- 吸込口及び吐出口を有するハウジングと、
前記ハウジング内に軸線を中心として回転可能な状態で収容され、前記軸線の周りの回転により前記吸込口から前記吐出口に向かう流れを前記ハウジング内に生じさせる回転体と、
前記回転体側に設けられた磁性体、及び前記軸線の周りに並ぶようにして前記ハウジング側に設けられた複数の電磁コイルを含み、各電磁コイルがコンデンサを介して交流電源と接続されて共振回路が形成され、前記交流電源から前記共振回路に交流電圧が印加されて前記電磁コイルが励磁されることにより、前記回転体を前記ハウジングに対して非接触で支持する磁気支持手段と、
前記回転体を前記軸線の周りに回転駆動する駆動手段と、を備え、
前記複数の電磁コイルのそれぞれは、各電磁コイルが発生する磁束が前記回転体の内周側と外周側との間を当該回転体の半径方向に沿って流れるように設けられている磁気浮上式ポンプ。 - 前記磁性体は前記回転体の周方向に並べられた複数のセグメントを含み、前記複数のセグメント同士は互いに接しないように分離されている請求項1に記載の磁気浮上式ポンプ。
- 前記磁気支持手段には、前記回転体が前記軸線の方向に関して所定の位置にあるときの前記共振回路の共振周波数よりも高い周波数の交流電圧が前記共振回路に印加されるように前記交流電源からの交流電圧を変換する電圧変換手段が設けられている請求項1又は2に記載の磁気浮上式ポンプ。
- 前記複数の電磁コイルが複数のグループに分けて配置され、各グループに前記電圧変換手段が設けられている請求項3に記載の磁気浮上式ポンプ。
- 体外循環回路の血液ポンプとして構成されている請求項1〜4のいずれか一項に記載の磁気浮上式ポンプ。
