“…In this regard, recent works demonstrated that the presence of stator asymmetries, rotor problems, bearing faults, cooling system defects, or coupling system problems may yield important drops in the efficiency of the machine [35], which is a consequence that reinforced the importance of proper knowledge of the health of these machines. The fact of depending on multiple and complementary informational sources enables reaching a more accurate and robust conclusion of the integral motor health.…”

“…Among all types of electric motors available on the market, the most popular is the three-phase induction [ 1 , 2 ]. After all, this equipment stands out compared to others for having characteristics such as: high efficiency, simple construction, robustness, high starting torque, low maintenance, and convenient power–volume ratio [ 3 ].…”

Induction motors play a key role in the industrial sector. Thus, the correct diagnosis and classification of faults on these machines are important, even in the initial stages of evolution. Such analysis allows for increased productivity, avoids unexpected process interruptions, and prevents damage to machines. Usually, fault diagnosis is carried out by analyzing the characteristic effects caused by the faults. Thus, it is necessary to know and understand the behavior during the operation of the faulty machine. In general, monitoring these characteristics is complex, as it is necessary to acquire signals from the same motor with and without failures for comparison purposes. Whether in an industrial environment or in laboratories, the experimental characterization of failures can become unfeasible for several reasons. Thus, computer simulation of faulty motors digital twins can be an important alternative for failure analysis, especially in large motors. From this perspective, this paper presents and discusses several limitations found in the technical literature that can be minimized with the implementation of digital twins. In addition, a 3D finite element model of an induction motor with broken rotor bars is demonstrated, and motor current signature analysis is used to verify the fault effects. Results are analyzed in the time and frequency domain. Additionally, an artificial neural network of the multilayer perceptron type is used to classify the failure of broken bars in the 3D model rotor.

“…that may make the selection of high-efficiency motors (class IE4, IE5…) useless in the applications in which they intervene. In this regard, recent works proved that the existence of rotor problems, stator asymmetries, cooling system defects, bearing faults, or coupling system problems may yield important drops in the efficiency of the machine [4], which is a repercussion that reinforced the importance of a proper knowledge of the health of these machines. Despite electric motors being quite reliable machines in general (especially the induction motors that are the most widespread in industry), they are prone to suffer different types of failures.…”

Electric motors condition monitoring is a field of paramount importance for industry. In recent decades, there has been a continuous effort to investigate new techniques and methods that are able to determine the health of these machines with high accuracy and reliability. Classical methods based on the analysis of diverse machine quantities under stationary conditions are being replaced by modern methodologies that are adapted to any operation regime of the machine (including transients). These new methods (especially those based on motor startup signal monitoring), which imply the use of advanced signal processing tools, have shown great potential and have provided spectacular advantages versus conventional approaches enabling, among other facts, a much more reliable determination of the machine health. This paper reviews the background of this recent condition monitoring trend and shows the advantages of this new approach with regard to its application to the analysis of electrical quantities. Examples referred to its application to real motors operating in industry are included, proving the huge potential of the transient-based approach and its benefits versus conventional methods.
