Streszczenie:

Maximising energy efficiency with electric motors Rukmi Dutta from the University of New South Wales discusses the mechanisms and efficiency potential of electric motor systems, looking at how electric motors work, efficiency and losses and improving overall system efficiency for electric motors. Increased industrial activities in developing economies like India, China, and many others will push the use of motors even further. Electrical motors are the powerhouse of the industrial world, she explains, discussing efficiently converting electrical energy into mechanical power. Many critical sectors use electrical motors, including industrial, commercial, residential, agricultural and transport. The worldwide growth of electrical motor-driven systems is predicted to double by 2040. Overall, UNSW Sydney’s Electrical Machines and Drive Systems research team is at the forefront and contributes to developing novel, highly efficient motors and drives suitable for many applications.

Streszczenie:

This paper, introduced an expression of Economic Efficiency Measure (EEM) to permit quick evaluation for replacement of faulty induction motor with alternative (new or refurbished motor) for lowest life-cycle cost based on efficiency and rated-load conditions. This approach, simplifies the process for evaluating the energy efficiency to mere proportionate factor called as EEM. During the operating phase, the motor losses correspond to extra energy consumption, based on various parameters like motor operating conditions, operating hours, operating costs, fault factor, depreciation factor and fixed costs. The approach is effective in addressing the global issue on replacement of the faulty motor that needs a comprehensive analysis and mathematical expression. Compared to other alternatives the EEM provides a simple but effective and reliable means to asses, the feasibility of replacing or refurbishing the faulty motor. A detail analysis here would establish how much the present approach is effective in determining the replacement for a faulty induction motor either by a new one or refurbished one of corresponding rating.

Line start permanent magnet synchronous motors (LS-PMSM) are preferred more and more in industrial applications, because they can start on their own and because of their high efficiency. In this study, a new LS-PMSM rotor typology is suggested, which is modelled using surface mount permanent magnets, in which two different slot types have been used together. The rotor of an asynchronous motor on the industrial market in the IE2 efficiency segment has been remodeled in the study, resulting in an increase in motor efficiency from 85% to 91.8%. A finite elements software was used for determining motor design and performance, in addition to analytical methods.

Streszczenie:

A three-phase induction motor absorbs the most electric power among other electrical loads. Therefore, three-phase induction motors are the primary electric motors used in industrial applications thanks to their simple construction and easy operation, as well as low cost and low maintenance costs. Efficiency is a critical parameter that characterizes an induction motor as a traction motor. The traction motor is defined as the engine's effectiveness in converting electrical power at its input into mechanical energy by rotating torque on its axis. One way to analyze the efficiency is to use test data obtained from laboratory tests in case-loaded and no-load tests. Calculations using several formulas on the efficiency of an induction motor as a traction motor produce the same result, namely the efficiency of 98.6% by applying variable frequency drive (VFD). The result of laboratory tests and their analysis can be used as a reference for designing three-phase induction motors for railway traction motors, especially traction motors for high-speed trains.

Brushless DC (BLDC) motors have a wide range of applications in these modern days, such as electric vehicles, industrial robots, washing machines, pumps, and blowers. The brushless DC motors have many advantages when compared to induction motors and conventional DC motors, such as better speed control, noiseless operation, high efficiency, less maintenance, and a long life. Along with these benefits, there is one major disadvantage known as cogging, which causes undesirable effects in the motor such as noises and vibrations. BLDC motors have been widely used in automation and industrial applications due to their attractive features. There are certain parameters to be considered while designing a BLDC motor, such as its dimensions, number of windings turns, type of magnetic materials used, required torque, output current, slot-to-depth ratio, efficiency, temperature rise, etc.

