Abstract:
The article presents a new method of the optimal design of the electrical rotating machine based on genetic algorithm. The mathematical description of the proposed algorithm is developed, and the optimal design of the high-speed electrical rotating machine by proposed method is performed. A new method for optimal design allows obtaining a new electrical rotating machine which mass is lower than mass of the initial electrical rotating machine by two times; the value of the rotor active length is lower by 2.37 times and the current density is higher by 1.7 times in comparison with the initial electrical rotating machine. The losses are increased by only 25 percent (power, rotation frequency and materials of both electrical rotating machine are the same).

Abstract:
Electrical machines are prone to faults and failures and demand incessant monitoring for their confined and reliable operations. A failure in electrical machines may cause unexpected interruptions and require a timely inspection of abnormal conditions in rotating electric machines. This article aims to summarize an up-to-date overview of all types of bearing faults diagnostic techniques by subdividing them into different categories. Different fault detection and diagnosis (FDD) techniques are discussed briefly for prognosis of numerous bearing faults that frequently occur in rotating machines. Conventional approaches, statistical approaches, and artificial intelligence-based architectures such as machine learning and deep learning are discussed summarily for the diagnosis of bearing faults that frequently arise in revolving electrical machines. The most advanced trends for diagnoses of frequent bearing faults based on intelligence and novel applications are reviewed. Future research directions that are helpful to enhance the performance of conventional, statistical, and artificial intelligence (machine learning, deep learning) and novel approaches are well addressed and provide hints for future work.

Abstract:
This thesis seeks to advance the design tools for electrical generators. It aims to undertake an electrical generator’s design, using the Finite Element method within a defined time frame. The thesis looks at the history of generator design systems and outlines the parameters a designer must predict. These parameters are then duly calculated using various finite element methods. The thesis introduces a Pseudo Rotating Superposition system, which allows large quantities of data to be found from single static finite element simulations. Initially the system is used to predict machine saturation curves, and it is later expanded to predict the transient performance of generators. The full load performance of generators is found using a novel multivariable clustered optimisation routine. An extension using a rotating finite element solver, with pseudo rotating superposition, is then demonstrated. This creates a method which allows voltage harmonics to be quickly, accurately and validly predicted. Finally a study of iron loss is undertaken and using the above method it is shown that iron loss can be validly calculated using the quicker Radial/Tangential reference frame, rather than a slower Major/Minor frame. A collection of 48 manufactured machines are used throughout as a test group for the created methods. Results from design calculations are compared to both factory test results and to the predictions from an existing customised in house design software tool. The methods within this thesis are shown to be over 35% more accurate in the majority of cases. The whole suite of methods created can automatically calculate results for any given machine in less than 1 hour. The computer macros described in this thesis and the comparison with existing design methods and test were all made by the Author.

Abstract:
Thermal analysis is an important topic that can affect the electrical machine performance, reliability, lifetime and efficiency. In order to predict the electrical machine thermal performance accurately, thermal analysis of electrical machines must include fluid flow modelling. One of the technologies which may be used to estimate the flow distribution and pressure losses in throughflow ventilated machines is flow network analysis, but suitable correlations that can be used to estimate the pressure losses in rotor ducts due to fluid shock is not available. The aim of this work is to investigate how the rotation affects the pressure losses in rotor ducts by performing a dimensional analysis. Apart from the additional friction loss due to the effects of rotation, other rotational pressure losses that appear in a rotor-stator system are: duct entrance loss due to fluid shock and combining flow loss at the exit of the rotor-stator gap. These losses are analysed using computational fluid dynamics (CFD) methods. The CFD simulations use the Reynolds-averaged Navier Stokes (RANS) approach. An experimental test rig is built to validate the CFD findings. The investigation showed that the CFD results are consistent with the experimental results and the rotational pressure losses correlate well with the rotation ratio (a dimensionless parameter). It shows that the rotational pressure loss generally increases with the increase in the rotation ratio. At certain operating conditions, the rotational pressure loss can contribute over 50 % of the total system loss. The investigation leads to an original set of correlations for the pressure losses in air ducts in the rotor due to fluid shock which are more suitable to be applied to fluid flow modelling of throughflow ventilated machines. Such correlations provide a significant contribution to the field of thermal modelling of electrical machines. They are incorporated into the air flow modelling tool that has been programmed in Portunus by the present author. The modelling tool can be integrated with the existing thermal modelling method, lumped-parameter thermal network (LPTN) to form a complete analytical thermal-fluid modelling method.

