【摘要】：双凸极永磁型双定子(DSPMDS)电机是针对电动汽车(EVs)驱动电机的应用要求,融合了双定子电机理论和定子永磁型双凸极电机理论,具有高转矩密度、高功率密度以及更加灵活多变的工作模式等优点。针对该电机双层气隙、双定子的复杂结构,在DSPMDS电机初始设计尺寸的基础上,通过建立电机参数化模型,并采用多目标敏感度优化方法,筛选出对电机转矩波动和铁心损耗影响最大的关键结构尺寸参数,在此基础上进一步采用响应面法选取最优结构尺寸参数。采用有限元仿真计算分析DSPMDS电机的反电动势、铁心损耗、定位力矩等电磁性能,样机实验结果验证了所提出的参数敏感度优化设计方法和性能分析的正确性,丰富了该类复杂结构的永磁型电机的快速设计和优化的途径。
[Abstract]:Double salient permanent magnet double stator DSPMDS (double stator permanent Magnet) motor is a high torque density motor, which combines the theory of double stator motor with the theory of stator permanent magnet doubly salient motor to meet the application requirements of electric vehicle EVS drive motor.High power density and more flexible working mode and other advantages.In view of the complex structure of double-layer air gap and double stator of the motor, based on the initial design size of DSPMDS motor, the parameterized model of the motor is established, and the multi-objective sensitivity optimization method is adopted.The key structural parameters which have the greatest influence on the torque ripple and core loss of the motor are selected, and the optimal structural dimension parameters are further selected by using the response surface method.The electromagnetic properties of DSPMDS motor, such as back EMF, core loss and positioning torque, are analyzed by finite element simulation. The experimental results of the prototype verify the correctness of the proposed parameter sensitivity optimization design method and performance analysis.It enriches the ways of fast design and optimization for this kind of complex permanent magnet motor.