This paper presents a simulation method for the power consumption of servo motors, focusing on the influence of vibrations on the motor efficiency. An apparatus consisting of two servo motors connected through a coupling was specifically designed for this study. The efficiency of the servo motor was experimentally investigated for several torque vibration levels imposed through the selection of the control parameters, and the torque vibration level was quantified through the standard deviation of the torque signal. The efficiency map characteristics for each torque oscillating level were determined. A numerical model of the apparatus clarifying the dependency of the coupling characteristics on the oscillating torque was developed, and the torque oscillation of the system was simulated. A model based on the measured motor efficiency maps and the torque oscillation level was developed to simulate the motor efficiency under several torque vibrating conditions. Finally, the power consumption of the motor was simulated based on the simulated efficiency and mechanical power. A balance of input, output, and loss powers was presented, and the experimental measurements were compared with the simulation results. The power consumption of the motor increased when the torque oscillated owing to vibrations, and the loss of power due to both oscillations and the loss of motor efficiency was quantified.

Abstract Asynchronous motors are commonly utilized in industrial and agricultural production due to their inexpensive manufacturing cost and reliable structure. However, due to the demands of production and everyday usage, these motors may be operated at no or light load for long periods of time, resulting in a decrease in the efficiency of the motor system. A model-referenced adaptive parameter identification in combination with a particle swarm algorithm is proposed in this paper to enhance the operating efficiency of asynchronous motors. This control strategy can reduce motor power loss and improve efficiency. Simulation model is established and simulation results are provided to verify the feasibility of the proposed control strategy for optimizing the efficiency of asynchronous motors.

Streszczenie:

Although three-phase induction motors are the most common motor type in industry, a growing interest has arisen in emerging electric motor technologies like synchronous reluctance motors and permanent magnet motors. Synchronous reluctance motors are a step forward compared to permanent magnet motors when the cost of the system is considered. The main focus of this study is low-power industrial applications, which generally use three-phase induction motors. In this study, the synchronous reluctance motor family is compared at three different power levels: 2.2 kW, 4 kW, and 5.5 kW. The aim of this study is to design and compare synchronous reluctance motors, which can be alternative to the reference induction motors. Finite element analysis is performed for the reference induction motors initially. Their stators are kept the same and the rotors are redesigned to satisfy output power requirements of the induction motors. Detailed design, analysis, and optimization processes are applied to the synchronous reluctance motors considering efficiency, power density, and manufacturing. The results are evaluated, and the optimized designs are chosen for each power level. They are prototyped and tested to measure their performance.

Various industrial electric motors use a combination of internal and external fans to remove internally generated heat. In recent years as the electrical efficiency of motors has improved, the power drawn by the cooling fans has become a large percentage of the total motor losses. This paper presents an optimization approach to the selection of the cooling fan dimensions. The design objective is to obtain minimum power input to the fans while maintaining adequate cooling capacity. To illustrate the method, the cooling fan design for a 30 hp, 3600 rpm, a-c motor is considered. The optimal fan dimensions result in a 70 percent reduction in fan power.

O presente trabalho objetiva, a partir de dados coletados dos motores elétricos em regime de trabalho, dar sua contribuição ao estudo de conservação de energia elétrica numa planta industrial. Apresenta-se o motor elétrico trifásico de indução e as diversas questões relativas ao seu uso industrial, para então, demonstrarem os parâmetros elétricos obtidos. Elaborou-se um trabalho de campo, que possibilita à análise da eficiência energética no uso de motores elétricos em uma fábrica de papel e cosméticos. A partir de medidas dos parâmetros elétricos como: corrente e tensão, mais os dados de catálogos do fabricante, chegaram-se aos valores de rendimento, fator de potência e fator de utilização, para diversas condições de carga dos motores. Caso o fator de utilização seja inferior a 75%, um estudo comparativo permitirá as decisões de substituição dos motores super dimensionados. Os dados são usados para as seguintes análises: qual a possível conservação de energia elétrica para cada setor, se os motores fossem substituídos por unidades de alto rendimento?; qual a viabilidade de cada setor realizar as trocas imediatas por motores de alto rendimento?; qual à economia de energia elétrica por setores em (R$/dia), utilizando motores de alto rendimento?; em quanto tempo obteríamos o retorno desse investimento? Alguns recursos de informática foram utilizados nos cálculos realizados. Os resultados indicam que o potencial de conservação de energia elétrica em motores deve ser melhor explorado e de forma mais consciente.

