Download or read book Global Warming and Climate Change written by Emma Carlson Berne and published by Referencepoint Press. This book was released on 2008 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world, the cause and impact of global warming and climate change is being passionately debated. While many claim that a climate crisis is imminent if greenhouse gases are not curbed, others argue that the effects have been overblown. Through objective overviews, primary sources, and full-color illustrations, this title will examine What Is Global Warming and Climate Change? What Are the Consequences of Global Warming? What Are the Controversies Surrounding Global Warming? What Are the Solutions for Global Warming?

Download or read book Machines synchrones double excitation written by Yacine Amara and published by ISTE Group. This book was released on 2023-03-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: La transition vers des usages propres et pérennes de l’énergie nécessite de développer des outils et des méthodes permettant d’étudier les objets électrotechniques afin d’assurer leur bon fonctionnement, et ce, le plus longtemps possible. Il faut pour cela disposer d’outils permettant d’appréhender leurs comportements, en tant que composant, mais aussi dans les systèmes où ils se trouvent, sur l’ensemble de leur cycle de vie. Machines synchrones à double excitation présente les outils nécessaires aux chercheurs, aux étudiants et aux ingénieurs en génie électrique pour analyser le fonctionnement des machines synchrones sur l’ensemble du plan d’opération. L’accent est mis sur les machines synchrones à double excitation (MSDE). La thématique des MSDE permet d’apporter des réponses à des problématiques fondamentales telles que le « défluxage » des machines à aimants permanents, l’optimisation énergétique, et enfin l’augmentation du coût des aimants permanents.

This book was released on 2013-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans un contexte ou la question de la preservation de l'environnement est devenue un sujet societal majeur, la recherche de nouvelles technologies pour remplacer la voiture a essence constitue un veritable enjeu industriel. Les vehicules hybrides et electriques sont une alternative prometteuse aux vehicules conventionnels. Ce travail porte sur la conception et l'optimisation des machines electriques pour la motorisation de ces voitures. Au cours de ces travaux, nous avons developpe une nouvelle methodologie de dimensionnement et d'optimisation des machines synchrones a double excitation. L'interet de cette methode est son bon compromis entre la precision et le temps de calcul et sa capacite d'adaptation a plusieurs types de machines. Le second volet de ce livre est consacre a la proposition d'une nouvelle structure de machine synchrone a rotor bobine. Une technique originale de compensation de la reaction magnetique d'induit est mise en place, elle consiste en l'insertion d'aimants secondaires permettant de creer un flux dans l'axe q de la machine. Ce dernier a pour role d'affaiblir le flux de la reaction magnetique d'induit.

Download or read book Permanent Magnet Synchronous Motor Drives for Gearless Traction Elevators written by Guoqiang Zhang and published by Springer. This book was released on 2022-02-25 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the control strategies for gearless permanent magnet synchronous motor traction elevators. Both basic principles and experimental evaluation have been addressed. This is achieved by providing in-depth study on a number of major topics such as speed detection at low-speed operation, starting torque strategy based on dichotomy and staircase methods, fuzzy self-tuning method, MPC and ADRC, etc. The comprehensive and systematic treatment of control strategies for cost-effective gearless PMSM traction elevators and practical issues are the major features of the book, which is particularly suited for readers who are interested to learn the control strategies for cost-effective gearless PMSM traction elevators. The book benefits researchers, engineers, and graduate students in the fields of ac motor drives and control strategies for cost-effective gearless PMSM traction elevators, etc.
