“…Time-demanding fault diagnosis of electric machines has been investigated to identify the indication of incipient failure symptoms to prevent catastrophic failures [2]- [4]. One of the promising diagnosis strategies in recent years has been known as motor current signature analysis (MCSA) [5], [6] as the motor signal is readily available from a motor control service routine without extra hardware or design cost [7]. The motor current signal provides superior information to the vibration signature in terms of error rate under different operating conditions such as speed [8] and load torque variation [9].…”

“…Generator bearing and eccentricity, as well as pinion gear faults, can automatically be detected through stator current analysis using information entropy [20], through an adaptive neuro-fuzzy inference system and particle filtering [21] or computing the energy from the fault-related frequencies [22,23]. The results are validated at laboratory benches for the studies in [20][21][22][23] and using simulated data in [24,25]. The main drawback of these approaches is the need for a healthy current baseline.…”

“…Research shows that it is of great significance to set a temperature protection limit and to increase the response speed of overheating failure protection for an induction motor [5], [6]. As a matter of fact, there are many factors that affect the accuracy and efficiency of the identification of temperature, such as the uncertainty of the harmonic order, the complexity of the motor parameters, and most of all, the stator voltage transient shock [7]- [11].…”
