ABSTRACT:
A bobbin for a reciprocating motor and fabricating method thereof includes the bobbin comprising a bobbin body (310) including a first sidewall unit (312) and a second sidewall unit (313) forming a certain space in the body by extending at a certain height so as to have slopped part from both side of the bottom (311) having a ring form with a certain width; a winding coil (320) wound a plurality of times in the space of inner side of the bobbin body; (310) and a cover (330) couple to the bobbin body (310) so as to cover the winding coil (320), and a molding step for fabricating the bobbin, thereby fabrication of the winding coil and laminated outer core constituting the motor is simplified, the length of the permanent magnet constituting the mover can be shortened. So, fabricating cost of the motor can be reduced and mass productivity of the motor can be improved.