Abstract:
Transient simulation programs are used extensively for modeling and simulation of various electrical power and energy systems that include rotating alternating current machines as generators and motors. In simulation programs, traditionally, the machine models are expressed in qd-coordinates (rotational reference frame) and transformed variables, and the power networks are modeled in abc-phase coordinates (physical variables), which represents an interfacing problem. It has been shown in the literature that the method of interfacing machine models and the electric network models plays an important role in numerical accuracy and computational performance of the overall simulation. This research considers the state-variable-based simulation programs and proposes a unified constant-parameter decoupled RL-branch circuit in abc-phase coordinates (with optional zero-sequence). The proposed circuits are based on voltage-behind-reactance (VBR) formulation and can be used for interfacing both induction and synchronous machine models. The new models achieve a direct and explicit interface with arbitrary external electrical networks, which results in many computational advantages. Extensive computer studies are presented to verify the proposed models and to demonstrate their implementation in several commonly-used simulation programs. The new models are shown to offer significant improvements in accuracy and numerical efficiency over the existing state-of-the-art models due to their direct interface. It is further envisioned that the proposed models will receive a wide acceptance in research community and simulation software industry, and may enable the next generation of power systems simulation tools.

Abstract:
Lo scopo di questa tesi è presentare alcuni metodi efficienti (dal punto di vista computazionale) per il calcolo degli effetti dovuti alle correnti parassite (eddy currents) in macchine elettriche rotanti in media tensione. Due applicazioni in particolare sono state considerate nel dettaglio. Inizialmente viene analizzato il fenomeno delle correnti parassite indotte nell'albero di motori asincroni a due poli e il conseguente effetto sulle prestazioni della macchina, focalizzandosi in particolare sul fattore di potenza. La seconda parte della tesi concentra la sua attenzione sullo studio dell'avviamento da rete di motori sincroni con rotore massiccio. Per ciascuna applicazione vengono introdotte alcune procedure di calcolo, facenti uso di opportuni modelli numerici basati sul metodo degli elementi finiti, per mezzo delle quali vengono adeguatamente calcolati i parametri dei circuiti equivalenti di macchina, tenendo conto degli effetti legati alle correnti parassite. I modelli numerici sono opportunamente definiti, in modo tale da ridurre al massimo la complessità delle geometrie e il conseguente onere computazionale. I risultati delle procedure innovative qui proposte sono confrontati con i dati provenienti da prove sperimentali sulle macchine oggetto di studio e con analoghi risultati di calcolo dedotti tramite le procedure comunemente utilizzate. Il confronto fra questi dati ha dimostrato che gli approcci di calcolo introdotti in questa tesi permettono di ottenere risultati con un elevato livello di accuratezza e una netta riduzione dell'onere computazionale.
The efficient computation of eddy-current effects in medium voltage electric machines is discussed in this dissertation. Two particular cases are considered. Firstly, the effects of shaft eddy-currents on two-pole induction motor performance is addressed, with special focus on the power factor. In the second part of the thesis the start-up calculation of a large synchronous motor with solid rotor is analyzed. For each application a special calculation procedure is introduced. These procedures adopt a set of suitable finite-element models to properly compute the machine equivalent circuit parameters that are mainly influenced by eddy-current-related phenomena. By suitably choosing finite-element models boundary conditions and excitations their geometry is simplified to the maximum possible extent, in order to reduce the computational burden. The results of the new calculation methods are compared with experimental data and with analogous results obtained from commonly-adopted calculation procedures. The comparison proves that the proposed approaches can lead to high accuracy levels with very remarkable computational savings.

