Abstract

This paper develops a new model with adjustable accuracy to evaluate performance of permanent magnet Vernier machine (PMVM) based on flexible magnetic equivalent circuit (MEC) method. The desired machine parameters such as number of flux modulation poles (FMPs), winding pole-pairs, and geometrical dimensions can be chosen in the presented model. By utilizing nonlinear core magnetization curve, saturation effect is taken into account. There are two main contributions in this study. First, the flexible MEC model is developed to predict the machine performance accurately. The second contribution is that the developed model can be used to evaluate the performance of the machine under no-load and loading conditions at the same time. The results of MEC model under no-load and loading conditions are compared with 2D-finite element method (FEM) and 3D-FEM in terms of accuracy and simulation time. The results indicate acceptable accuracy and suitable processing time of the proposed MEC model.

永磁游标机的柔性磁等效电路建模与分析

基于柔性磁等效电路(MEC)方法，建立了一种精度可调的永磁游标机(PMVM)性能评价模型。在该模型中可以选择所需的机器参数，如磁通调制极数、绕组极对和几何尺寸。利用非线性磁芯磁化曲线，考虑了饱和效应。这项研究有两个主要贡献。首先，建立了柔性MEC模型，实现了对机床性能的准确预测。第二个贡献是所建立的模型可以同时用于评估机器在空载和有载条件下的性能。在空载和加载工况下，将MEC模型的计算结果与二维有限元法(FEM)和三维有限元法(3D-FEM)在精度和仿真时间上进行比较。结果表明，所提出的MEC模型具有可接受的精度和合适的加工时间。
