LAMINATED CORE, LAMINATED CORE MANUFACTURING METHOD, AND LAMINATED CORE MANUFACTURING APPARATUS

WIPO Patent Application WO/2024/054028

A1

One embodiment of the present invention provides a layered laminated core formed by laminating laminae, and a laminated core manufacturing method and laminated core manufacturing apparatus for same. The laminated core according to the present invention includes: a connection hole which is provided between and connects laminae provided side by side on one side and the other side of the connection hole, and into which a protrusion formed on the one lamina is inserted and penetrates in the thickness direction; and a plurality of connection laminae on which protrusions that are inserted into the connection hole penetrating the other lamina in the thickness direction are formed at different positions. According to the present invention, interference between laminae forming the laminated core can be minimized or eliminated, and thus the height deviations across different parts of the laminated core can be minimized and the parallelism, perpendicularity, and planarity of the laminated core can be improved.
