摘　　要：采用有限元数值方法分析了某大容量立式同步电动机的磁场分布规律,并完成了不同方案下的空载和负载工况反电势THD值以及转矩脉动和相关性能的计算。通过进一步的优化,确定了两种极数下电机的最优方案并进行了总结。The magnetic field distribution of the vertical synchronous motor with a large capacity is analyzed by finite element numerical method,and the THD value of the counter potential and the torque ripple and related performance under different schemes under no-load and load conditions are calculated.By the further optimization,the optimal scheme of the motor with two poles is determined and summarized.
