Book excerpt: Ce mémoire présente l'étude d'une alimentation originale alternative pour moteur à reluctance variable a double saillance. Dans le premier chapitre, un rappel des principes de fonctionnement et d'alimentation des moteurs à reluctance variable à double saillance est rappelé. Différents types d'alimentations faisant appel a des convertisseurs a commutation douce et des ondes sinusoïdales sont présentées. A partir de la constatation que le sens du courant n'est pas impose par principe, un convertisseur rustique est propose. Ce convertisseur direct constitue d'un triac par phase du moteur est utilise pour injecter du courant dans les phases du moteur pendant la croissance de l'inductance. Une commande avec limitation de courant n'est pas nécessaire avec ce type d'alimentation. Les résultats obtenus avec cette alimentation sont étudiés dans le chapitre 3. Le couple moyen en fonction de la vitesse est explicite, ainsi que l'évolution des pertes dans le moteur. Deux modes de fonctionnement en fonction du rapport de la fréquence du réseau a la fréquence électrique du moteur sont distingues. Enfin, le courant absorbe par le moteur est étudié et une méthode de compensation partielle du facteur de puissance est proposée. Dans le chapitre 4, une amélioration permettant de réduire l'ondulation du courant absorbe est étudiée.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: La machine à réluctance variable à double saillance (MRV-DS) a largement été utilisée dans le domaine du positionnement incrémental. Avec les derniers progrès en électronique de puissance et de commande, le domaine d'utilisation de la MRV-DS tend à se diversifier avec des applications en fonctionnement synchrone à très grande vitesses. Quel que soit le fonctionnement envisagé, pas-à-pas ou synchrone, il est nécessaire d'élaborer un modèle de la machine pour pouvoir prédéterminer ses performances. Le mémoire de thèse est consacré à la modélisation et à l' étude de la MRV-DS dans son environnement de commande. Un modèle analytique classique est d'abord utilisé pour étudier le fonctionnement du moteur et dégager les aspects essentiels de son fonctionnement électromécanique. Il est également utilisé pour étudier le système commandé.
Book Synopsis Control of Non-conventional Synchronous Motors by : Jean-Paul Louis
Download or read book Control of Non-conventional Synchronous Motors written by Jean-Paul Louis and published by John Wiley & Sons. This book was released on 2013-02-04 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors, synchronous and switched reluctance motors, stepping motors and piezoelectric motors. This book presents efficient controls to improve the use of these non-conventional motors. Contents 1. Self-controlled Synchronous Motor: Principles of Function and Simplified Control Model, Francis Labrique and François Baudart. 2. Self-controlled Synchronous Motor: Dynamic Model Including the Behavior of Damper Windings and Commutation Overlap, Ernest Matagne. 3.

This book was released on 1996 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA STRUCTURE DE LA MACHINE A RELUCTANCE VARIABLE A DOUBLE SAILLANCE EST CONNUE COMME LA STRUCTURE LA PLUS ECONOMIQUE. CEPENDANT, LES CARACTERISTIQUES FORTEMENT NON LINEAIRES DE LA MACHINE RENDENT SON PILOTAGE DELICAT. PAR CONSEQUENT, LA MISE AU POINT D'UNE COMMANDE PERFORMANTE NE PEUT SE FAIRE AU MOYEN DES TECHNIQUES CLASSIQUES DE L'AUTOMATIQUE LINEAIRE. DANS CE MEMOIRE NOUS AVONS DEVELOPPE UNE METHODOLOGIE POUR COMMANDER LE COURANT ET LA VITESSE DE LA MRV EN REGIME LINEAIRE ET SATURE, A TRAVERS DEUX APPROCHES. LA PREMIERE CONSISTE A TROUVER LA FORME DE LA CONSIGNE DE COUPLE DE PHASE QUI PERMET D'AVOIR UNE CONSIGNE DE COUPLE POLYPHASE CONSTANT. LA DEUXIEME APPROCHE PERMET DE COMPENSER LA FORCE CONTRE-ELECTROMOTRICE DE LA MACHINE A HAUTES VITESSES. L'INTERET DE CES DEUX APPROCHES A ETE MIS EN EVIDENCE A TRAVERS UNE ETUDE COMPARATIVE DE PLUSIEURS METHODES DE COMMANDE NON LINEAIRES (MODULATION NATURELLE, HYSTERESIS, LOGIQUE FLOUE ET MODE DE GLISSEMENT) APPLIQUEES A LA COMMANDE DU COURANT ET DE LA VITESSE

