One fault diagnosis method for electromotor based on BP neural network was proposed，and the network structure was designed for this diagnosis system. The simulation result indicates that the net structure has mush faster learning speed and more superior learning precision compared with other algorithm. It is entirely practical for the fault diagnosis system of the electromotor.   Key words： Artificial neural network； Electromotor； Fault diagnosis system； Pattern recognition； Pattern classification   Editor：liyan
