Abstract
A method of manufacturing a laminated core is provided. The manufacturing method includes the steps of feeding a belt-like sheet of core material to a progressive die, stamping out core pieces having a first shape from the core material, stacking more than one of the core pieces having the first shape to obtain a first laminate block, stamping out core pieces having a second shape from the core material, stacking more than one of the core pieces having the second shape to obtain a second laminate block, discharging a laminate including the first laminate block and the second laminate block from the progressive die, changing the lamination order of the laminate blocks constituting the laminate, and integrating the laminate after the lamination order of the laminate blocks are changed.
