Document Type and Number:
WIPO Patent Application WO/2022/166138
Kind Code:
A1
Abstract:
A method for measuring wear data of a protective bearing, relating to the technical field of magnetic bearings. The method comprises: first obtaining the displacement of a rotor in the current falling process (S101); then determining the contact time period of the rotor and a protective bearing according to the displacement, and obtaining a rotation speed of the rotor at any moment within the contact time period (S102); then determining the current wear information of the protective bearing according to the displacement and the rotation speed (S103); and finally, obtaining the historical wear information of the protective bearing, and adding the historical wear information and the current wear information to obtain the total wear information of the protective bearing (S104), wherein the total wear information is used for reflecting the state of the protective bearing. Further provided are an apparatus for measuring wear data of a protective bearing, and a computer readable medium.
