Abstract
【解決手段】この装置は、アーマチュア(11)に面して位置された負荷支持面(45,46)を有する第1のステータ(42)内に配設された主電磁コイル(43)を備えた少なくとも1つの駆動アキシアル磁気ベアリング(40)を有している。ロータの軸方向の位置を検出するためのディバイス(35)が、主電磁コイルを流れる電流をサーボ制御するための回路と関連付けられている。補償コイル(47)が、主電磁コイル近くで、前記負荷支持面から離れた位置に配設されている。この補償コイルは、主電磁コイルと直列に接続されているが、主電磁コイルを流れる電流とは反対の方向に電流が流れる。この装置は、磁気漏れを起こすことなく、最も好ましい容量のアキシアルベアリングを構成している。
