METHOD FOR OPERATING A FLUID CONVEYING DEVICE OF A MOTOR VEHICLE COMPRISING AT LEAST ONE AERODYNAMIC BEARING

摘要

The invention relates to a method for operating a fluid conveying device of a motor vehicle, comprising at least one aerodynamic bearing. The method comprises the steps: 1) reduction of the rotational speed of the aerodynamic bearing to a rest speed n0, wherein the rest speed n0 is below the lifting speed nlift, in which case the bearing builds up an air film for bearing free of mixed friction, and wherein the rest speed n0 is above a lowering speed nlow, in which case the bearing has reduced the air film such that mixed friction occurs; and 2) operation of the fluid conveying device having the rest speed n0.
