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.
