A linear motor comprises a primary part and a secondary part opposite to each other. An air gap is reserved between the primary and secondary parts. The air gap has first spacing in non-operating state and second spacing in operating state. The side surface of the primary part facing the secondary part is provided with a magnetically conductive film that has elasticity in the thickness direction and a thickness greater than the first spacing and less than the second spacing. The magnetically conductive film comprises magnetically conductive base bodies and non-magnetically conductive base bodies alternately distributed along the surface of the magnetically conductive film, and the magnetically conductive base bodies are filled with magnetically conductive materials. The magnetically conductive base bodies cover magnetic poles on the side surface of the primary part facing the secondary part, and the non-magnetically conductive base bodies shield gaps between the adjacent magnetic poles.
