<p><P>PROBLEM TO BE SOLVED: To provide a laminated core that enhances the bonding strength between split-core blocks adjacent to each other, prevents the disassembly of the split-core block when carrying out the split-core block from a die, and facilitates winding and assembly after the winding in a laminated core formed into an annular shape by combining a plurality of split-core blocks, and to provide a manufacturing method for the core. <P>SOLUTION: The laminated core 10 is configured such that a split-core block 13 is formed by caulking and laminating a plurality of core pieces 15, 17; two or more split-core blocks are connected to each other by fitting-recesses 18, 19 and fitting-protrusions 20, 21 that are separable from each other and connectable to each other; and a concavo part 25 and a convex part 16 are provided at the contact part between the fitting recess 18 and the fitting protrusion 20 so that the concavo part and the convex part are engaged with each other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
