摘要
随着永磁电机向高效、节能方向的发展,电机设计标准和结构复杂度不断提高,对仿真设计的精确度和计算速度提出了更高的要求。为了提高电机设计的计算效率,本文提出了一种基于有限容积法(FVM)的电磁场计算方法,并将其应用于永磁同步电机的电磁设计中。通过从麦克斯韦方程组出发推导控制方程,分析了有限容积法在电磁场计算中的速度优势。本文开发了基于此方法的仿真工具,并将其应用于28极24槽永磁同步电机的设计与仿真计算。实验验证表明,该方法能够有效提高计算速度并保证较高的设计精度,与传统的有限元法(FEM)相比,FVM在大规模计算中具有更优的效率。通过样机制作与电磁性能测试,验证了该方法的有效性和工程应用的可行性。研究结果表明,有限容积法为未来永磁同步电机的高效设计提供了新的思路和方法,具有较强的工程实用性。
As permanent magnet motors advance toward higher efficiency and energy savings,increasing design standards and structural complexity place greater demands on both simulation accuracy and computational speed.To address these challenges,this paper proposed an electromagnetic field calculation method based on the Finite Volume Method(FVM)and applied it to the design of a permanent magnet synchronous motor.Starting from Maxwell’s equations,derived the governing equations and analyzed the computational speed advantages of FVM in electromagnetic field simulations.A dedicated simulation tool implementing this method was developed and used to design and simulate a 28-pole,24-slot permanent magnet synchronous motor.Prototype fabrication and electromagnetic performance testing confirmed that the FVM-based approach significantly enhances computation speed while maintaining high accuracy.Compared with the traditional Finite Element Method(FEM),FVM demonstrates superior efficiency in large-scale simulations.The results validate the effectiveness and practical applicability of the proposed method,offering a new engineering solution for the efficient design of future permanent magnet synchronous motors.
