| Abstract: | An improvement method of induction machine rotor fault diagnosis based on the stator-steady current and stator-start current of the machine is put forward in this thesis. To improve the resolution of the frequency and the amplitude of fault feature component, the frequency subdivision and the adaptive filter are used in processing the steady current of stator. With time-frequency analysis on stator-starting current, a new diagnostic method that using the special frequency component to diagnosis rotor winding faults is shown. This method has consumedly improved the reliability of fault diagnosis. At last the diagnosis system of rotor winding faults in induction motors is developed. |
