Concerning the manufacturing method of the laminated split type rare earth magnet for improving the performance of the motor for driving an electric vehicle, the material sintering step of sintering the magnet material molded into a large number of pieces of magnet material molded from the raw material of the rare earth alloy powder; Bonding lamination step of bonding and laminating a magnet material that is split into a plurality of parts; The edge part of the bonded and laminated magnet material is a polishing step of polishing rounded; The plating step comprising forming a plating layer for insulation or corrosion prevention on the surface of the magnet material; and in the material sintering step, the magnet material is split molded in the form of a bottom member, a plurality of middle members, a top member, or a pair of finishing members, a plurality of intermediate members, a connection member, Through the technical configuration of which the magnet material is split into a large number of parts, it is possible to precisely laminate and assemble the magnet material divided into a large number of parts, and prevent the glue insulation from leaking to the outer surface of the laminated magnet material, so that it can greatly contribute to the productivity improvement and cost reduction of the laminated rare earth magnet. |