Abstract:
The interest for Permanent Magnet (PM) synchronous machines has increased in the recent years. This is mainly due to important developments in the field of the electrical machine design, control systems and PM technology. These factors enable the possibility of designing electrical machines with a high torque density, power density, efficiency, low cost with wide degrees of freedom. Such requirements are highly sought in the automotive field, especially following the increasingly stringent energy efficiency and air pollution emissions policies. These conditions are pushing forward the transition from the conventional internal combustion engine mobility systems to the hybrid electric and full electric vehicles for the mass market production. Moreover, further requirements, especially in high demanding traction and auxiliary machines, such as Electric Power Steering (EPS) motors, are nowadays getting more and more important. Flux weakening performance, torque quality (cogging torque and torque ripple), demagnetization, acoustic performance and robustness of the designs has to be taken into account, together with stringent dimensional, electrical and thermal constraints typical for compact integrated automotive electrical drives. Due to recent sky-rocketing price, instability, critical availability of Rare Earth (RE) metals and the related environmental issue for their sourcing, Heavy (HR) RE free, RE-free and even PM free machines are hunted for in the automotive market. The novel PM motor topologies meet such a „market pull“. The main research subject of this PhD is the development of novel analysis and design procedures of PM synchronous machines for automotive applications. The latter range from low torque / power auxiliary systems, i.e. EPS machines, to high torque / high power applications, such as traction machines. It provides a comprehensive evaluation of various synchronous machine topologies. Particular attention is devoted to the study of HRE-free solutions and the development of Finite Element Analysis (FEA) and analytical procedures for the optimization of the motor designs. As mentioned above, these methodologies take into account several electromechanical constraints and various performance targets. As regards the traction machines, the investigation is focused to the permanent magnet assisted reluctance (PMASR) topology. The interest around the PMASR motors has grown in the last years especially as consequence of the price crisis of rare earth magnets. In fact these machines represent a potential low cost replacement of conventional PM machines due to several technical advantages, such as wide speed range, competitive torque density and efficiency, high overload capability and robust structure. On the other had, the most important drawback is represented by the high torque ripple. In the area of the electric power steering motors, several topologies, both with isotropic anisotropic rotor structures and equipped with fractional slot concentrated windings, are evaluated. Some novel motor designs, which employ the reluctance and flux concentration principle, are introduced, optimized by means of FEA procedures and experimentally validated in detail, including the acoustic and PM performance. Further considerations are derived on the robustness of the solutions against the manufacturing imperfections. Comparing to the isotropic topologies, these innovative motor configurations show higher torque density, extended speed range, optimal torque quality and acoustic performance, ensuring lower active cost and structural simplicity. Therefore, they represent attractive candidates for high performance automotive applications.
