Power Circuits and Electromechanics is intended to serve as a one semester introductory course in power circuits and electromechanical energy conversion. In many curricula, the traditional circuit theory course is being replaced by a course in analog processing. The students should have basic exposure to KCL, KVL and simple circuits as well as a course in field theory or electromagnetism before taking this course. The book is basically in three modules. The first module covers complex power in single and three phase circuits, analysis of magnetic circuits, mutually coupled circuits and single phase transformers. The second module, drawing upon the quasi-static approximation of magnetic field equations, develops the concepts of electromechanical energy conversion, forces of electric origin leading to the dynamics equations of motion of the electromechanical system. A brief introduction to state space modeling, static equilibrium and stability is included. The third module discusses in the energy, co-energy framework, the torque of electric origin in synchronous, induction and DC machines. In each case, the equivalent circuit for the machine for steady state operation is developed for analysis purposes. A brief discussion of single phase motors is presented at the end.

This comprehensive introduction to electromechanical devices and their underlying principles of operation gives technicians of manufacturing and processign systems the unified treatment of mechanical and electrical topics so much in demand in today's workplace. Practical, hands-on information related to operating, installing, troubleshooting, and servicing a wide range of electromechanical systems is presented. Chapter topics cover number notation, measurement, and units; linear motion; principles of simple machines and the lever; pulleys, wheel and axle, and the inclined plane; friction, lubrication, and bearings; work, energy, torque, and power; rotational power transmission; rotation, translation, and intermittent motion devices; the electric circuit; electromagnetic circuits and devices; transformers and power distribution; overcurrent protection; sequential process control; alternating current electric motors; direct-current motors and ac drives; and concepts of automatic control systems. A self-paced study guide for employed technicians and maintenance engineers working independently to upgrade themselves.

Provides detailed, clear explanations of the fundamentals of electrical engineering, keeping readers focused on the basics. Maintains a strong emphasis on vocabulary throughout, encouraging further thought and communication based on chapter discussions. This book carefully explores the unifying themes of Electrical Engineering, maintaining a low level of detail and abstract theory. Topics include: Electric Power Systems, The Physical Basis of Electromechanics, Magnetic Structures and Electrical Transformers, The Synchronous Machine, Induction Motors, Direct-Current Motors, Power Electronic Systems.

A top-down approach that enables readers to master and apply core principles Using an innovative top-down approach, this text makes it possible for readers to master and apply the principles of contemporary power electronics and electromechanic power conversion, exploring both systems and individual components. First, the text introduces the role and system context of power conversion functions. Then the authors examine the building blocks of power conversion systems, describing how the components exchange power. Lastly, readers learn the principles of static and electromechanic power conversion. The Principles of Electronic and Electromechanic Power Conversion opens with a chapter that introduces core concepts in electrical systems and power conversion, followed by a chapter dedicated to electrical power sources and energy storage. Next, the book covers: Power, reactive power, and power factor Magnetically coupled networks Dynamics of rotational systems Power electronic converters DC machines AC machines The text offers readers a concise treatise on the basic concepts of magnetic circuits. Its simple approach to machines makes the principles of field-oriented control and space vector theory highly accessible. In order to help readers fully grasp power electronics, the authors focus on topologies that use a series transistor and diode combination connected to a DC source, a standard building block of today’s power conversion systems. Problem sets at the end of each chapter enable readers to fully master each topic as they progress through the text. In summary, The Principles of Electronic and Electromechanic Power Conversion provides the most up-to-date, relevant tools needed by today’s power engineers, making it an ideal undergraduate textbook as well as a self-study guide for practicing engineers.

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 the foundation of reference frame theory and explores in detail the reference frame theory. The authors also review permanent-magnet ac, synchronous, and induction machines. In each chapter, the material is arranged so that if steady-state operation is the main concern, the reference frame derivation can be de-emphasized and focus placed on the steady state equations that are similar in form for all machines. This important new edition: • Features an expanded section on Power Electronics • Covers Tesla's rotating magnetic field • Contains information on the emerging applications of electric machines, and especially, modern electric drive applications • Includes online animations and a solutions manual for instructors Written for electrical engineering students and engineers working in the utility or automotive industry, Electromechanical Motion Devices offers an invaluable book for students and professionals interested in modern machine theory and applications.
