ABSTRACT:
A magnet fixing method of a linear servo motor wherein a cage for simultaneously securing positions and angles of a plurality of magnets is injection-molded where the cage is utilized to fix the magnets such that productivity is improved to shorten the working hours and reduce the manufacturing cost. A mutual twisting phenomenon can be prevented by interacting magnetic force among the plurality of magnets to thereby reduce the rate of defects.
