Induction motor plays an important part in many industrial processes. Detection of motor faults in the early stages improves process productivity, minimizes motor damage, and reduces repair costs. In this paper, a new method is proposed to detect broken rotor bars in a cage induction motor around the rated rotating speed. In this method, first, a frequency analysis is performed according to rotor bar's conditions and the characteristic frequency components are extracted. Further, a two-step diagnosis method based on self-organizing map, which is one of the classification methods, is proposed. Finally, the effectiveness of the proposed diagnosis method is verified by performing some experiments.
