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 making the derivation of equations more direct and easy to use. Coverage includes: Completely new chapters on winding functions and machine design that add a significant dimension not found in any other text A new formulation of machine equations for improving analysis and modeling of machines coupled to power electronic circuits Simplified techniques throughout, from the derivation of torque equations and synchronous machine analysis to the analysis of unbalanced operation A unique generalized approach to machine parameters identification A first-rate resource for engineers wishing to master cutting-edge techniques for machine analysis, Analysis of Electric Machinery and Drive Systems is also a highly useful guide for students in the field.

Introduction to Modern Analysis of Electric Machines and DrivesComprehensive resource introducing magnetic circuits and rotating electric machinery, including models and discussions of control techniquesIntroduction to Modern Analysis of Electric Machines and Drives is written for the junior or senior student in Electrical Engineering and covers the essential topic of machine analysis for those interested in power systems or drives engineering. The analysis contained in the text is based on Tesla's rotating magnetic field and reference frame theory, which comes from Tesla's work and is presented for the first time in an easy to understand format for the typical student.Since the stators of synchronous and induction machines are the same for analysis purposes, they are analyzed just once. Only the rotors are different and therefore analyzed separately. This approach makes it possible to cover the analysis efficiently and concisely without repeating derivations. In fact, the synchronous generator equations are obtained from the equivalent circuit, which is obtained from work in other chapters without any derivation of equations, which differentiates Introduction to Modern Analysis of Electric Machines and Drives from all other textbooks in this area.Topics explored by the two highly qualified authors in Introduction to Modern Analysis of Electric Machines and Drives include:* Common analysis tools, covering steady-state phasor calculations, stationary magnetically linear systems, winding configurations, and two- and three-phase stators* Analysis of the symmetrical stator, covering the change of variables in two- and three-phase transformations and more* Symmetrical induction machines, covering symmetrical two-pole two-phase rotor windings, electromagnetic force and torque, and p-pole machines* Direct current machines and drives, covering commutation, voltage and torque equations, permanent-magnet DC machines, and DC drivesIntroduction to Modern Analysis of Electric Machines and Drives is appropriate as either a first or second course in the power and drives area. Once the reader has covered the material in this book, they will have a sufficient background to start advanced study in the power systems or drives areas.

Discover the analytical foundations of electric machine, power electronics, electric drives, and electric power systemsIn 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 and induction motor drives. Synchronous generators and various other aspects of electric power system engineering are covered as well, showing readers how to describe the behavior of electromagnetic variables and how to approach their control with modern power converters.Introduction to the Analysis of Electromechanical Systems presents analysis techniques at an introductory level and at sufficient detail to be useful as a prerequisite for higher level courses. It also offers supplementary materials in the form of online animations and videos to illustrate the concepts contained within. Readers will also enjoy:* A thorough introduction to basic system analysis, including phasor analysis, power calculations, elementary magnetic circuits, stationary coupled circuits, and two- and three-phase systems* Comprehensive explorations of the basics of electric machine analysis and power electronics, including switching-circuit fundamentals, conversion, and electromagnetic force and torque* Practical discussions of power systems, including three-phase transformer connections, synchronous generators, reactive power and power factor correction, and discussions of transient stabilityPerfect for researchers and industry professionals in the area of power and electric drives, Introduction to the Analysis of Electromechanical Systems will also earn its place in the libraries of senior undergraduate and graduate students and professors in these fields.
