摘　　要：本文考虑到了永磁电机磁路较为饱和及永磁体工作点变化等特点,将交流电机的多回路理论与电磁场的有限元方法结合起来建立了多相永磁电机的多回路一有限元数学模型,并设计了九相永磁同步电动机的调速系统,经过仿真分析和实验验证表明,所建的多相永磁电机的多回路-有限元数学模型是正确的,设计的电机调速系统是有效的。In this paper, the multi-loop theory of AC machines and the finite element method of electromagnetic field are combined to form the multiphase permanent magnet machines' mathematical model which considers the magnetic saturation and permanent magnet's work point changing and the speed modulation system of nine-phase permanent magnet machine is designed. Based on the model and the system,the simulation of the nine-phase permanent magnet machine performance is carried out. The test result shows that the mathematical model is correct,and the speed modulation system is available.