Na atualidade a eficiência energética é um dos assuntos mais citados nas indústrias, pois as empresas que investem em projetos de eficiência energética conseguem economizar recursos, ganhar competitividade e ajudar a amenizar a pressão sobre o aumento da oferta de energia. Postergar parte do investimento no aumento da oferta de energia permite ao governo e ao empresário liberarem recursos para outras prioridades, sem perda de qualidade, segurança no abastecimento e com ganhos sociais e ambientais. Este estudo apresenta critérios de aplicação da metodologia da eficiência energética em uma indústria siderúrgica onde são avaliadas três áreas dentro desta usina, tais como sistemas motrizes, sistemas térmicos e sistemas de iluminação, onde pode-se obter ganhos significativos implementando a metodologia da eficiência energética.

Streszczenie:

Les moteurs électriques sont responsables de 67% de la consommation d’électricité dans l’industrie. Remplacer les moteurs installés par des entrainements plus efficients requiert de statuer sur leur adéquation avec les charges qu’ils entrainent. Une contrainte forte est de les analyser « on-line » et sans mesures intrusives ni consignations des installations.Cette thèse répond à un triple objectif. Premièrement, un dispositif de diagnostic « non-invasif » facilement intégrable en milieu industriel a été développé avec quatre méthodes d’évaluation du niveau de charge des moteurs asynchrones directement connectés au réseau. Deux de ces méthodes, existantes et basées sur la mesure du courant et du flux magnétique de dispersion, font l’objet d’améliorations significatives qui les portent à un niveau TRL7. Les deux autres méthodes exploitent la mesure seule du flux de dispersion. Leur applicabilité est vérifiée pour une alimentation par un système de tensions, équilibré ou non, avec des variations permanentes ou aléatoires. Une étude plus exploratoire montre que l’estimation non-invasive du courant absorbé par les machines asynchrones alimentées par convertisseurs électroniques est possible par exploitation du flux rayonné. Deuxièmement, le dispositif de diagnostic énergétique et des algorithmes de recherche de motorisation adaptée à un cycle de fonctionnement défini ont été appliqués à des exemples concrets d’optimisation énergétique sur un site industriel très énergivore, une aluminerie. Troisièmement, cette étude propose une réflexion sur la gestion d’un parc moteurs et, notamment, sur l'analyse des performances des moteurs neufs comparés à ceux ayant subi un rebobinage
In the industry, electrical motors are responsible for 67% of electricity consumption. Replacing installed motors by more efficient ones requires the knowledge of their suitability with the loads that they drive. Analyzing the load variations without intrusive measurements or installations consignments is a strong constraint.That is why this thesis has a threefold purpose. Firstly, a “noninvasive” diagnostic device has been developed with four methods for evaluating the load of grid-connected induction motors. Two of these methods, based on the measurement of the current and the magnetic stray flux, have been significantly improved up to TRL7. The two other methods exploit only the measurement of the stray flux. Their applicability is checked for balanced and unbalanced supply voltage systems with permanent or random variations. A more exploratory study shows that the noninvasive estimation of the current for inverter-fed induction machines is possible using the radiated external flux. Secondly, the energy diagnosis device and search algorithms adapted to an operating cycle motorization have been applied to practical examples of energy optimization in an electro-intensive industrial plant, an aluminum smelter. Thirdly, a reflection on the management of a motor fleet is proposed, in particular, on the performance analysis between new motors and rewounded ones

