Abstract

隣り合うセグメント鉄心片１３を結合する外周領域１１の連結部１２を折り曲げ、セグメント鉄心片１３の端部を合わせながら、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、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２１を積層鉄心１０の外側円内に収める凹部切欠き２２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２３を設け、連結部１２を除くセグメント鉄心片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の収納凹部１６、１７を表裏に設ける。
