Diagnostics of career dump truck traction induction motors technical condition using wavelet analysis

In order to avoid unintentional disruption of the career transport system as a result of an unexpected career truck breakdown, many enterprises are moving to the maintenance system of the fleet according to actual condition. The possibility of using different diagnostic methods for determining the technical condition of traction induction motor was evaluated. The decomposition of the asynchronous motors diagnostic signals by wavelet analysis was regarded. Wavelet functions for analysis of non-stationary signals in vibration and spectrum-current diagnosis of induction motors were recommended. The possibility of diagnostic frequencies sampling using wavelet analysis was demonstrated.
