Abstract

  発電動機一体型超電導磁気スラスト軸受において、第１固定コアは、円筒形状の中心軸方向の断面形状がコの字形状で、かつ、そのコの字形状の開口部が中心軸と垂直方向となるように形成され、超電導コイルは、コの字形状に形成された第１固定コアのコの字形状部分の内側に配置される。回転コアは、第１固定コアのコの字形状の２つの突端部に対向した位置に突端部を有し、且つ、電機子コアに対向する位置に超電導コイルの巻線方向に所定の間隔で形状変化を有する磁束誘導路を有し、第１固定コアに対して相対的に回転するとともに、第１固定コアの中心軸方向に移動可能に構成される。電機子コアは、超電導コイルで発生され第１固定コアのコの字形状の２つの突端部のうちの一方の突端部から導出される磁束を回転コアの突端部へ導入するとともに、回転コアの突端部から導出される磁束経路の中に固定配置されている。
