  • Patent number: 8049374
    Abstract: A mover assembly of a reciprocating motor includes: a mover body disposed at a gap between an inner stator and an outer stator; permanent magnets fixed at an outer circumferential surface of the mover body and reciprocally moved together with the mover body in a direction of an induction magnetic field between the inner stator and the outer stator; and a mixed member made of a fiber and a resin to cover and fix the permanent magnets. The permanent magnets are arranged at an outer circumferential face of the mover body, covered with the mixed member obtained by mixing a fiber and a resin, and hardened to be fixed. Therefore, the permanent magnets can be firmly and easily fixed at the mover body. In addition, by molding the mover body with a non-magnetic and non-conductive material, leakage of the magnetic force of the permanent magnets can be prevented.

  • Patent number: 6882075
    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.
