A stator structure of a reciprocating motor is provided. In the stator structure of a reciprocating motor, a bobbin around a coil is wound; a plurality of unit stacked core members of a predetermined thickness, each of which is formed by stacking a plurality of lamination sheets formed of predetermined shaped thin plates, and radially positioned on the outer circumference of the bobbin; and an injection insulator combining the plurality of unit stacked bobbins to an outer circumference of the bobbin. Accordingly, it is possible to reduce the number of parts that form the stator and to simplify the structure of the stator. Therefore, it is possible to reduce the time required for assembling the parts and reduce the processes of assembling the parts, to thus improve assembly productivity.

1. A stator structure of a reciprocating motor, comprising: a bobbin, around which a coil is wound; a plurality of unit stacked core members of a predetermined thickness, each of which is formed by stacking a plurality of lamination sheets formed of predetermined shaped thin plates, and radially positioned on the outer circumference of the bobbin; and an injected insulator, combining the plurality of unit stacked bobbins to an outer circumference of the bobbin, said injected insulator being injected into only edges where the unit stacked core members contact the bobbin, to combine the unit stacked core members with the bobbin. 2. The stator structure of claim 1, wherein each of the unit stacked core members includes two symmetrical division-type stacked core members. 3. The stator structure of claim 1, wherein a part of the outer circumference of the bobbin is exposed to allow contaminants inside the coil to be easily discharged.
