摘要： A laminated iron core and a method for manufacturing the same are provided to secure the lamination strength of the respective iron core pieces thereof, and to provide good magnetic efficiency and to reduce a loss. In a laminated iron core including a first caulking section formed in an area thereof having larger magnetic flux density than other area and a second caulking section formed in the other area, the engagement area A of the recessed sub-sections and projecting sub-sections of the first caulking sections of divided iron core pieces adjoining each other in the laminating direction is set smaller than the engagement area B of the recessed sub-sections and projecting sub-sections of the second caulking sections adjoining each other in the laminating direction.

摘要： A method for manufacturing a laminated core is provided that makes positions of boundary parts of laminated blocks and improves an efficiency of a welding operation of the blocks. The above-described object is achieved by the method of manufacturing the laminated core 10 including a process that forms a plurality of blocks 12 having a plurality of welding parts 13 to 15 of different forms or colors at intervals of prescribed angles in the circumferential direction, a process that laminates the plurality of blocks 12 under a state that the blocks are rotated at intervals of the prescribed angles and a process that welds the welding parts 13 to 15 having the different forms or colors of the laminated blocks 12 to form integrally the plurality of blocks 12.
