    AC Motor Control and Electrical Vehicle Applications provides a guide to the control of AC motors with a focus on its application to electric vehicles (EV). It describes the rotating magnetic flux, based on which dynamic equations are derived. The text not only deals with the induction motor, but covers the permanent magnet synchronous motors (PMSM). Additionally, the control issues are discussed by taking into account the limitations of voltage and current. The latest edition includes more experimental data and expands upon the topics of inverter, pulse width modulation methods, loss minimizing control, and vehicle dynamics. Various EV motor design issues are also reviewed, while comparing typical types of PMSMs.


    • Considers complete dynamic modeling of induction and PMSM in the rotating frame.

    • Provides various field-oriented controls, while covering advanced topics in PMSM high speed control, loss minimizing control, and sensorless control.

    • Covers inverter, sensors, vehicle dynamics, driving cycles, etc., not just motor control itself.

    • Offers a comparison between BLDC, surface PMSM, and interior PMSM.

    • Discusses how the motor produces torque and is controlled based on consistent mathematical treatments.

    Dr. Kwang Hee Nam received his B.S. degree in chemical technology and his M.S. degree in control and instrumentation from Seoul National University in 1980 and 1982, respectively. He also earned an M.A. degree in mathematics and a Ph.D. degree in electrical engineering from the University of Texas at Austin in 1986. Since 1987, he has been at POSTECH, where he is now a Professor of electrical engineering. From 1987 to 1992, he participated in the Pohang Light Source (PLS) project as a beam dynamics group leader. He performed electron beam dynamic simulation studies, and designed the magnet lattice for the PLS storage ring. He also served as the director of POSTECH Information Research Laboratories from 1998 to 1999. He is the author of over 150 publications in motor drives and power converters and received a best paper award from the Korean Institute of Electrical Engineers in 1992 and a 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 a president of Korean Institute of Power Electronics in 2016. Presently, his research areas include sensorless control, EV propulsion systems, motor design, and EV chargers.
