This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL EST RELATIF PLUS PARTICULIEREMENT A L'ETUDE CRISTALLOGRAPHIQUE DES RUBANS DE SILICIUM POLYCRISTALLIN ELABORES PAR LA METHODE EPR (ELECTRON POUDRE RUBAN). LES CONDITIONS DE CROISSANCE DE CES RUBANS CONDUISENT A DES STRUCTURES DE GRAINS ET DE JOINTS DE GRAINS PRESENTANT UN TAUX DE DEFAUTS PLUS OU MOINS ELEVE; LES DEFAUTS INTRAGRANULAIRES SONT CONSTITUES DE DISLOCATIONS ET DE MICROMACLES: LA DENSITE DE DISLOCATIONS VARIE DE 10#+#4 A 10#+#7/CM#2. LES DEFAUTS INTERGRANULAIRES SONT, LE PLUS SOUVENT, DES DISLOCATIONS ET DES DEFAUTS D'EMPILEMENT. L'ETUDE DE TEXTURE FAITE PAR DIFFRACTION X MONTRE QUE LA METHODE DE TIRAGE INDUIT UNE CRISTALLISATION NON ISOTROPE DES LE PREMIER PASSAGE DE LA ZONE FONDUE. SUR LES PRERUBANS, LES ORIENTATIONS (110) ET (331) APPARAISSENT MAJORITAIRES, CE QUI SE CONFIRME APRES LE SECOND PASSAGE DE LA ZONE FONDUE. CETTE ANALYSE COMPLETEE PAR UNE ETUDE ECP SUR LES GRAINS DE PLUS GRANDES DIMENSIONS MONTRE, POUR CES DERNIERS, UNE DOMINANTE D'ORIENTATION (111). L'UTILISATION D'UN GERME INITIAL DE CROISSANCE DE TAILLE (111) FAVORISE LE GROSSISSEMENT DE GRAINS POSSEDANT CETTE ORIENTATION TOUT EN AUGMENTANT LEUR NOMBRE. LES CARACTERISATIONS CRISTALLOGRAPHIQUE ET ELECTRIQUE RESPECTIVEMENT PAR M.E.T. ET EBIC-LBIC MONTRENT QUE LES JOINTS DE GRAINS SONT EN POSITION DE MACLES; LES UNS, AU CENTRE, CONSTITUES PAR DES INTERFACES A INDICES DE COINCIDENCE EXACTS CONDUISENT A UNE DIMINUTION DE 25% DU PHOTOCOURANT A LEUR NIVEAU, LES AUTRES, SUR LE BORD A INDICES CRISTALLOGRAPHIQUES NON DEFINIS, SONT PLUS ACTIFS PROVOQUANT UNE DIMINUTION DE 62% DU PHOTOCOURANT AVEC UNE VITESSE DE RECOMBINAISON A LEUR NIVEAU DE L'ORDRE DE 10#+#4 CM/S. LA LONGUEUR DE DIFFUSION RESTE COMPRISE ENTRE 18 ET 35 M. ENFIN, L'ANALYSE SIMS INDIQUE DES CONCENTRATIONS ELEVEES DE CARBONE ET D'OXYGENE REPARTIES DE 10#1#7 ET 10#1#8/CM#3 EN VOLUME

Download or read book Electric Machines and Drives written by Miroslav Chomat and published by BoD – Books on Demand. This book was released on 2011-02-28 with total page 278 pages. 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.
