Optimal Design of Variable Sequential Combination for Transverse Flux Machine

针对横向磁场电机的复杂三维磁场及灵活多样的磁路结构,提出采用变量循序组合优化设计方法对其进行详细设计。该方法综合运用了试验设计方法、响应面分析法和变量轮换法,其关键是在设计过程中,依据严密的数学计算和优化对象本身的特性分析进行正确的变量循序组合。通过对爪极式组合定子横向磁场电机的优化实例表明,该方法在优化设计过程中充分考虑了所有结构尺寸对磁路的影响,适合横向磁场电机多变量多目标的优化详细设计问题,达到了电机的设计要求。

The variable sequential combination optimization design method was proposed for the design of transverse flux machine with complex three-dimensional magnetic field and flexible magnetic structure. This method integrated the design of experiment method, the response surface methodology and variable rotation method. The key issue of the method is that the optimizing object design is based on rigorous mathematical calculation and the analysis of its characteristics and gets correct variable sequential combination. The optimizing design was used to an assembled claw pole stator transverse flux machine as an example. The result shows that this method fully considers the impact of all structural dimensions on the magnetic circuit, it is suitable for solving multivariate and muhi-objective optimization design problems of the transverse flux magnetic machine, and it meets the design requirements of the machine.