Negli ultimi anni l'interesse nel settore delle macchine sincrone a magneti permanenti ha riscontrato una notevole crescita. Questo e' stato determinato principalmente da importanti sviluppi nel campo della progettazione delle macchine elettriche, nei sistemi di controllo e nelle tecnologie dei magneti permanenti. Questi fattori hanno reso possibile la progettazione di macchine elettriche con elevata densita' di coppia, densita' di potenza, rendimento, basso costo unitamente ad ampi gradi di liberta' nella geometria e struttura della macchina. Tali requisiti sono fortemente ricercati nel campo automotive, soprattutto a seguito dell'introduzione di sempre piu' stringenti normative sull'efficienza energetica e sulle emissioni atmosferiche inquinanti. Questi aspetti hanno accelerato la transizione da sistemi di mobilita' tradizionali con motori a combustione interna a veicoli ibridi-elettrici e puramente elettrici, nella produzione industriale di massa. Inoltre, ulteriori requisiti, specialmente in macchine da trazione ed ausiliarie ad alte prestazioni, quali ad es. motori per servosterzo elettrico, stanno attualmente diventando sempre piu' importanti. Prestazioni in deflussaggio, qualita' della coppia (coppia di impuntamento ed oscillazione della coppia), smagnetizzazione, prestazioni acustiche e robustezza delle configurazioni devono essere tenute in conto, insieme a stringenti vincoli dimensionali, elettrici e termici tipici di azionamenti elettrici compatti ed integrati. A causa dell'incremento significativo ed instabilita' dei prezzi delle terre rare, della criticita' dei loro approvvigionamenti ed i relativi impatti ambientali, soluzioni prive di terre rare pesanti, senza terre rare od addirittura senza magneti permanenti, sono fortemente ricercate nel settore automotive. La principale tematica di ricerca di questo dottorato riguarda lo sviluppo di innovative procedure di analisi e sintesi di macchine sincrone a magneti permanenti per applicazioni automotive. Queste ultime spaziano da sistemi ausiliari a bassa coppia / bassa potenza, nella fattispecie motori per servosterzo elettrico, fino a applicazioni at alta coppia / alta potenza, quali ad es. motori da trazione. Questo lavoro fornisce una valutazione complessiva di differenti tipologie di macchine. Particolare attenzione e' dedicata allo studio di soluzioni con magneti permanenti privi di terre rare pesanti ed allo sviluppo di procedure di ottimizzazione ad elementi finiti ed analitiche della geometria del motore. Come menzionato precedentemente, tali metodologie tengono in considerazione numerosi vincoli elettromeccanici e differenti obiettivi. Per quanto riguarda le macchine da trazione, la ricerca si e' focalizzata sulla topologia di motori a riluttanza assistiti da magneti permanenti. L‘interesse attorno a tali macchine e' cresciuto negli ultimi anni soprattutto a seguito della crisi dei prezzi dei magneti permanenti a terre rare. Infatti, tali macchine rappresentano una soluzione alternativa a basso costo rispetto a motori a magneti permanenti tradizionali a causa di importanti vantaggi tecnici quali ad es. un ampio regime di velocita', competitivi valori di densita' di coppia ed efficienza, elevata capacita' di sovraccarico ed una robustezza della struttura. D'altra parte, uno dei principali svantaggi e' rappresentato dall'elevata oscillazione della coppia. Nel campo dei motori per servosterzo elettrico, differenti topologie, sia dotate di rotore isotropo che anisotropo ed equipaggiate con avvolgimenti concentrati, sono state valutate. Alcune nuove configurazioni, che sfruttano il principio della riluttanza e della concentrazione di flusso, sono introdotte, ottimizzate per mezzo di procedure ad elementi finiti ed infine validate per mezzo di misure sperimentali, includendo valutazioni delle prestazioni acustiche e quelle dei magneti permanenti. Ulteriori considerazioni sono tratte per quanto concerne la robustezza delle soluzioni nei confronti delle imperfezioni costruttive. Rispetto alle macchine isotrope, tali configurazioni sviluppano una densita' di coppia piu' alta, esibiscono un piu' ampio intervallo di velocita', maggiore rendimento raggiungendo un qualita' della coppia e prestazioni acustiche competitive ad un costo inferiore e con una buona semplicita' costruttiva. Esse si dimostrano, pertanto, dei candidati ottimali per applicazioni automotive ad alte prestazioni.

