1. INTRODUCTION
An Induction motor is the main source of mechanical power in almost every industry
including sugar, fertilizer, packing, agriculture lands, domestic and commercial water
supply schemes, water ltration, RO plant, locomotives etc. Apparently, induction motors
are widely accepted in industrial processes as well due to its robustness, cost eectiveness,
capability to operate in rough environment and less error chance (Pandey, Zope, &
Suralkar, 2012; Mortazavizadeh & Mousavi, 2014; Nandi, Toliyat, & Li, 2005; Soother
& Daudpoto, 2019). However, like other motors induction motor also faces several faults
due to its operating environment and usage conditions. Most of the faults are due to load
variations and improper power supply arrangements (Nandi et al., 2005; Soother, Daudpoto,
& Shaikh, 2018).
There are many electrical and mechanical faults related to both stator and rotor. Most
described faults in the literature related to the rotor are bearing faults, broken rotor and end
rings faults, and air gap eccentricity faults (Nandi et al., 2005; Mortazavizadeh & Mousavi,
2014). The faults related to the stator are imbalance in the supply phase voltages, under or
over voltage, single phasing condition, reverse phase sequence and inter turn short circuit
fault etc. (Nandi et al., 2005; Mortazavizadeh & Mousavi, 2014).
Presently much work is reported in this area to nd, isolate and identify dierent types of
the faults and avoid plant shutdown i.e., health of the motor is diagnosed by monitoring
certain parameters. The parameter may be the vibration, torque, ux, temperature, current
etc. (Mortazavizadeh & Mousavi, 2014; El Bouchikhi, Choqueuse, & Benbouzid, 2015).
The condition monitoring makes it possible to detect any abnormal behavior in the motor
at an early stage so that any big loss can be avoided (Gao, Cecati, & Ding, 2015). After
observing any abnormal condition, the necessary preventive maintenance strategies can
be applied for the removal of faults Unlike corrective maintenance strategy in which
correction applied after fault has gone through motor and motor operation is disturbed
(Mal et al., 2020; Ujjan et al., 2020). In this case, motor may be seriously damaged and can
cause unrecoverable loss to the plant.
Many researchers have been working in the eld of condition monitoring for fault detection
and identication using dierent fault diagnoses schemes including vibration, thermal,
