Abstract

A core lamination structure in a motor is constructed such that a plurality of lamination sheets of a predetermined shape are laminated to form a laminated body, that is, a unit lamination core. The unit lamination core formed by the plurality of lamination sheets is fixedly coupled by a caulking portion or a coupling portion formed on the respective lamination sheet and connected with the adjacent lamination sheets to be in a row. In this way, a fabricating process of the unit lamination core is made to be easy and simple to reduce time for fabricating, and a curvature for a curved surface portion of the unit lamination core can be changed so that the present invention can be applied to various motors according to the capacity or the size of the motor.

Description

technical field [0001] The present invention relates to a lamination method and a lamination structure of an iron core in a motor, in particular to a lamination method and a lamination structure of an electric motor core that enable the curvature of the lamination body to be changed and whose structure and manufacture are simpler, wherein the lamination The body is made by laminating a number of laminations and attached to the bobbin. Background technique [0002] Generally, reciprocating motors are made by changing the magnetic flux of a general-purpose motor with a spatial structure into a planar shape, that is, the moving part of the planar shape moves in accordance with the change of the magnetic flux formed on the fixed part of the plane Linear motion on a plane. [0003] figure 1 with figure 2 An example of a reciprocating motor is shown. As shown in the figure, the reciprocating motor includes: a stator S, which includes an outer core 10 and an inner core 20, the ...
