Apparatus for error detecting of the rotary machine and Method for the same

摘要

The present application relates to apparatus for error detecting of the rotary machine and method for the same. The rotary machine according to an embodiment of the present invention includes: a measuring unit that measures rotational displacement and rotational speed; a convertor which converts the rotational displacement and the rotational speed into digital signal; an analysis unit which order analyzes size and phase of component signals that have frequency with integer multiple of rotary frequency by conversion of transactional flourier from the rotary displacement and rotation speed.
