摘要
PURPOSE: An on-site complex abnormal diagnosis method of an induction motor is provided to allow a user to efficiently maintain the induction motor by diagnosing various kinds of fault.;CONSTITUTION: The characteristics of an induction motor are calculated from a vibration signal and a current signal(104). The feature values of a reference load rate are curved fitted and are calculated. The feature values of a breakdown characteristic map and induction motor are normalized(105). The feature of a group is extracted from the corrected feature values(106). The extracted feature is classified(107). The type of the problem is diagnosed in reference to the extracted value(108).;COPYRIGHT KIPO 2011
