目的
本文的目的是提出使用等几何分析（伊加）的电机模拟，以准确地表示它们的几何形状，并获得高精度和规律性的数值解。
设计/方法/方式
伊加利用非均匀有理b样条来参数化域和近似解空间。处理不同的定子和转子的拓扑结构，计算域被分成两个不重叠的部分上的麦克斯韦方程独立求解，并通过一个经典的施瓦茨区域分解计划互连。与传统的多项式有限元法（FEM）的结果进行比较。
结果
新的方法是可靠和有效的。所得到的解决方案的领域是在很好的协议，通过有限元方法得到的。伊加提供了比FEM更好的精度。
独创性/价值
将伊加与区域分解相结合应用于电机模型是一个新的和原创性的贡献。
Purpose
This paper aims to propose the use of isogeometric analysis (IGA) for the simulation of electrical machines to represent their geometries exactly and obtain numerical solutions of high accuracy and regularity.
Design/methodology/approach
IGA makes use of non-uniform rational b-splines to parametrise the domain and approximate the solution spaces. Dealing with the different stator and rotor topologies, the computational domain is split into two non-overlapping parts on which Maxwell’s equations are solved independently and are interconnected by a classical Schwarz domain decomposition scheme. The results are compared with the conventional polynomial finite element method (FEM).
Findings
The new methodology is reliable and efficient. The obtained solutions of the fields are in good agreement with the ones obtained by the FEM approach. IGA offers a better accuracy than FEM.
Originality/value
The application of IGA combined with domain decomposition to the model of an electric machine is a new and original contribution.
