Summary:A magnet fixing structure for a linear motor including a a plurality of magnets inserted into a magnet paddle connected to a piston, and a magnet fixing ring attaching the same onto the outer periphery of the magnets under pressure, includes a plurality of eddy current loss prevent slits formed in slant along the periphery of the magnet fixing ring, or a plurality of eddy current loss prevent pores formed along the periphery of the magnet fixing ring. The structure minimizes the widening of the slits which may be caused by magnet fluctuation, thereby improving motor efficiency.
