“…În prezent, patru clase de eficiență sunt definite de standard, adică IE1, IE2, IE3 și IE4 și este de așteptat ca următoarea ediție să definească clasa de eficiență IE5. Din această clasificare, producătorii au prezentat diferite propuneri către obținerea unor eficiențe tot mai mari în motoarele electrice [15]. Având în vedere eficiența tot mai mare la motoarele electrice, ca urmare a implementării noilor tehnologii, au fost prezentate studii care compară diferite clase de eficiență în [16][17][18][19][20], beneficiile economice și tehnice.…”

One of the most common requirements in modern industrial applications is to minimize the costs associated with the operation, maintenance and possible repairs of the component systems. In industrial processes, induction motors are the most commonly used electromechanical converters in electrical drive systems. The extensive development of power electronics, as well as the relatively low manufacturing cost of asynchronous motors has determined a very high incidence of the presence of induction motor drive systems in industrial systems. The use of semiconductor devices to control the drive parameters of induction motors facilitates the tuning of the system and thus greatly improves its flexibility. However, the optimal use of such electric motors is limited due to the possibility of specific defects caused by the quality of the power supply. In this context, this paper proposes an analysis of the defects that frequently appear in the case of induction motors in industrial electrical drive systems as a result of deviations from the quality of the electrical energy of their power system parameters. Two deviations from the energy quality are mainly investigated, namely, the imbalance of the voltage value applied to the motor phases, respectively the harmonic distortions of the waveforms of the voltages applied to the motor. At the same time, an analysis of the failure rate is made according to various characteristics of the induction motors.

“…However, the industrial power supply is typically contaminated due to all the loads connected to the grid, and also their non-linear behavior because of its integrated elements that inject power quality disturbances (PQD) such as noise, sags, swells, interruptions, flicker, harmonics and inter-harmonic content affecting the PQ [41]. In the end, these PQ affectations are also reflected back on the electrical machines by decreasing their efficiencies, provoking malfunctioning and damage to their components [42]. Power electronics are an important part of any power conversion system.…”

The electric machines are the elements most used at an industry level, and they represent the major power consumption of the productive processes. Particularly speaking, among all electric machines, the motors and their drives play a key role since they literally allow the motion interchange in the industrial processes; it could be said that they are the medullar column for moving the rest of the mechanical parts. Hence, their proper operation must be guaranteed in order to raise, as much as possible, their efficiency, and, as consequence, bring out the economic benefits. This review presents a general overview of the reported works that address the efficiency topic in motors and drives and in the power quality of the electric grid. This study speaks about the relationship existing between the motors and drives that induces electric disturbances into the grid, affecting its power quality, and also how these power disturbances present in the electrical network adversely affect, in turn, the motors and drives. In addition, the reported techniques that tackle the detection, classification, and mitigations of power quality disturbances are discussed. Additionally, several works are reviewed in order to present the panorama that show the evolution and advances in the techniques and tendencies in both senses: motors and drives affecting the power source quality and the power quality disturbances affecting the efficiency of motors and drives. A discussion of trends in techniques and future work about power quality analysis from the motors and drives efficiency viewpoint is provided. Finally, some prompts are made about alternative methods that could help in overcome the gaps until now detected in the reported approaches referring to the detection, classification and mitigation of power disturbances with views toward the improvement of the efficiency of motors and drives.

“…In [1], the analysis of the oscillations caused by unbalanced loads in salient pole synchronous generators was highlighted, in order to identify and quantify the magnitude of the electromagnetic torque caused by unbalanced currents. In [2], it was presented a comparison of the harmonic response of three different efficiency classes of three-phase induction motors (TIM) in the presence of voltage harmonics and unbalance with voltage variations. In [3], an investigation of the influence of unbalanced and nonsinusoidal voltages on power factor definitions and measurement algorithms was made considering a constant impedance load and a TIM.…”

Many unbalanced voltage conditions, which produce different effects on electric equipment, are associated with the same voltage unbalance factor. This fact hinders the precise association between the values of this index and the effects of voltage unbalance. In the present study, an alternative methodology for quantifying voltage unbalance based on the effects of this phenomenon on the temperature and efficiency of three-phase induction motors is proposed. The application of the suggested methodology results in an index that contemplates the combined effects of the modules and angles of the positive and negative sequence voltages. Aiming to apply this methodology and evaluate its performance, we selected a comprehensive set of balanced and unbalanced voltage conditions and used it on a three-phase induction motor. The results show that the index obtained, when compared to the traditional voltage unbalance factors, reduces the uncertainties inherent to the quantification process of this phenomenon. In other words, it allows a better association between the values and effects of the voltage unbalance. For these reasons, this index is considered as a potential alternative that can be employed in industrial utilities and standards that deal with voltage unbalance.INDEX TERMS Efficiency, index to quantify voltage unbalance, induction motor, power quality, symmetrical components, temperature.
