Approximation and Extrapolation of Vibrations in Induction Machines as a Function of Numbers of Short-circuited Turns in Stator Winding

The aim of the research was to extend the possibilities of monitoring and vibration diagnostics of electric machines. The authors proposed a non-invasive diagnostic method taking in to account multi-phase inter-turn short-circuits in stator winding. The process of acquiring of the diagnostic signal and proposed diagnostic method have been presented, concluded and discussed. Moreover, the developed method was verified and the error of the proposed method was calculated.
