PURPOSE:To prevent a sintered permanent magnet from cracking and to eliminate the removal of a shaft by integrating the cylindrical magnet and the shaft via thermosetting resin. CONSTITUTION:A cylindrical sintered permanent magnet 1 is mounted in a circular hole B of a jig A, a shaft 3 is inserted into the central hole C concentric with the hole B, and a cover 4 is coated. Then, the shaft 3 is inserted between the magnets 1, and resin 2 is filled from an inlet 5. After the resin 2 is filled, it is geled at 50-100 deg.C for 30-60min, and completely cured at 100-150 deg.C for 30-60min. Thereafter, the resin is cooled to the ambient temperature, the jig A is disassembled, and removed. |
