Introducing a new edition of the popular reference on machine analysis Now in a fully revised and expanded edition, this widely used reference on machine analysis boasts many changes designed to address the varied needs of engineers in the electric machinery, electric drives, and electric power industries. The authors draw on their own extensive research efforts, bringing all topics up to date and outlining a variety of new approaches they have developed over the past decade. Focusing on reference frame theory that has been at the core of this work since the first edition, this volume goes a step further, introducing new material relevant to machine design along with numerous techniques for ...
This text provides a basic treatment of modern electric machine analysis that gives readers the necessary background for comprehending the traditional applications and operating characteristics of electric machines—as well as their emerging applications in modern power systems and electric drives, such as those used in hybrid and electric vehicles. Through the appropriate use of reference frame theory, Electromagnetic Motion Devices, Second Edition introduces readers to field-oriented control of induction machines, constant-torque, and constant-power control of dc, permanent-magnet ac machines, and brushless dc machines. It also discusses steady-state and transient performance in addition ...
The updated third edition of the classic book that provides an introduction to electric machines and their emerging applications The thoroughly revised and updated third edition of Electromechanical Motion Devices contains an introduction to modern electromechanical devices and offers an understanding of the uses of electric machines in emerging applications such as in hybrid and electric vehicles. The authors—noted experts on the topic—put the focus on modern electric drive applications. The book includes basic theory, illustrative examples, and contains helpful practice problems designed to enhance comprehension. The text offers information on Tesla's rotating magnetic field, which is ...
An introduction to the analysis of electric machines, power electronic circuits, electric drive performance, and power systems This book provides students with the basic physical concepts and analysis tools needed for subsequent coursework in electric power and drive systems with a focus on Tesla’s rotating magnetic field. Organized in a flexible format, it allows instructors to select material as needed to fit their school’s power program. The first chapter covers the fundamental concepts and analytical methods that are common to power and electric drive systems. The subsequent chapters offer introductory analyses specific to electric machines, power electronic circuits, drive system pe...
Discover the history, underpinnings, and applications of one of the most important theories in electrical engineering In Reference Frame Theory, author Paul Krause delivers a comprehensive and thorough examination of his sixty years of work in reference frame theory. From the arbitrary reference frame, to the coining of the title "reference frame theory," to the recent establishment of the basis of the theory, the author leaves no stone unturned in his examination of the foundations and niceties of this area. The book begins with an integration of Tesla's rotating magnetic field with reference frame theory before moving on to describe the link between reference frame theory and symmetrical i...
Discover the analytical foundations of electric machine, power electronics, electric drives, and electric power systems In Introduction to the Analysis of Electromechanical Systems, an accomplished team of engineers delivers an accessible and robust analysis of fundamental topics in electrical systems and electrical machine modeling oriented to their control with power converters. The book begins with an introduction to the electromagnetic variables in rotatory and stationary reference frames before moving onto descriptions of electric machines. The authors discuss direct current, round-rotor permanent-magnet alternating current, and induction machines, as well as brushless direct current an...
A devilishly funny collection of comics that explores our most gruesome, hilarious, and bizarre fears—and the dangers lurking around every corner. We all have strange, irrational fears—from seeing ghosts in the bedroom mirror to being sucked into a mall escalator or finding yourself miles below the ocean's surface on the deck of a sunken ship. In Deep Dark Fears, animator, illustrator, and cartoonist Fran Krause brings these fears to life in 101 vividly illustrated comics inspired by his wildly popular web comic and based on real fears submitted by online readers. Deep Dark Fears reveals a primal part of our humanity and highlighting both our idiosyncrasies and our similarities.
Tolle Lege, take up and read! These words from St. Augustine perfectly describe the human condition. Reading is the universal pilgrimage of the soul. In reading we journey to find ourselves and to save ourselves. The ultimate journey is reading the Great Books. In the Great Books we find the struggle of the human soul, its aspirations, desires, and failures. Through reading, we find faces and souls familiar to us even if they lived a thousand years ago. The unread life is not worth living, and in reading we may well discover what life is truly about and prepare ourselves for the pilgrimage of life.
Bernie Krause is the world's leading expert in natural sound. Beginning by recording the sound of wheat growing in a Kansas field, he has spent the last 40 years recording ecological soundscapes and the sounds of over 15,000 species. Due to human actions, half of the wild soundscapes he has on tape no longer exist. Krause divides natural sound into three categories. Biophony is the sound made by animals and plants, like the shrimp whose underwater clicks are equivalent to a Boeing 727 taking off. Geophony is natural sound - made by wind, water and rain - which led different tribes to have different musical scales. And anthrophony is human-generated sound, which as it has rapidly increased ha...
