Abstract
A method and an apparatus for detecting wear data of a protective bearing, which relates to the technical field of a magnetic suspension bearing, and includes: firstly, a displacement of a rotor is acquired in a current falling process; then, contact time between the rotor and the protective bearing is determined according to the displacement, and a rotation speed of the rotor at any moment in the contact time is acquired, and then current wear information of the protective bearing is determined based on the displacement and the rotation speed; finally, historical wear information of the protective bearing is acquired, and the historical wear information and the current wear information are added to obtain total wear information of the protective bearing, wherein the total wear information is used for reflecting a state of the protective bearing.
