项目摘要
The use of computer software for the design of electrical machinery is now almost universal. The finite element method (FEM) and the boundary element method (BEM), which have entirely different features from each other, are very useful for computer numerical analysis. In the analysis of general motor, the FEM suits the analysis of a complicated region which includes teeth, slots, and magnets, and so on. On the other hand, the BEM is useful for analyzing the electromagnetic quantities caused by rotation without remeshing in the FEM.The hybrid finite element and boundary element method (FE-BE) method that possess the advantages in these methods is also useful.In this research, we first investigated several basic study for accurate analysis by FEM,BEM,and FE-BE method. And than, taking account of the advantages in both methods, we apply the hybrid FE-BE method to the analyzes of several electrical machines, which are researching in our laboratory : linear induction motor (LIM), linear synchronous motor (LSM), and permanent magnet type synchronous motor (PMSM) having plural sub-magnets for one pole. By investigating the characteristics of the motors, we could obtain some optimal motor constructions. In addition, taking account of external voltage sources, we also derived an optimal block feeding conditions in single-sided LIM.The adequacy of the analysis results were confirmed by experiment.
现在使用计算机软件来设计电机几乎是普遍的。有限元方法和边界元方法具有完全不同的特点,在计算机数值分析中具有重要的应用价值。在一般电机的分析中,有限元方法适合于分析包含齿、槽、磁体等复杂区域。另一方面,边界元方法可以用来分析有限元中旋转引起的电磁场,而有限元和边界元混合方法(FE-BE)则具有这些方法的优点。然后,考虑到这两种方法的优点,我们将混合有限元-边界元方法应用于我们实验室正在研究的几种电机:直线感应电机(LIM)、直线同步电机(LSM)和单极具有多个子磁体的永磁式同步电机(PMSM)。通过对电机特性的研究,可以得到一些优化的电机结构。此外,在考虑外部电压源的情况下,还推导出了单边直线电机的最优分块馈电条件,并通过实验验证了分析结果的正确性。
