On the basis of analysis of present fault diagnosis methods,this paper adopts Hilbert transform to study induction machine's broken rotor bars under different load.Compared with FFT,this method enjoys higher diagnosis accuracy and frequency resolution,overcomes influence of main frequency leakage from FFT and conducts fault diagnosis better.
