LAMINATED CORE, METHOD FOR MANUFACTURING LAMINATED CORE, AND DEVICE FOR MANUFACTURING LAMINATED CORE

WIPO Patent Application WO/2024/054085

A1

Disclosed in one embodiment of the present invention are a laminated core having a layered structure formed by lamination of laminas, a method for manufacturing a laminated core therefor, and a device for manufacturing a laminated core. The laminated core according to the present invention comprises adjacent laminas which are fixed while overlapped due to connection of a protrusion part and penetration part which form a pair, wherein the protrusion part is formed on any one of the adjacent laminas, and the penetration part is formed on another lamina to penetrate in the thickness direction thereof so that the protrusion part can be inserted thereto, and the protrusion part forms, on a plurality of layers of the laminated core, while inserted into the penetration part, a lamina laminated structure for connecting the adjacent laminas, and the penetration part has a piercing processed shape. According to the present invention, interference between the laminas can be minimized or resolved, and, thus, the height deviation of each section of the laminated core can be improved, and the parallelism, perpendicularity, and flatness can be improved.
