This work deals with shape optimization of electric machines using isogeometric analysis. Isogeometric analysis is particularly well suited for shape optimization as it allows to easily modify the geometry without remeshing the domain. A 6-pole permanent magnet synchronous machine is modeled using a multipatch isogeometric approach and rotation of the machine is realized by modeling the stator and rotor domain separately and coupling them at the interface using harmonic basis functions. Shape optimization is applied to the model minimizing the total harmonic distortion of the electromotive force as a goal functional.

使用等几何分析和谐波定子 - 转子耦合的旋转电机形状优化

这项工作涉及使用等几何分析的电机形状优化。等几何分析特别适用于形状优化，因为它允许轻松修改几何形状而无需重新划分域。使用多面体等几何方法对 6 极永磁同步电机进行建模，通过分别对定子和转子域建模并使用谐波基函数在接口处耦合它们来实现电机的旋转。将形状优化应用于模型，以最小化电动势的总谐波失真作为目标函数。
