Improving Legibility of Motor Current Spectrum for Broken Rotor Bars Fault Diagnostics

In this paper, the harmonic contribution of the broken rotor bar of an induction machine is investigated using an effective combination of the fast Fourier transform (FFT) and a band stop filter. The winding, spatial, grid fed and fault-based harmonics are investigated. Since the fundamental compone...
