PURPOSE: A mover is provided to prevent damages of the magnet by firmly fixing the magnet on the frame, while achieving improved efficiency of linear motor by minimizing the air gap formed between the inner and outer cores of the mover. CONSTITUTION: A linear motor comprises an inner core(12) radially arranged at the outer surface of a cylinder(17); an outer core(11) arranged with an air gap formed between the outer core and the inner core; and a mover(15) having magnets(14) coupled between the outer core and the inner core. The magnets of the mover are radially arranged into a cylindrical shape. The mover is constituted by a frame holder(15a), a T-frame, and a frame ring(15b) which are integrally formed through an injection molding process.
