Available in PDF, EPUB and Kindle. Book excerpt: UN MODELE REPRESENTANT LES MOTEURS ASYNCHRONES TRIPHASES A SIMPLE OU DOUBLE CAGE EST PROPOSE. IL EST BASE SUR LE PRINCIPE DU SCHEMA EQUIVALENT ELARGI AFIN D'Y INCLURE LES HARMONIQUES DE TEMPS DE LA TENSION D'ALIMENTATION ET LES HARMONIQUES D'ESPACE DE LA FORCE MAGNETOMOTRICE. LA SATURATION EST PRISE EN COMPTE PAR L'INTERMEDIAIRE DE FACTEURS DE SATURATION APPLIQUES AUX DIFFERENTES REACTANCES. CES FACTEURS SONT CALCULES POUR CHAQUE POINT DE FONCTIONNEMENT, EN FONCTION DU FLUX GLOBAL DE LA MACHINE A PARTIR DE LA COURBE REELLE B(H) DU MATERIAU MAGNETIQUE. CE MODELE A FAIT L'OBJET DE VALIDATION COMPLETE SUR UN GRAND NOMBRE DE MOTEURS DE PUISSANCE ET DE POLARITE DIFFERENTE. UNE ETUDE DE L'INFLUENCE DES PARAMETRES GEOMETRIQUES ET DE BOBINAGE EST EFFECTUEE. ELLE PERMET D'OPTIMISER CERTAINS PARAMETRES TELS QUE LE NOMBRE D'ENCOCHES STATOR PAR POLE, LE RACCOURCISSEMENT DU PAS DE BOBINAGE AINSI QUE L'INCLINAISON DES BARRES ROTORIQUES

Book excerpt: CETTE ETUDE A POUR BUT DE DEVELOPPER UN OUTIL DE MODELISATION PAR ELEMENTS FINIS DE LA MACHINE ASYNCHRONE QUELQUES SOIENT SA GEOMETRIE, SES CARACTERISTIQUES PHYSIQUES ET SON REGIME DE FONCTIONNEMENT. LA METHODE DES ELEMENTS FINIS 2D APPLIQUEE A L'ELECTROMAGNETISME, CONSISTE A DECRIRE DANS UN PLAN LA GEOMETRIE DE L'OBJET A ETUDIER, A LA MAILLER, PUIS A RESOUDRE LES EQUATIONS GENERALES DE L'ELECTROMAGNETISME (MAXWELL) SUR TOUS LES NUDS DU MAILLAGE EN TENANT COMPTE DES PROPRIETES PHYSIQUES AFFECTEES SUR LES ELEMENTS. LE MOTEUR ASYNCHRONE EST UN OBJET ELECTROMAGNETIQUE TRES COMPLEXE ENTRAINANT L'UTILISATION DE LA MAGNETODYNAMIQUE COMPLEXE POUR TENIR COMPTE DE L'EFFET DE PEAU DANS LES BARRES DE LA CAGE ROTORIQUE. L'ALGORITHME DE NEWTON-RAPHSON EST UTILISE POUR RESOUDRE LE PROBLEME DE LA NON-LINEARITE DES MATERIAUX (SATURATION LOCALE AU DEMARRAGE, GLOBALE AU SYNCHRONISME). L'UTILISATION DE COURBES B(H) EQUIVALENTES PERMET DE CONSERVER L'ENERGIE MAGNETIQUE DANS LE DOMAINE ETUDIE. ENFIN, L'IMPLANTATION DES EQUATIONS DE CIRCUIT PERMET DE TENIR COMPTE DES TETES DE BOBINES AU STATOR, DES ANNEAUX DE COURTS-CIRCUITS AU ROTOR ET D'AVOIR LA POSSIBILITE D'ALIMENTER EN TENSION. POUR POUVOIR SIMULER DES REGIMES TRANSITOIRES MECANIQUES OU ELECTRIQUES, IL A ETE NECESSAIRE DE DEVELOPPER D'UNE PART UN ALGORITHME PERMETTANT DE FAIRE TOURNER LE ROTOR SANS LE DEMAILLER (EN S'AFFRANCHISSANT DES MULTIPLES INCONVENIENTS QU'ENGENDRENT LES AUTRES METHODES EXISTANTES A CE SUJET) ET D'AUTRE PART UNE METHODE DE RESOLUTION EN PAS A PAS DANS LE TEMPS (TYPE PREDICTION-CORRECTION) AVEC COUPLAGE DE L'EQUATION MECANIQUE. UNE CONFRONTATION AVEC DES RESULTATS EXPERIMENTAUX EST FAITE AFIN DE VALIDER LES DIFFERENTES METHODES UTILISEES. LES RESULTATS OBTENUS MONTRENT QUE L'ENSEMBLE DES TRAVAUX EFFECTUES PERMET DE MODELISER DE FACON GENERALE, UN MOTEUR ASYNCHRONE PAR LA METHODE DES ELEMENTS FINIS

Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book is an important and diverse field of electric machines and drives. The twelve chapters of the book written by renowned authors, both academics and practitioners, cover a large part of the field of electric machines and drives. Various types of electric machines, including three-phase and single-phase induction machines or doubly fed machines, are addressed. Most of the chapters focus on modern control methods of induction-machine drives, such as vector and direct torque control. Among others, the book addresses sensorless control techniques, modulation strategies, parameter identification, artificial intelligence, operation under harsh or failure conditions, and modelling of electric or magnetic quantities in electric machines. Several chapters give an insight into the problem of minimizing losses in electric machines and increasing the overall energy efficiency of electric drives.

Available in PDF, EPUB and Kindle. Book excerpt: These two volumes provide in-depth coverage of 24 of history's most important inventors and their inventions. Who invented the sewing machine, the telephone, the internal combustion engine? Who pioneered vaccination? Who gave the world television, nylon, the nuclear reactor? The answers to some of these questions are straightforward, the answers to others much less so. All of them are explored in the fascinating Icons of Invention: The Makers of the Modern World from Gutenberg to Gates. This in-depth resource tells the stories of 24 of the most influential and well-known inventions of the modern age—and of the individuals most responsible for their development. Presented in chronological order, the entries provide background on the lives and work of inventors such as Thomas Edison, Alexander Fleming, and Tim Berners-Lee. At the same time, the set profiles their competitors and details the sometimes-controversial, often-mistake-plagued routes almost all of them took to their most famous creations.

Available in PDF, EPUB and Kindle. Book excerpt: The gripping history of electricity and how the fateful collision of Thomas Edison, Nikola Tesla, and George Westinghouse left the world utterly transformed. In the final decades of the nineteenth century, three brilliant and visionary titans of America’s Gilded Age—Thomas Edison, Nikola Tesla, and George Westinghouse—battled bitterly as each vied to create a vast and powerful electrical empire. In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires. At the heart of the story are Thomas Alva Edison, the nation’s most famous and folksy inventor, creator of the incandescent light bulb and mastermind of the world’s first direct current electrical light networks; the Serbian wizard of invention Nikola Tesla, elegant, highly eccentric, a dreamer who revolutionized the generation and delivery of electricity; and the charismatic George Westinghouse, Pittsburgh inventor and tough corporate entrepreneur, an industrial idealist who in the era of gaslight imagined a world powered by cheap and plentiful electricity and worked heart and soul to create it. Edison struggled to introduce his radical new direct current (DC) technology into the hurly-burly of New York City as Tesla and Westinghouse challenged his dominance with their alternating current (AC), thus setting the stage for one of the eeriest feuds in American corporate history, the War of the Electric Currents. The battlegrounds: Wall Street, the 1893 Chicago World’s Fair, Niagara Falls, and, finally, the death chamber—Jonnes takes us on the tense walk down a prison hallway and into the sunlit room where William Kemmler, convicted ax murderer, became the first man to die in the electric chair.

During college his professors explained that it was impossible to design an engine without commutators or brushes. Tesla was unconvinced that such was necessary or even particularly desirable. It was then that Tesla began his work on the rotating field motor that ultimately gave birth to the modern age. In May of 1888 Tesla delivered his lecture "A New System of Alternating Current Motors and Transformers"