This book was released on 1995 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous étudions un moteur à réluctance variable à double saillance avec quatre dents statoriques et deux dents rotoriques dont les deux phases sont câblées en demi-pont asymétrique. Son nombre de phase étant faible, le démarrage pose problème et nécessite l'élaboration d'une loi de commande complexe pour compenser la simplicité du capteur de position constitue d'une roue dentée et d'une fourche optique. Un modèle éléments finis couple électronique-magnétique-cinématique est alors construit, validé puis utilisé pour résoudre les problèmes lies au démarrage. De plus, les cotations de la géométrie du moteur et les instants de commutation des interrupteurs doivent être déterminés pour satisfaire au mieux le problème de conception formule au moyen d'un cahier des charges. Une méthodologie est proposée pour résoudre les problèmes de conception des dispositifs électromagnétiques. Elle consiste, dans un premier temps, à exprimer le problème de conception dans un formalisme mathématique puis, dans un deuxième temps, à appliquer des méthodes d'optimisation pour le résoudre. L'outil qu'est le modèle éléments finis et la méthodologie de résolution du problème de conception sont ensuite utilisés conjointement pour l'optimisation d'un moteur à réluctance variable à double saillance.

Book Synopsis The Rediscovery of Synchronous Reluctance and Ferrite Permanent Magnet Motors by : Gianmario Pellegrino
Download or read book The Rediscovery of Synchronous Reluctance and Ferrite Permanent Magnet Motors written by Gianmario Pellegrino and published by Springer. This book was released on 2016-04-28 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an essential compendium on the analysis and design of synchronous motors for variable-speed applications. Focusing on synchronous reluctance and ferrite permanent-magnet (PM) synchronous reluctance machines, it provides a broad perspective on three-phase machines for variable speed applications, a field currently dominated by asynchronous machines and rare-earth PM synchronous machines. It also describes synchronous reluctance machines and PM machines without rare-earth materials, comparing them to state-of-the-art solutions. The book provides readers with extensive information on and finite element models of PM synchronous machines, including all relevant equations and with an emphasis on synchronous-reluctance and PM-assisted synchronous-reluctance machines. It covers ferrite-assisted machines, modeled as a subcase of PM-assistance, fractional slot combinations solutions, and a quantitative, normalized comparison of torque capability with benchmark PM machines. The book discusses a wealth of techniques for identifying machine parameters, with an emphasis on self-commissioning algorithms, and presents methods for automated machine design and optimization, including a software tool developed for this purpose. Addressing an important gap in the field of PM-less and less-PM electrical machines, it is intended as a self-contained reference guide for both graduate students and professional machine designers, and as a useful text for university courses on automated and/or optimized design of electrical machines and drives.

Available in PDF, EPUB and Kindle. Book excerpt: With Contributions by Capers Jones, Howard Rubin, David Garmus, Lawrence Putnam, and Elizabeth Clark The accurate, quantitative measurement of software quality and process performance is rapidly becoming an essential part of competition in the ever-tightening software marketplace. Software metrics provide insights into productivity and quality gains from improvements in skill, technology, and development methodology. An effective metrics program helps practitioners assemble the best team, select the optimal development methodology, and enhance the quality of a software product. In short, metrics enable software developers to pursue proven, successful strategies, and to change course when metrics point to less-than-optimum quality or productivity. Written by the world's leading authorities in the field, IT Measurement showcases state-of-the-art in software metrics and provides the practical knowledge that practitioners need in order to take full advantage of software metrics technology. The book's collected articles offer important perspectives on the role of metrics in the development process, and show how metrics directly enhance software quality and output efficiency. The book explores several vital areas, including Function Point Analysis, project estimation and management, outsourcing, statistical process control, and more. These articles range from basic theory to the sophisticated application of metrics. Specific topics covered include: The expanding role of function point metrics Work output measurement for IT work units The use of metrics for tracking Enhanced estimation with metrics Metrics in outsourcing Standardization of SLOC The application of SPC to performance management Functional metrics in B2B e-commerce project success Enlightening and pragmatic, IT Measurement will help you gain a deeper understanding of software metrics and the ability to apply concrete measures in order to objectively evaluate and more finely shape your software development program. 020174158XB02212002
