Title:
【発明の名称】磁気軸受システムとバックアップ軸受とセンサとを備えた真空ポンプ
Document Type and Number:
Japanese Patent JP2002513456
Kind Code:
A
Abstract:
A vacuum pump a the magnetic bearing assembly includes the magnetic bearing assembly with rotor position sensors and backup bearings being placed inside the rotatable shaft of the vacuum pump. The sensor placements are independent of the bearing position, so that the respective radial sensors can be at the same axial position as the respective radial bearings, which provides sensors co-location and a space saving within a turbopump housing, in particular, in its axial direction, while sensors and mechanical backup bearings are placed in a better protected area with respect to pumped corrosive gases.
