摘要：
The fault analysis of defective induction motors based on discrete fractional Fourier transform is presented in this paper. Firstly, the accelerometer is used to measure the vibration signals of induction motors running online. Secondly, discrete fractional Fourier transform is applied to analysis the vibration signals with transformation angle from 0 to pi/2. A 3D feature spectrum is then built for further fault analysis. Finally, a comparison is made between a healthy, damage-free induction motor and motors with three common defects, broken rotor bars, damage to outer bearing ring and damage to inner bearing ring to achieve encouraged results.
