Abstract
The invention relates to an exhaust gas turbocharger () having a housing and having a shaft () which is arranged so as to be capable of rotating about its longitudinal axis in the housing and on which a turbine wheel () and a compressor wheel () are seated and which is guided in radial bearings () and in at least one axial bearing (), the radial bearings () being embodied as passive, permanent-magnetic bearings which each have a bearing plate () which is seated on the shaft () as a rotor, and at least one stator () which is disposed axially opposite to said rotor. In order to achieve a radial oscillation damping of the shaft () in a simple manner, it is proposed according to the invention that a resilient element () is disposed between the stator () and a part () which is fixed to the housing.
