Electric motor drives aim to provide an in-depth understanding of the working of various types of electrical motor drives. The text is spread across twenty chapters under the five broad clusters, namely Electric motor drive characteristics, DC motor drives, AC motor drives, Special motor drives and Industrial drive applications. MATLAB® programs and PSIM simulations featured in the text aids in determining the characteristics of electric motor drives and machines and offers a profound new perspective in the design of power electronic circuits and controllers for electric motors. Features: - Includes over 70 example problems, solved using a stepwise approach. - An entire chapter devoted to simulation studies with controller and power electronic circuits for electric motors using PSIM software. - Comprises over 450 and 150 end-of-chapter review questions and exercises, to help readers in preparing for semester exams and enhance the understanding of the subject. - Includes over 150 multiple choice questions with answers covering the syllabi of GATE and UPSC exams. - Associated simulation files are available on the Companion Web site.
