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.

Abstract: A stator for a reciprocating motor includes a bobbin made of an insulating material in which a winding coil is located; a terminal unit forming a single body with the bobbin and connecting the winding coil electrically with an outer power source; and a core unit stacked radially along with the bobbin started from one side of the terminal unit. Therefore, the winding coil and the bobbin can be coupled in simple way, and the core unit can be stacked simply and precisely, so the mass productivity of the motor is able to be increased. Also, the size of the core unit is able to be managed simply and precisely, and then, the contact and impact with other components constructing the motor is prevented, whereby the reliability of the motor can be improved.

Abstract: A stator of a reciprocal motor includes a bobbin of insulating material with a coil wound thereon, a terminal unit formed integrally with the bobbin to connect the coil to an external power source, a first lamination core in which a plurality of lamination sheets of a predetermined form are stacked radially along the bobbin, and a second lamination core in which a plurality of lamination sheets formed to have a certain width and length and located symmetrically on the central line in the direction of the length, are coupled with the inner side or outer side of the first lamination core. Therefore the present invention makes the laminating operation simple and convenient by laminating the plurality of lamination sheets composing the laminate core without sorting the lamination sheets in a certain direction during the production of the lamination core thus to improve assembly productivity and mass productivity.
