Abstract

In this paper, fast Fourier transform, Hilbert transform and extended Park's vector algorithms are implemented for broken rotor bar fault diagnostics of a 22 kW inverter fed induction motor. The mentioned algorithms are initially explained in their mathematical point of view with the help of simulations and then implemented on the phase currents taken from laboratory setup of inverter fed healthy and faulty machines containing one, two and three broken rotor bars. The effects of faults and inverter-based harmonics are studied and a comparison of the techniques in some major attributes is presented.
