This book was released on 2004 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail s'intéresse à l'étude des comportements électromagnétique et thermique du moteur à induction. Un état de l'art, où les méthodes courantes de modélisation électromagnétique et thermique du moteur à induction sont abordées, est d'abord dressé. Un modèle électromagnétique qui utilise la résolution par éléments finis 2D des équations du champ, en adoptant la représentation complexe, est développé. La prise en compte du mouvement du rotor par le couplage des champs dans l'entrefer, pour chaque harmonique d'espace, se fait par la méthode du double entrefer. Le principe de superposition permet de déterminer la solution finale. Afin de traiter les problèmes non linéaires, nous avons proposé une approche qui permet d'introduire des réluctivités équivalentes. Nous avons supposé que la saturation est due au seul premier harmonique d'espace. Un modèle thermique utilisant la méthode nodale est élaboré. La machine est découpée en 11 blocs élémentaires de forme cylindrique; le modèle global de la machine est composé de la juxtaposition des circuits thermiques correspondant à chaque bloc. Un couplage, au sens faible, des modèles électromagnétique et thermique est réalisé pour une détermination plus fine de la distribution de la température dans le moteur. Dans la phase de validation de nos calculs, nous avons conçu un banc d'essais qui permet des mesures spécifiques du couple et des températures. Les résultats des calculs, comparés aux mesures effectuées, sont satisfaisants.

Book Synopsis Routledge International Handbook of Ignorance Studies by : Matthias Gross
Download or read book Routledge International Handbook of Ignorance Studies written by Matthias Gross and published by Routledge. This book was released on 2015-05-15 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

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.
