Abstract: Embodiment of the present invention provides a cylindrical composite permanent magnet and a magnetic assembly including the same, wherein the cylindrical composite permanent magnet comprises at least one annular permanent magnet having a first magnetic parameter value and at least one annular permanent magnet having a second magnetic parameter value, wherein the at least one annular permanent magnet having the first magnetic parameter value and at least one annular permanent magnet having the second magnetic parameter value are jointed to form the cylindrical composite permanent magnet. The cylindrical composite permanent magnet in the invention is obtained by jointing at least one annular permanent magnet having the first magnetic parameter value and at least one annular permanent magnet having the second magnetic parameter value; the magnetic property of the cylindrical composite permanent magnet can be adjusted by selecting the material type and length of the joint annular permanent magnet.

Abstract: The invention relates to the field of permanent magnet materials, and discloses a composite permanent magnet material. The material is formed by splicing at least one permanent magnet material, with binding agent in between. The novel composite permanent magnet material that is formed by splicing different magnets greatly enriches the existing permanent magnet system and can completely replace the expensive rare metallic magnetic material. The composite permanent magnet material disclosed by the invention has high performances. The magnetic performance of the magnet can be regulated and controlled by adjusting the type and length of the magnets. In particular, the magnetic blank between the bonded NdFeB and the sintered NdFeB provides the designer and user of permanent magnetic motors with broader and flexible in material selection space and cost selection space.
