Electric Motor Drives

This book provides comprehensive, authoritative coverage of state-of-the-art motor drive technology. The area of electric motor drives is a multidisciplinary subject, the book therefore focuses on system-level modeling analysis, design, and integration of motor drives. The modeling and analysis of electrical machines and drive systems is systematically derived from first principles to assist students in under-standing the underlying basic concepts of the subject matter. The control algorithms are developed, and their implementations with simulation results are given wherever appropriate. Each of the motor drives is illustrated with an industrial application in detail at the end of chapters to enable students to relate theory to practice. Each chapter contains discussion questions to enhance learning, and to help students probe advanced topics independently with the help of references. This text fills the need for an up-to-date source of information on electric drives for students and professional engineers alike. Table of contents symbols. 1. Introduction. 2.
