Abstract
Provided are a method and a system for detecting bend in the rotating shaft of magnetic bearing. The system comprises a first displacement sensor, a second displacement sensor, and a processor electrically connected with the first displacement sensor and the second displacement sensor; the processor comprises a calculating unit, a first judging unit and a second judging unit; the calculating unit is configured to calculate center positions of the rotating shaft stopping at different positions during rotating a circle; the first judging unit judges whether the rotating shaft is bent or not according to a curve of the changed center positions, and outputs a test result of qualification if the rotating shaft is not bent. Users are able to determine whether the rotating shaft needs to be processed or not, to avoid causing destructive effects on the magnetic bearing system due to excessive bend degree of the rotating shaft.
