The Spectral Leakage Minimization of Spectrum for Motor Fault Analysis using Adaptive Multi-Taper Method

摘要：

　　This paper proposes a new method of motor fault detection.Adaptive MTM is proposed as a key technique for motor fault analysis.Standard spectrum has always processed a time-signal into frequency domain with spectral leakage contamination.The leakage results important small harmonics to be invisible which makes the spectrum difficult to analyze the motor faults.The spectrum from the Adaptive MTM is introduced to minimize the leakages.The method is tested on 3 different motor conditions:healthy,stator fault,and rotor fault motor at full load condition.Based on several sets of the experiments,the spectrum from the adaptive MTM can show all the harmonics clearly which make the method more powerful for fault analysis.
