Abstract
A method for detection of rotor bar faults in an electric machine is provided. The method includes acquiring electrical signals from the electric machine that are representative of the operative condition of the machine. The symmetrical components from the electrical signals are eliminated by squaring an instantaneous value of each data point from the electrical signals and summing the squared values. The method further includes the step of eliminating discontinuities in the electrical signals by applying a window function to compute weighted representation of the squared values. Furthermore, the method includes the step of normalizing the weighted representation to obtain spectral information. The faults in the rotor bar are detected by analyzing the spectral information obtained after normalization.
