针对具有较大搜索空间的空芯永磁同步直线电机优化设计问题，提出了一种新的分析方法。其目的是用由非线性等效磁路和磁通密度分布模型组成的电机分析模型代替大部分的有限元分析步骤，以减少总的计算时间。使用少量的有限元步骤来确定分析模型的一些参数。将该方法的结果与纯有限元设计结果和实际电机上的实验结果进行了比较。该方法的性能与有限元分析相似，但在计算上至少快两个数量级。
This paper presents a new analysis method for air core permanent-magnet synchronous linear motor design optimization problems with a large search space. The aim is to reduce the total computational time by replacing most of the finite-element analysis (FEA) steps with an analytical model of the motor consisting of nonlinear equivalent magnetic circuit and flux density distribution models. A small number of FEA steps are used to determine some parameters of the analytical model. The result of the proposed method is compared with results of both a pure FEA design and experiments on a real motor. The proposed method has similar performance to FEA, although computationally it is at least two orders of magnitude faster.
