Abstract:The Halbach array structure was innovatively applied to the orientation structure of the injection mold of the anisotropic ferrite multi-polar magnet ring for the contrastive study of the ordinary radial oriented structure and Halbach array oriented structure.With the assistance of the finite element software simulation,the magnetic field nephogram and the wave distribution of the magnetic field intensity for two different orientational structures were obtained.The results show that the magnetic field strength of the new orientation structure with Halbach array increases significantly.The structure is relatively unique and feasible,which can effectively solve the problem of insufficient orientation in the injection molding process of the anisotropic ferrite multi-polar magnet ring.
