The invention relates to means and methods by which a rotor is rotationally journalled relative to a stator in a magnetic field provided concentrically about a longitudinal axis, coincident with the rotor and the stator axis such that an annular gap is formed between the rotor and the stator. A flexible, sheet metal foil of non-magnetic and electrically conductive material is arranged for insertion in the annular gap in relative rotation to the rotor. The foil is shaped for generating a fluid film in cooperation with the revolving periphery of the rotor,...
1. A fluid film bearing, comprising a sheet metal foil arranged to be interposed and to extend axially and concentrically in an annular gap that is formed between a rotor and a stator in contact-free relative rotation concentrically about a common longitudinal axis, whereinsaid sheet metal foil is made from a non-magnetic and electrically conductive, flexible material, and at least one magnet arranged for generating a magnetic field concentric about said longitudinal axis, the sheet metal foil supported in the magnetic field and effective to counteract o...
