Claim Text:
1. A reciprocating motor, comprising: a stator having an annular shape; and a mover that reciprocates relative to the stator, wherein the stator comprises an inner stator positioned inside the mover and an outer stator positioned outside the mover, wherein the inner stator and the outer stator are integrally formed as a single body, wherein the stator is formed by radially laminating a plurality of blocks, each of the plurality of blocks being formed by laminating a plurality of stator cores, wherein each of the plurality of blocks includes a stator block having a coil receiving slot to receive a coil therein, the stator block having an open wall surface corresponding to one axial side of the coil and a pole block that forms a wall surface of the coil receiving slot and is coupled to the stator block to form an air gap along with the stator block, the pole block being coupled to the open wall surface of the stator block to form the air gap, wherein a plurality of air gaps is formed at one axial side of the stator, in which the mover is inserted to reciprocate, and wherein a plurality of magnets that forms the mover is disposed between an outer circumferential surface of each of the plurality of the air gaps and an inner circumferential surface of each of the plurality of the air gaps.
