Introduction to AC Machine Design
The only book on the market that emphasizes machine design beyond the basic principles of AC and DC machine behavior AC electrical machine design is a key skill set for developing competitive electric motors and generators for applications in industry, aerospace, and defense. This book presents a thorough treatment of AC machine design, starting from basic electromagnetic principles and continuing through the various design aspects of an induction machine. Introduction to AC Machine Design includes one chapter each on the design of permanent magnet machines, synchronous machines, and thermal design. It also offers a basic treatment of the use of finite elements to compute the magnetic field ...
Pulse Width Modulation for Power Converters
* The first single volume resource for researchers in the field who previously had to depend on separate papers and conference records to attain a working knowledge of the subject. * Brings together the field's diverse approaches into an integrated and comprehensive theory of PWM
Analysis of Synchronous Machines
Analysis of Synchronous Machines, Second Edition is a thoroughly modern treatment of an old subject. Courses generally teach about synchronous machines by introducing the steady-state per phase equivalent circuit without a clear, thorough presentation of the source of this circuit representation, which is a crucial aspect. Taking a different approach, this book provides a deeper understanding of complex electromechanical drives. Focusing on the terminal rather than on the internal characteristics of machines, the book begins with the general concept of winding functions, describing the placement of any practical winding in the slots of the machine. This representation enables readers to clea...
Approaching Monumentality in Archaeology
Interdisciplinary study of monumental art and architecture in human history. Monumentality is a human phenomenon that has occurred in nearly all times and places. Because of its ubiquity, monumentality is something that has been studied by a large number of disciplines and individuals. Approaching Monumentality in Archaeology explores the phenomenon of monumental art and architecture from humankinds most ancient past to recent history, and does so using an interdisciplinary approach that incorporates the research of anthropological archaeologists, art historians, classicists, and sociologists working in a wide variety of historical and cultural contexts. The volume seeks to define what is meant by the terms monument and monumentality, and to understand the social and political significance of monument-building as it has manifested around the world. By advocating for a relational approach to the topic that seeks to find monumentality in the ongoing relationship between object and person, this book offers the opportunity to begin the process of uniting these varied interests into a unified discourse.
Handbook of Archaeological Theories
This handbook, a companion to the authoritative Handbook of Archaeological Methods, gathers original, authoritative articles from leading archaeologists on all aspects of the latest thinking about archaeological theory. It is the definitive resource for understanding how to think about archaeology.
Modern Electrical Drives
Electrical drives lie at the heart of most industrial processes and make a major contribution to the comfort and high quality products we all take for granted. They provide the controller power needed at all levels, from megawatts in cement production to milliwatts in wrist watches. Other examples are legion, from the domestic kitchen to public utilities. The modern electrical drive is a complex item, comprising a controller, a static converter and an electrical motor. Some can be programmed by the user. Some can communicate with other drives. Semiconductor switches have improved, intelligent power modules have been introduced, all of which means that control techniques can be used now that were unimaginable a decade ago. Nor has the motor side stood still: high-energy permanent magnets, semiconductor switched reluctance motors, silicon micromotor technology, and soft magnetic materials produced by powder technology are all revolutionising the industry. But the electric drive is an enabling technology, so the revolution is rippling throughout the whole of industry.
Celebrity Arms in a Day: Body Sculpting with the New Interactive Lipo Method
Do you want to have a sculpted, tone body that everybody will admire? DR. THOMAS SU, is the creator of the new and innovative Interactive Lipo Method for body sculpting. Having a Fine Arts degree and a background as an artist prior to attending medical school, Dr. Su has a unique perspective in sculpting the human body through liposuction. Dr. Su uses his skills as a human figure artist and an experienced cosmetic surgeon to take a portion of the human figure, visualize the beauty within, and transform it into a living work of art. His new Interactive Lipo Method can be used to create the Celebrity Arms look and to sculpt other body areas to reveal underlying muscle definition. This new method achieves dramatic results that cannot be achieved with any traditional method of cosmetic surgery. This exciting new book contains numerous illustrations drawn by Dr. Su, and many before and after color photographs from actual clinical cases performed at his liposuction clinic, Artistic Lipo. It is a must read for both prospective patients and experienced liposuction surgeons who desire to incorporate the Interactive Lipo Method into their liposuction practice.
AC and DC Network Theory
Whatever the field of human activity-domestic or scientific, work or leisure-it is likely that some knowledge of the behaviour of electrical circuits is required to keep the processes moving, the wheels turning. In many cases, a knowledge of Ohm's law may suffice. In others, an understanding of more complex relationships may be necessary. In this book an attempt is made to provide, in a concise manner, an introduction to the main methods of treating electrical networks, whether they be carrying direct (de) or alternating (ac) electrical currents. Clearly, the range of possible circuits is vast so that the simplifications which are demonstrated in the pages that follow are of great importance...
Analysis and Control of Electric Drives
A guide to drives essential to electric vehicles, wind turbines, and other motor-driven systems Analysis and Control of Electric Drives is a practical and comprehensive text that offers a clear understanding of electric drives and their industrial applications in the real-world including electric vehicles and wind turbines. The authors—noted experts on the topic—review the basic knowledge needed to understand electric drives and include the pertinent material that examines DC and AC machines in steady state using a unique physics-based approach. The book also analyzes electric machine operation under dynamic conditions, assisted by Space Vectors. The book is filled with illustrative exam...
