摘要：
This paper develops an improved stator current based detection scheme for bearing fault in induction motors. Firstly, experiments of bearing fault are performed. Secondly, by thoroughly analyzing the experiment results, a series of interesting highlights, which could help improve the sensitivity and reliability of stator current based detection of bearing fault in actual field, are revealed clearly. Finally, an improved stator current based detection scheme, which perfectly blends subdivision Fourier transform, self-adaptive filter and rotor slot harmonies based slip estimation techniques together, is proposed. Fault detection instances in laboratory demonstrate that the presented scheme is effective.
