PROBLEM TO BE SOLVED: To provide a reciprocal motor, which can improve the performance by minimizing the interference between magnetic fluxes due to a plurality of magnets provided, and can also reduce the amount of use of the expensive magnet. SOLUTION: The reciprocal motor is constituted with a multiple outer core 100, including of a plurality of single cores 120, 130 forming a hollow cylindrical structure by continuously laminating laminations K, K' around the center of a plurality of winding coils 110, 110' formed in a ring shape and a magnetic insulation member 150 provided between the single cores 120, 130, an inner core 200 inserted to the multiple outer core 100 having a predetermined gap apart from the internal circumferential surface of the multiple outer core 100, and a plurality of magnet trains 320, 320' corresponding to each winding coils 110, 110' of the multiple outer core 100, moreover including a moving element 300 for conducting the reciprocal movement between the multiple outer core 100 and the inner core 200, depending on the change of the current flowing into each winding coil 110, 110'.
