There is provided a method for measuring a laminated iron core. The method includes preparing a laminated iron core in which two or more kinds of metal plates with different shapes are laminated and a deformed part is formed inside a hole continuing in a lamination direction of the laminated iron core, acquiring a surface profile data indicating a surface shape of the deformed part through an inlet of the hole by a non-contact sensor located in an outside of the hole, and calculating a length from the inlet of the hole to the deformed part in the lamination direction by a calculator based on the surface profile data.

A method of manufacturing a laminated iron core includes extruding resins from a plurality of plungers toward a plurality of through holes extending from an upper surface to a lower surface of a laminated body formed of a plurality of electromagnetic steel plates to fill the plurality of through holes with the resins. The plurality of plungers are mutually independent and an extrusion amount of the resin is controlled for each plunger.

Method and apparatus for manufacturing laminated iron core

A method of manufacturing laminated core segments including: a process to blank and laminate, wherein the segment core sheets formed in the adjacent virtual lines are aligned so that directions of the segment core sheets alternate, each of the segment core sheets are blanked and formed by a die device, and the laminated core segments are formed by laminating the blanked segment core sheets in the die device; a process to eject, wherein each of the laminated core segments formed by blanking and laminating in each virtual line is ejected from the die device; and a process to identify a blanking position, wherein the distinguishing marks are provided for the laminated core segments to identify the virtual lines therefor.
