摘要
针对Halbach永磁阵列提出了2种改进型Halbach永磁阵列,通过改变Halbach阵列的结构提高永磁同步电机的电磁性能,增加气隙磁通密度基波幅值和改善磁通密度波形的正弦性。设计了2台永磁同步电机模型,运用有限元分析比较两种新型双层Halbach阵列对气隙磁通密度、反电动势、转矩脉动、效率的影响,通过仿真结果与实验对比验证所提结构的合理性和正确性。
Two modified Halbach permanent magnet arrays were proposed for Halbach permanent magnet arrays.The electromagnetic performance of the permanent magnet synchronous motor was improved by changing the structure of the Halbach array,the amplitude of the fundamental flux of the air gap and the sine of the flux density waveform were improved.By designing two permanent magnet synchronous motor models,the effects of two new double-layer Halbach arrays on air gap magnetic flux density,back EMF,torque ripple,and efficiency were compared using finite element analysis.The rationality and correctness of the proposed structure were verified by simulation results and experiments.