Abstract:
The grid code, FIKS, from the Norwegian transmission system operator (TSO), Statnett, states that synchronous generators > 25MVA, must have a static excitation system. However, an improved brushless excitation system is in operation on some commercial power plants (36MVA, 93.75rpm & 52MVA, 166.67rpm) with grid-assisting performance beyond the conventional static system. The convenional diode bridge is replaced with a remote-controlled thyristor bridge on the shaft. If wireless communication is not allowed, a control signal through brushes should be employed instead. The thesis explores the expected new era for large brushless hydrogenerators. The proposed brushless system have benefits of reduced regular maintenance due to elimination of brushes and reduced unscheduled maintenance due to redundancy; causing a redused cost-of-energy. A six-phase exciter design with a hybrid-mode thyristor bridge interface leads to improved fault-tolerance, better controllability, minimized torque pulsations and reduced armature currents of the exciter. Excitation boosting (EB) capability is included in the brushless system without additional components or circuitry, contrary to the static excitation system. The brushless excitation system is made insensitive to voltage dips in the interconnected grid, causing improved fault ride-through (FRT) capability and power system stabilizer (PSS) actions.

Abstract:
Les matériaux ferromagnétiques doux, souvent employés sous la forme de tôles laminées fines, sont utilisés dans les stators et rotors des machines électriques tournantes. Le rendement de ces machines est réduit par des pertes dites "pertes fer", dues aux mécanismes d'aimantation et aux courants induits. La nature du matériau reflétée par sa structure magnétique couplée à la géométrie, à l'anisotropie et à la texture de la surface sont autant de facteurs qui influent sur les performances électromagnétiques finales. Ces travaux de thèse ont donc pour objectif de proposer des matériaux magnétiques sur mesure par texturisation laser sélective de surface pour des dispositifs électromagnétiques tels que les machines électriques tournantes. L'applicabilité d'un tel procédé au niveau industriel pour des matériaux à grains orientés ou à grains non orientés dans les machines électriques nécessite de contrôler davantage la technologie et les spécifications du procédé dans le but d'optimiser les propriétés électromagnétiques. En effet, l'impact déterministe de cette technique sur la structure magnétique d'un matériau et ses performances observables (perméabilité magnétique et pertes fer) reste incomplètement appréhendé, modélisé et connu. Les conditions d'industrialisation doivent être analysée et optimisée vis-à-vis des contraintes techniques et économiques. On cherche donc ici à étudier l'impact d'une texturisation de surface par laser pulsé sur la structure magnétique en surface et en volume d'un matériau pour pouvoir les contrôler. L'adaptation des procédés laser avec augmentation de la vitesse de traitement est étudiée théoriquement, puis engagée et vérifiée expérimentalement pour correspondre aux ambitions d'industrialisation. Ainsi, ce travail effectué en très grande proximité avec le projet européen H2020 ESSIAL permettra de proposer différents traitements de surface adaptés aux machines tournantes pour ajuster certaines propriétés magnétiques, de façon théorique et expérimentale
Soft ferromagnetic materials, which are often used in the form of laminated sheets, compose rotating electrical machines' stators and rotors. The efficiency of those machines is reduced by losses called "iron losses", induced by magnetization mechanisms and eddy currents. Those magnetization reversal mechanisms can only be explained with the magnetic structure coupled to the material geometry, anisotropy and surface texture, which are also deterministic factors for the final electromagnetic performances. Then, present work aims at proposing tailor-made soft ferromagnetic materials by means of selective laser texturizing for electromagnetic devices such as rotating electrical machines. To apply such a process at an industrial level for grain-oriented and non-grain-oriented materials in electrical machines, it is necessary to better control the associated technology and specify the process in order to optimize electromagnetic properties. Indeed, the deterministic impact of this technic on a material's magnetic structure and its performances (magnetic permeability and iron losses) remains partially modelled and understood. The integration of such solution at the industrial scale must be analyzed and optimized regarding technical and economical constraints. In this work, the study of the impact of laser surface texturizing on magnetic structure (regarding surface and volume) of a material with the aim to control it is performed. Future industrialization requires to adapt the pulsed laser processes at a higher speed which has been theoretically studied, initiated and experimentally verified. To finish, present work performed in parallel with the H2020 European project ESSIAL will allow to propose different surface treatments adapted to rotating machines to adjust some quantifiable electromagnetic properties with the help of both experimental and theoretical tools

Abstract:
The increase of greenhouse gas emission is commonly accepted to largely contribute to global warming, in part due to the massive use of non-renewable fossil energy sources. It is a reason why recently, beside other industrial sectors, electric mobility has been considered as the next generation for transportation systems. But the electrification of a vehicle introduces new challenges in its design since it involves different domains of expertise than the ones from Internal Combustion Engine (ICE) vehicles. In particular, Noise, Vibration and Harshness (NVH) comfort is significantly affected by powertrain changes, i.e. from ICE to electric machine. High and unpleasant acoustic noise from resonances may occur but can be addressed numerically to support decision making processes early enough in the design stages. The accurate prediction of its radiated acoustic noise then requires a thorough multi-physical understanding, from the system-level (electric machine) to the component-level (stator and rotor cores).First from a system-level point of view, two multi-physical modeling frameworks that use different model simplifications were implemented. By comparing simulated results to experimental measurements at each physical step of the modeling flow (electromagnetic, vibration, acoustic), it was shown that both models are accurate enough for pre-designing phases. It was also shown that considering only the stator core to contribute to the vibro-acoustic behavior of electric machines is a valid assumption.Second from a component-level point of view, the rotor and the stator core were investigated. The rotor influence on the complete machine structural dynamics was assessed. Beside the validated effects of different rotor topologies on the radiated noise, an analytical model was successfully developed to explain the occurrence of a particular vibration mode; whose explanation was still not offered in literature. In parallel, the stator core was studied, essentially because it is composed of hundreds of thin laminations stacked together which introduce difficulties in understanding its structural behavior. The effects of the laminations on the structural behavior of the stator core were studied numerically and experimentally as well. Two modeling guidelines were thus provided depending on the mode shape of interest and the computational resources available. The experimental studies comforted these two modeling approaches, and also permitted to highlight the importance of looking at the damping properties. Therefore it was shown that different lamination stacking techniques could affect significantly this damping.Finally the influence of the stacking technique (gluing, welding) on the structural behavior of the laminated compound motivated the implementation of an alternative solution to the mitigation of resonance phenomenon responsible for large acoustic noise. By using a skewed distribution of welding or glue lines, the technique aims at forcing laminations to vibrate with different phases which generates friction between them. The induced damping increases and then depends on the introduced asymmetry and on the mode shape considered. This innovative technique was validated experimentally and showed up to 7 times higher structural damping and 10 dB reduction in structural transfer function amplitudes.
