摘　　要：针对空气净化器电机用多极磁环的技术要求，采用铁氧体干压粉料生产多极磁环。介绍了整个工艺过程，重点阐述了利用有限元分析软件设计的永磁取向器结构及其磁通密度分布。实测结果表明，该方法制作的永磁取向器磁通密度峰值（8个极）为8450～8650G。以此制备的8极多极磁环具有良好的正弦波磁通密度分布，磁通密度峰值处于1794~1833G之间，平均值为1820G，满足设计要求。According to technology requirement of multipole magnet ring for air purifier motor,multipolemagnet ring was produced using dry ferrite powder.Technological processes were introduced,with emphasis onorientation circuit permanent magnet and its magnetic flux density distribution.Results show that the magnetic fluxdensity peak(8poles)of orientation circuit is in the range of8450to8650G.The multipole magnetic ring has good sinewave magnetic flux density distribution and the magnetic flux density peak between1794and1833G,meeting thedesign requirement.