Energy efficiency and renewable energy use are two main priorities leading to industrial sustainability nowadays according to European Steel Technology Platform (ESTP). Modernization efforts can be done by industries to improve energy consumptions of the production lines. These days, steel making industrial applications are energy and emission intensive. It was estimated that over the past years, energy consumption and corresponding CO2 generation has increased steadily reaching approximately 338.15 parts per million in august 2010 [1]. These kinds of facts and statistics have introduced a lot of room for improvement in energy efficiency for industrial applications through modernization and use of renewable energy sources such as solar Photovoltaic Systems (PV).The purpose of this thesis work is to make a preliminary design and simulation of the solar photovoltaic system which would attempt to cover the energy demand of the initial part of the pickling line hydraulic system at the SSAB steel plant. For this purpose, the energy consumptions of this hydraulic system would be studied and evaluated and a general analysis of the hydraulic and control components performance would be done which would yield a proper set of guidelines contributing towards future energy savings. The results of the energy efficiency analysis showed that the initial part of the pickling line hydraulic system worked with a low efficiency of 3.3%. Results of general analysis showed that hydraulic accumulators of 650 liter size should be used by the initial part pickling line system in combination with a one pump delivery of 100 l/min. Based on this, one PV system can deliver energy to an AC motor-pump set covering 17.6% of total energy and another PV system can supply a DC hydraulic pump substituting 26.7% of the demand. The first system used 290 m2 area of the roof and was sized as 40 kWp, the second used 109 m2 and was sized as 15.2 kWp. It was concluded that the reason for the low efficiency was the oversized design of the system. Incremental modernization efforts could help to improve the hydraulic system energy efficiency and make the design of the solar photovoltaic system realistically possible. Two types of PV systems where analyzed in the thesis work. A method was found calculating the load simulation sequence based on the energy efficiency studies to help in the PV system simulations. Hydraulic accumulators integrated into the pickling line worked as energy storage when being charged by the PV system as well.

A la fin du 19ème siècle, le réseau électrique prend forme et l’électricité comme source d’énergie commence à être utilisée, pour l’éclairage et les communications principalement, et dans une moindre mesure comme force motrice. Dans cette thèse, nous analysons les conditions sociologiques de calculs de rendement des premiers moteurs électriques, les méthodes théoriques et expérimentales utilisées par les premiers ingénieurs électriciens pour démontrer que les moteurs électriques pouvaient remplacer efficacement d’autres types de moteurs, vivants ou pas, alors disponibles dans l’industrie. Les machines électriques étaient également comparées entre elles, et celles qui permettaient d’obtenir un système de transport et de distribution avec le rendement le plus élevé étaient en théorie retenue par l’industrie. Dans la pratique, d’autres critères entraient en jeu, les électriciens défendant un certain type de machines ou de systèmes de transport devant aussi convaincre la communauté scientifique et l’industrie intéressées par leur découverte. S’appuyant sur l’analyse de ce contexte faite à partir de textes de revues techniques et de documents d’archives ainsi que de travaux de sociologie et d’histoire, cette thèse vise à mieux comprendre l’essor de ce type particulier de machines, symboles de la quête d’une certaine efficacité

In practice, other criteria came into play, as electricians defending a certain type of machinery or transport systems also had to convince the scientific community and industry interested in their discovery. Based on an analysis of this context made from texts from technical journals and archival documents, as well as from works of sociology and history, this thesis aims to better understand the development of this particular type of machines, symbols of the quest for a certain efficiency

This work focused on Impacts of power quality on an online induction motor in a real time basis. The work involves creating variable conditions in the input power supply and analyzing its impacts on motor performance specially efficiency. Input power supply is modulated in two aspects, first one is voltage fluctuation and second one is voltage unbalance. For the conduct of test a 10 HP induction motor is selected which is run under test condition for half an hour. During test input supply voltage is varied on both sides of the rated voltage of the motor with the help of servo voltage stabilizer. In process voltage unbalance condition was also implied on the motor by varying the voltage across three phases. All measurement parameters during test are recorded with the help of Fluke 438 II Power quality and motor analyzer. The test results have indicated that motor efficiency deteriorates whenever there is a deviation from rated voltage of the motor. It also shown the same trend when voltage unbalance is increased. Thus, it implies that power quality plays a major role in the performance of the motor.

Streszczenie:

The purpose of this dissertation is to study the effectiveness of public policies in generating fuel savings and emissions reductions. I focus on applying various empirical methods to analyze consumer responses to policy changes on both extensive and intensive margins. This dissertation consists of two chapters.

