Taking the single-phase power spectrum as the research object,the fault frequency fv is picked up in single-phase power spectrum by using EMD.The simulation results show that this method is highly sensitive and clear,successfully solving the problem of which fault component frequency of motor bearing is too close to basic wave to be separated in stator current.It is feasible to apply in fault diagnosis of motor bearings.
