AC Motor Control and Electrical Vehicle Applications 2nd Edition by Kwang Hee Nam | PDF Free Download.
Dr. Kwang Hee Nam received his B.S. in chemical technology and his M.S. in control and instrumentation from Seoul National University in 1980 and 1982, respectively.
He also earned an M.A. in mathematics and a Ph.D. in electrical engineering from the University of Texas at Austin in 1986. Since 1987, he has been at POSTECH as a professor of the department of electrical engineering.
From 1987 to 1992, he participated in constructing a 2.5 GeV synchrotron light source as a beam dynamics group leader. He also served as the director of POSTECH Information Research Laboratories from 1998 to 1999.
He published more than 150 publications in motor drives and power converters and received the best paper award from the Korean Institute of Electrical Engineers in 1992 and the best transaction paper award from the Industrial Electronics Society of IEEE in 2000.
Dr. Nam has worked on numerous industrial projects for major Korean industries such as POSCO, Hyundai Motor Company, LG Electronics, and Hyundai Mobis.
He served as president of the Korean Institute of Power Electronics in 2016. Presently, his research areas include sensorless control, EV propulsion systems, motor design, and EV chargers
The importance of motor control technology has resurfaced recently since the electrification of various power sources reduces greenhouse gas.
Autonomous vehicle technology opens a new world of unmanned delivery with the expansion of drone applications. Sooner or later, electric planes and flying cars are popularly used for passenger transport. The motor application is more accelerated as the battery costs are reduced.
Control engineers need to understand many motor design issues to meet challenging design specifications. From this point of view, various aspects including motor control, motor design, practical manufacturing, testing, and programming are considered in this book.
This book was written as a textbook for a graduate-level course on AC motor control and electric drive. Not only the motor control but also some motor design basics are covered to give a comprehensive view of the multidisciplinary age.
Theoretical integrity in the modeling and control of AC motors is pursued throughout the book. In the second edition, many EV projects and teaching experiences at POSTECH and industrial sites are reflected.
The contents become richer by adding more exercises and problems that utilize Excel spreadsheets and MATLAB Simulink. There is a little barrier for the beginners to understand the principles of the AC rotating machine because many physical phenomena are interpreted in the moving frame.
The essential machinery is the ability to understand voltage to current dynamics in the rotating frame. Firstly, this book is focused on illustrating how the rotating field is synthesized with the three-phase winding.
Also, the benefits of coordinate transformation are stressed in the dynamic modeling of AC motors. For example, many mathematical tools are utilized to show how the voltage and current limits affect torque maximization.
Loss minimizing and sensorless controls are also covered. In the second part of this book, many issues regarding EV motor design and fabrication are expressed.
In Chapters 11 and 12, a motor design method is suggested based on the requirements of power, torque, power density, etc. under voltage and current limits.
In addition, the experimental procedures and inverter programming techniques are introduced that provide an optimal current control strategy under varying (battery) voltage conditions.
In the last part, the basics of vehicle dynamics and EV power trains are shown including calculation methods of driving range and efficiency of the vehicle.
This book is intended to bring combined knowledge and problems to the students who wish to learn the electric power train. So a fusing approach is attempted while covering control, signal processing, electromagnetics, power electronics, material properties, vehicle dynamics, etc.
Many control issues that can lead to on-going research are discussed. Finally, the authors would like to say a word of thanks to the family who supported me and encouraged me.
Also, many thanks are given to Jongwon Choi, Yoonjae Kim, Bonkil Koo, Jeonghun Lee, Minhyeok Lee, Taeyeon Lee, Pooreum Jang, and Heekwang Lee who helped me by providing many solutions, simulation results, and interesting reflections.
