【Abstract】 A modeling method of the broken bar fault of the induction motor rotor was proposed based on the multi loop equation of the induction motor. On the basis of this modeling method,combined with parameter identification and sliding window technology,the change curve of equivalent parameters of induction motor can be obtained. Compared with the normal model equivalent parameters,the change curve of equivalent parameters has obvious characteristics,which can be used to diagnose the broken bar fault of induction motor rotor. The validity of this method was verified by experiments.更多还原
