The method of earlier stage fault intelligent prediction and diagnosis of three-phase equipments has been put forward based on expert system and neural network, by searching the parameters and signals that indicate the state of induce motor and analyzing their changing characters. Owing to the use the method, it is easy to detect early faults and separate a fault from others with the aid of powerful parallel processing and the non-linear reflective ability of intelligent measures of expert system and nerve network etc. So this realized earlier period faults intelligent diagnosis and prediction for induce motor.
