Abstract
A method for manufacturing a permanent magnet includes preparing a plurality of permanent magnet blocks having the same size, spacing and arranging the plurality of permanent magnet blocks in a lower mold Having an opened upper side, pressing a side of the lower mold while circulating adhesive in the lower mold and integrating the plurality of permanent magnet blocks such that the adhesive is evenly applied to surface of each of the permanent magnet blocks, thereby forming a permanent magnet assembly and hardening the adhesive by heating the permanent magnet assembly.
