High Resolution based Bearing Damage Identification in Poly Phase Asynchronous Motor using Gabor Transforms of Stator Current

This paper proposes an advanced fault detection technique for polyphase induction motor via motor current spectral analysis. In this, induction motor safety is of high priority due to its massive usage in industries worldwide. Their benefits like more reliable, cost-effective, robust, and more efficient, etc. The motor current is disengaged from the induction motor to get frequency domain analysis using Gabor Transforms(GT) good resolution technique. Moreover, the non-stationary nature of the stator current is tested with different speed conditions at loads 1 and 2. Mainly these methods are used to run over the resolution problems, which are analogous to current signature analysis. Here Gabor transform detects the faults and locates dominating frequencies of the induction motor. The proposed scheme is verified on a 1.5 KW induction motor experimentally.