In the first chapter, I compare the effectiveness of fuel taxes and product taxes on reducing gasoline consumption of new car buyers. I employ a unified data source for vehicle choice and subsequent vehicle use to estimate a random effects logit demand model that explicitly accounts for vehicle use heterogeneity. My demand estimation suggests that new car buyers fully value the fuel-saving benefits from improved vehicle fuel efficiency when they initially purchase their cars. My policy simulations indicate that high-mileage drivers are more responsive to a change in fuel taxes than to a change in product taxes, even as low-mileage drivers are more responsive to product taxes. By capturing such heterogeneous consumer response to policies, I show that a counterfactual increase of the fuel tax is more effective than a revenue-equivalent product tax in reducing the total gasoline consumption of new car buyers. Further, when accounting for its effects on consumer response on both extensive and intensive margins, a change in fuel taxes has a clear advantage over a change in product taxes in reducing the consumption of gasoline even when the magnitude of tax increase is small. More importantly, a model not accounting for vehicle use heterogeneity understates the fuel saving effects of both policies and misleads us about the relative effectiveness when comparing different policies.

The second chapter explores how changes in the marginal cost of driving affect consumers decisions about passenger vehicle utilization, as measured by average daily miles traveled per vehicle. This intensive margin of consumer response has important implications for the effectiveness of usage-based policies, such as the fuel tax and the mileage tax, that designed to address externalities of driving. I estimate the elasticity of driving with respect to fuel cost per mile using a large panel data that covers 351 towns and cities in Massachusetts over 24 quarters. While most researchers in this literature apply fixed effects estimators to examine the elasticity of driving, I use a factor model econometric setup to account for unobserved common factors and regional heterogeneity. Residual diagnostics confirm that the factor model setup does a better job of removing the cross-section dependence than fixed effects estimators do. Given low consumer responsiveness to changes in the marginal cost of driving engendered by current usage-based policies, rights-based approaches like congestion charges might be better alternatives to influence vehicle utilization and vehicle ownership.

Porter’s “diamond model” (also known as the “theory of national competitive advantage of industries”) points out "demand conditions,” "factor conditions,” “strategy, structure & rivalry,” “related supporting industries,” and “government” are five major dimensions (also known as “five forces”) that affect a company’s ability to compete in the international arena, especially for certain countries. There are various factors and/or criteria under each of the five dimensions. Based on the diamond model, this study aims to explore the key dimension and criteria that affect the industrial development of high-efficient motors in Taiwan. In the study, a total of fifteen criteria were selected within the above five dimensions. A questionnaire was designed and used for collecting opinions from a group of professionals and scholars. The data were analyzed by the method of Fuzzy DEMATEL (Fuzzy Decision Making Trial and Evaluation Laboratory), and the key dimension and criteria having significant impacts on the industry were disclosed. Afterwards, DANP (Decision Making Trial and Evaluation Laboratory Based on Analytic Network Process) was employed, and priorities of those criteria were found. The major conclusion of this study is that “demand conditions” is the most important dimension among Porter’s five dimensions. As for those key factors/criteria, the most two important criteria are (1) The industry has to improve the performance of motor power system rather than motor itself; (2) The multidisciplinary integration and cooperation among companies are important for future development of the industry.

Streszczenie:

In the absence of hard data, the engineering world tends to be overly conservative in estimating benefits of change. The hypothesis herein discussed is that with hard data, the economics of motor repair/replace decisions could change significantly. If true, this could appreciably boost the efficiency of the industrial motor population by affecting the penetration of high-efficiency motors, such as NEMA Premiums. The energy savings from motor replacement depend on the difference between the efficiency of the new motor and the old motor. There has been a great deal of work investigating new motor efficiency and very little work investigating the actual running efficiency of older motors in the field. Motors that have operated for years experiencing failures and repairs may operate below their original nameplate or assumed efficiency. This study is a preliminary investigation of the efficiency of motors in industrial settings with the purpose of updating currently available motor analysis software tools to more accurately reflect the economic benefits of utilizing high-efficiency industrial induction motors.
