Abstract

外周領域（１１）の連結部（１２）で相互に結合されたセグメント鉄心片（１３）を連結部（１２）で折り曲げ、セグメント鉄心片（１３）の内周部又は外周部を合わせ、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、上下に隣接する層の連結部（１２）を周方向にずらしながら配置した積層鉄心（１０）及びその製造方法において、連結部（１２）の半径方向外側には、連結部（１２）の折り曲げ時に連結部（１２）が半径方向外側に膨出した半径方向膨出部（２０）を積層鉄心（１０）の外側円内に収める凹部切欠き（２１）を有し、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（２２）を設け、セグメント鉄心片（１３）の半径方向外側には、連結部（１２）の折り曲げ時にその厚み方向に形成される厚み方向膨出部（１５）の収容部（１６）を設ける。
