Modern Permanent Magnet Electric Machines Theory and Control

Modern Permanent Magnet Electric Machines Theory and Control

The late 1980s saw the beginning of the PM brushless machine era with the invention of high-energy density permanent magnets (PM) and the development of power electronics. Although induction motors are now the most popular electric motors the impact of PM brushless machines on electromechanical drives is significant. Today PM machines come second to induction machines. Replacement of electromagnetic field excitation systems by PMs brings the following benefits: No electrical energy is absorbed by the field excitation system and thus there are no excitation losses causing substantial increase in efficiency Higher power density (kW/kg) and/or torque density (Nm/kg) than electromagnetic excitation Better dynamic performance than motors with electromagnetic excitation (higher magnetic flux density in the air gap) Simplification of construction and maintenance Less expensive for some types of machines Modern Permanent Magnet Electric Machines: Theory and Control serves as a textbook for undergraduate power engineering students who want to supplement and expand their knowledge in the fundamentals of magnetism soft magnetic materials permanent magnets (PMs) calculation of magnetic circuits with PMs modern PM brushed DC machines and their controls modern PM brushless DC motors and drive control and modern PM generators. The book can help students learn more about electrical machines and can serve as a prescribed text for teaching elective undergraduate courses such as modern permanent magnet electrical machines. Since the book is written in a simple scientific language and without redundant mathematics it can also be used by practicing engineers and managers employed in electrical machinery or electromagnetic device industries. | Modern Permanent Magnet Electric Machines Theory and Control

With its comprehensive coverage of the state of the art this Second Edition introduces basic types of transformers and electric machines. Classifications and characterization—modeling and performance—of power electric transformers (single and multiphase) motors and generators commercial machines (dc brush induction dc excited synchronous PM synchronous reluctance synchronous) and some new ones (multiphase ac machines switched reluctance machines) with great potential for industry with rotary or linear motion are all treated in the book. The book covers in detail circuit modeling characteristics and performance characteristics under steady state testing techniques and preliminary electromagnetic-thermic dimensioning with lots of solved numerical examples and special cases to illustrate new electric machines with strong industrialization potential. All formulae used to characterize parameters and performance may be safely used in industry for preliminary designs and have been applied in the book through numerical solved examples of industrial interest. Numerous computer simulation programs in MATLAB® and Simulink® that illustrate performance characteristics present in the chapters are included and many be used as homework to facilitate a deeper understanding of fundamental issues. This book is intended for a first-semester course covering electric transformers rotary and linear machines steady-state modeling and performance computation preliminary dimensioning and testing standardized and innovative techniques. The textbook may be used by R&D engineers in industry as all machine parameters and characteristics are calculated by ready-to-use industrial design mathematical expressions. | Electric Machines Steady State and Performance with MATLAB®

Critically Ill Children and the Law Medical Decision-Making and the Best Interests Principle

Critically Ill Children and the Law Medical Decision-Making and the Best Interests Principle

A series of recent high-profile court cases has demonstrated the inadequacy of current laws in addressing issues relating to medical treatment decisions involving seriously ill children. The challenges of determining that life-sustaining medical treatment is not in a young child’s best interests have resulted in criticism of the best interests principle. This book explores the theoretical foundations of the best interests principle and alternatives offered in the academic literature to allow readers to understand why the principle remains contentious despite its prevalence. It provides theoretical background exploration of what occurs in practice and proposes a novel approach to address these challenges. Frameworks for decision-making identified in the academic literature are used to examine the application of the best interests principle in practice in England and Wales Australia and New Zealand through a review of the case law and qualitative research with paediatric doctors. The exploration of current practice allows readers to understand the challenges of applying the best interests principle but also the need to retain a focus on the child. Readers are introduced to a human-rights based approach which ensures that the focus remains on upholding the child’s best interests but also provides a more comprehensive explanation of the situation. Progressing the debate around end-of-life decision-making and children the book will be a valuable resource for academics researchers and policy-makers. It will also provide practical guidance to both legal and medical practitioners in managing disputes about the provision of life-sustaining treatment. | Critically Ill Children and the Law Medical Decision-Making and the Best Interests Principle

Executive Talent Developing and Keeping the Best People

Executive Talent Developing and Keeping the Best People

This brilliant up-to-date compendium argues that the most successful factor in company life is good people: individuals who are capable competent and savvy. Can corporate life attract such people? Ginzberg argues that despite demographic dislocations and the challenges to the work ethic the answer to this question is a loud yes. In Executive Talent Ginzberg and his colleagues show how to attract train and promote a superior work force and how to take advantage of the different values in today's employees. Over 25 percent of the population currently graduates from a senior college and the number going for advanced degrees is climbing. Blacks and Hispanics together will soon account for one in every four new native-born job applicants. Women are now nearly as prevalent in the work force as men. Today's employees place more emphasis on family and leisure and less on company loyalty. In the face of these critical changes companies can no longer continue with the same human resource policies. Ginzberg offers new approaches to attract and retain superior talent. In Executive Talent Ginzberg brings together top academics and high level executives to explore the new world of work. They discuss coming trends and changes that will reshape the talent pool how these shifts will impact the individual company and ways to develop and implement a human resource strategy to meet the challenging work force of the future. | Executive Talent Developing and Keeping the Best People

Red Magic The World’s Best Fairy Tales Collected and Arranged by Romer Wilson

Red Magic The World’s Best Fairy Tales Collected and Arranged by Romer Wilson

With a Preface and biographies from Jack Zipes as well as the original illustrations by Kay Nielsen this collection of fairy tales originally published by the award-winning Romer Wilson – Green Magic (1928) Silver Magic (1929) and Red Magic (1930) – offers a combination of classic fairy tales alongside lesser known global and diverse tales. Red Magic contains such classics as “Aladdin and the Wonderful Lamp” from the Arabian Nights “A Child’s Dream on a Star” by Dickens and “The Chimera” by Hawthorne. It also contains previously unpublished tales such as “Princess Silver Silk” and “The Enchanted Deer. ” It was Romer Wilson’s intention to combine the familiar with the unknown and to introduce authors and cultures from a variety of countries. As a researcher Wilson uncovered a remarkable amount of stories from other countries that remain unknown today. This collection gives voice to unique and intriguing tales that inspire children to have a better understanding of how people and their stories are alike despite major differences. Through his Preface and commentary Jack Zipes shows how all three books are a means to bring people together in the name of peace and justice. These books will therefore be of interest to anyone researching or studying fairy tales folklore and children’s literature as well as global or comparative literature and social justice. | Red Magic The World’s Best Fairy Tales Collected and Arranged by Romer Wilson
