| titleOfInvention | Winding core, manufacturing method of winding core and winding core manufacturing equipment |
| abstract | PROBLEM TO BE SOLVED: To reduce a core loss, reduce the amount of grain-oriented electrical steel sheet used, and obtain an iron core with the same or the same loss even when a highly available grain-oriented electrical steel sheet is used. Provided are a wound steel core, a method for manufacturing a wound steel core, and an apparatus for manufacturing a wound steel core. SOLUTION: The wound steel core of the present invention includes a portion in which a grain-oriented electrical steel sheet 1 in which a first bent portion 4 and a second bent portion 5 are alternately continuous in the longitudinal direction are stacked in the plate thickness direction. One or more of the laminated grain-oriented electrical steel sheets 1 is formed by applying elastic deformation to the first bent portion 4, and in the side view of the first bent portion 4, before and after the application of elastic deformation. The maximum value of | h1m-h2m | / L, which is an index of the difference in height of the first bent portion 4, is more than 0 and 0.100 or less. [Selection diagram] FIG. 7 |
