| Abstract: | In this paper,the method of cross power spectrum is used to simulate rotor bars breaking faults of induction motor,including continuous breaking and intermittent breaking of rotor bars.Results of numerical simulation show that it can diagnose the rotor bar breaking faults effectively in the conditions of low signal to noise ratio,so the approach has a good prospect in project appliance. |
