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.
