Book Description
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 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 stability Perfect 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.

Book Description
Use of conventional induction machines (IM) in adjustable speed drives (ASD) has increased in recent years. Electronic power processing has facilitated this increased use. The IM is an inexpensive and robust machine, but when used as part of an ASD, the cost of the system increases due to the inclusion of the power electronic converter. By using a single frame cascade induction machine (also referred to as a Brushless Doubly-Fed Machine or BDFM), which was first introduced in 1907 by Hunt [1], in conjunction with a power electronic converter, an alternative ASD system can be developed. The BDFM allows lower overall system cost since the power electronic converter is only required to process a fraction of the total power. The bulk of the power is fed directly from the 60 Hertz utility supply to the terminals of the machine. Redacted for Privacy This thesis details the analysis of the EDFM by use of computer simulation; the simulation is an updated detailed model first described by Wallace et al. [8-9]. The program gives time domain information on stator and rotor component currents as well as mechanical shaft speed. Development of a brushless castable rotor is presented. Design improvements to the basic rotor are discussed by changing rotor loop spacing and removal of rotor bars. Stator design is explored by varying the span and distribution of a double layer winding which allows two fields of different pole number to be produced by one stator. Further, employment of two isolated stator windings is discussed. Finally, predicted performance of the machine by simulation is compared qualitatively with actual machine measurements from a physical prototype to highlight the use of the simulation as a design tool.

Book Description
After a brief introduction to the main law of physics and fundamental concepts inherent in electromechanical conversion, Vector Control of Induction Machines introduces the standard mathematical models for induction machines – whichever rotor technology is used – as well as several squirrel-cage induction machine vector-control strategies. The use of causal ordering graphs allows systematization of the design stage, as well as standardization of the structure of control devices. Vector Control of Induction Machines suggests a unique approach aimed at reducing parameter sensitivity for vector controls based on a theoretical analysis of this sensitivity. This analysis naturally leads to the introduction of control strategies that are based on the combination of different controls with different robustness properties, through the use of fuzzy logic supervisors. Numerous applications and experiments confirm the validity of this simple solution, which is both reproducible and applicable to other complex systems. Vector Control of Induction Machines is written for researchers and postgraduate students in electrical engineering and motor drive design.

Book Description
This book provides a thorough approach for mastering the behavior and operation of induction motors, an essential device in the modern industrial world. Its way of presentation renders this book suitable for selfteaching by students, engineers, and researchers in the field of electrical engineering. It covers the modern theory of induction motor applications and control methods. The transient analysis of both three-phase and single-phase induction motors as well as that of the double-cage motors are developed. The principles of such modern control methods as Fiel-Oriented Control, Direct Torque Control and Computed Charges Acceleration Method are clearly treated in this monograph. Numerous equations, simulations, and figures are presented.

Book Description
With the growing interest in electrical machines in recent times, the multiphase machine field has developed into a fascinating research area. Their intrinsic features (power splitting, better fault tolerance, or lower torque ripple) make them an appealing competitor to conventional three-phase machines. Multiphase electric drives have been recently used in applications where fault tolerance and continuous operation of the drive are required. However, the difficulties in extending the three-phase conventional current regulation and control structure to multiphase systems still limit their broad applicability in industry solutions. The main objective of this book is to illustrate new advances, developments, and applications in the field of multiphase machines and drives, while exposing these advances, developments, and applications to the scientific community and industry.

Book Description
The Field Orientation Principle was fIrst formulated by Haase, in 1968, and Blaschke, in 1970. At that time, their ideas seemed impractical because of the insufficient means of implementation. However, in the early eighties, technological advances in static power converters and microprocessor-based control systems made the high-performance a. c. drive systems fully feasible. Since then, hundreds of papers dealing with various aspects of the Field Orientation Principle have appeared every year in the technical literature, and numerous commercial high-performance a. c. drives based on this principle have been developed. The term "vector control" is often used with regard to these systems. Today, it seems certain that almost all d. c. industrial drives will be ousted in the foreseeable future, to be, in major part, superseded by a. c. drive systems with vector controlled induction motors. This transition has already been taking place in industries of developed countries. Vector controlled a. c. drives have been proven capable of even better dynamic performance than d. c. drive systems, because of higher allowable speeds and shorter time constants of a. c. motors. It should be mentioned that the Field Orientation Principle can be used in control not only of induction (asynchronous) motors, but of all kinds of synchronous motors as well. Vector controlled drive systems with the so called brushless d. c. motors have found many applications in high performance drive systems, such as machine tools and industrial robots.
