“…However, this option may not be economically viable due to the incremental costs associated with the purchased motor and driver that feeds with a single to three‐phase power supply [11]. Both replacement options require an extensive amount of energy and materials to manufacture, resulting in a considerable environmental impact [12].…”

Induction motors, particularly single‐phase induction motors (SPIMs), represent the major consumption of power in the household sector. SPIMs that fail during their life cycle represent the best opportunity to improve their efficiency by replacing or repairing them. Although replacing faulty motors with new and efficient ones results in significant energy savings, this replacement is uneconomical due to its high initial costs. Additionally, this option requires extensive energy and materials to manufacture, resulting in a considerable environmental impact. This article aims to introduce a three‐phase rewinding of a failed SPIM using a rewinding algorithm that significantly improves the machine's efficiency and performance in an economically viable way. The 0.75 HP single‐phase capacitor‐start induction motor has been rewound to convert it into a three‐phase motor with the required 110 V line voltage and 50 Hz frequency. The economic analysis implies that the rewound machine's life‐cycle cost is 6% and 18% lower than the purchased SPIM IE1 and existing SPIM by below efficiency class respectively. The rewound motor achieves a payback period of 1–1.6 years for different motor loading levels, based on the world average electricity price, indicating an economically viable solution.

“…Therefore, the energy efficiency is of utmost importance, and the application of variable frequency drives should be able to provide it. Energy efficiency is rapidly becoming an imperative, also due to recent standards which may force the redesign of the electric machines [10]. In turn, the control technique plays a crucial role in the energy efficient operations of the electric drive.…”

This paper discusses the Maximum Torque Per Ampere (MTPA) control of synchronous motors, which have become an indispensable part of highly-efficient motor drives. It explains the nature of torque produced by synchronous motors, ways to find its maximum and algorithms to operate at this point, despite changes of loads and motor parameter variations. The authors propose a classification of the MTPA methods, based on the features of each algorithm or group of similar methods. They demonstrate the conventional control scheme and discuss the modifications necessary for the implementation of each method. This paper reviews existing maximum torque per ampere control algorithms, discusses their pros and cons and suggests possible areas of usage for each group of methods. The authors of the paper share their vast experience in the industry and research aspects, which were obtained by developing industrial, commercial, traction and military drives, and report on their views on the perspective of each method taken into consideration.

“…Whenever a machine transforms energy from one form to another, and this combined with power quality disturbances in the electric grid yields an unavoidable loss in the equipment, it is normally manifest as an increase in the temperature and an efficiency reduction [8,9]. Therefore, since the electrical machines use a significant part of the total electric power generated worldwide and its performance impact directly in the productivity costs, any improvement in its operation and control that increases its efficiency will have a meaningful impact [10][11][12][13].…”

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.
