Diagnosis of Induction Motors Electrical Faults Using a Current Park's Vector Pattern Learning Approach
WU Zheng-guo · 2002
Park transform is applied to the malfunction diagnosis of induction, motor, avoiding complicated technology of frequency analysis. The current Park′s vector diagram of current signal of stator serves as malfunction characteristic of motor. And the malfunction Characteristic is sorted and correctness identified by artificial of nerve net technology. The experiment results has showed that the correctness of motor malfunction by this method identifying is very high. So it is a feasible method of motor malfunction diagnosis.
