Abstract :
The use of efficient signal processing tools (SPTs) to extract proper indices for fault
detection in induction motors (IMs) is the essential part of any fault recognition procedure. In the
first part of the present paper, we focus on Fourier-based techniques, including fast Fourier transform
and short time Fourier transform. In this paper, all utilized SPTs which have been employed for
fault detection in IMs are analyzed in detail. Then, their competency and their drawbacks to extract
indices in transient and steady state modes are criticized from different aspects. Different kinds of
faults, namely, eccentricity, broken bar, and bearing faults as the major internal faults in IMs, are
investigated.
