限元分析模型,并对齿槽转矩进行仿真;仿真结果与试验获取的齿槽转矩曲线吻合较好,证明了所建模型的正确性。然后,采用Taguchi方法,以齿槽转矩峰值和平均输出转矩作为优化目标,以槽口宽度、极弧系数、气隙长度、平行齿宽为控制因子,选取槽口宽度加工误差、气隙长度加工误差、平行齿宽加工误差和永磁体剩磁变化作为噪声因子,对电机进行了优化设计,并利用所建立的有限元分析模型进行性能仿真验证。结果表明:用Taguchi方法优化电机设计参数,能够在电机平均输出转矩略有增加的同时,显著降低齿...

Cogging torque ripple is the main impact factor of the output torque ripple of electric vehicles driven by wheel hub motors. To suppressing cogging torque ripple, a DC external rotor motor was studied, and a finite element analysis model was established in Ansoft Maxwell according to its structural parameters. The simulation results of cogging torque agreed well with those obtained from experiments, and this showed the analysis model was correct. Then, the main parameters of the hub motor were optimized by using Taguchi method, in which the peak values of cogging torque and average values of o...
