Publikováno v: Mechanical Systems and Signal Processing. 84:584-597

The mixed eccentricity fault detection in a squirrel cage induction motor has been thoroughly investigated. However, a few papers have been related to pure static eccentricity fault and the authors focused on the RSH harmonics presented in stator cur

Publikováno v: International Journal of Electrical Power & Energy Systems. 62:110-117

Many researches deal with the detection of broken bar fault in three-phase induction motor, however in high-power applications the multiplication of phases number allows the segmentation of the power on more than three phases which reduces the price

Publikováno v: Frontiers in Energy. 7:271-278

A transient model for an induction machine with stator winding turn faults on a single phase is derived using reference frame transformation theory. The negative sequence component and the 3rd harmonic are often considered as accurate indicators. How

A New Approach for Broken Bar Fault Detection in Three-Phase Induction Motor Using Instantaneous Power Monitoring under Low Slip Range

Autor: Abdelmalek Khezzar, Mohamed El Kamel Oumaamar, Yassine Maouche, M. Boucherma

Publikováno v: International Journal of Electrical and Computer Engineering (IJECE). 4

The majority of research is about the detection of broken bar fault in three-phase induction motor at high slip. Thus, it becomes very interesting and demanding to detect faults in case of low slip range. In this study, a novel investigation of broke

Most of rotor related faults in three-phase induction motors are due to broken rotor bars and end-ring defects. Nowadays Inductions motors are more frequently used with inverters which make the diagnosis process more complicated. Furthermore, some ma
