The main purpose of this paper is to apply the extension method based on the spectrum of the vibration signal for motor mechanical fault diagnosis. The measured data of mechanical fault in induction motors are adopted to carry out the spectrum analysis and then establish the extension element model. According to the distance and the correlation function value concept of extension theory, one can calculate the correlation degree of various fault type and then determine the most possible category of mechanical fault in induction motors. Finally, some simulation and experimental results are made to verify the effectiveness of the proposed motor mechanical fault diagnosis method.
