Abstract

外周部（１１）に形成された連結部（１２）で相互に結合された隣り合うセグメント鉄心片（１３）を有し、連結部（１２）を折り曲げて隣り合うセグメント鉄心片（１３）の側端部（１４）を合わせながら、連続した複数のセグメント鉄心片（１３）を螺旋状に巻回して積層した積層鉄心（１０）において、連結部（１２）の半径方向外側には、連結部（１２）の折り曲げ時に半径方向外側に形成される半径方向膨出部（１８）を積層鉄心（１０）の外側円内に収める凹部切欠き（１９）が設けられ、連結部（１２）の半径方向内側には、連結部（１２）の折り曲げ位置を形成する内側切欠き（２０）が設けられて、連結部（１２）の半径方向の幅を幅狭に形成し、連結部（１２）の折り曲げ前の半径方向の幅をセグメント鉄心片（１３）の厚みの０．５倍以上５倍以下にする。これによって、連結部（１２）の厚み方向の膨出の影響を受けることなく、高効率で高品質の製品を製造可能な積層鉄心（１０）及びその製造方法を提供する。
