The textbook bridges the gap between basic electromagnetic theory and practical industrial applications. Dr. J.B. Gupta uses an engineering-focused approach. He combines clear textual explanations with detailed circuit diagrams, phasor diagrams, and solved numerical problems [1]. The book is designed for undergraduate degrees (B.Tech/B.E.), diploma courses, and competitive examinations like GATE, IES, and AMIE. Core Topics Covered 1. Direct Current (DC) Machines
Before exams, utilize the formulas and key point summaries at the end of each chapter for quick revision. A Note on Accessing the PDF
The title itself emphasizes Performance . This means the book does not stop at explaining how a DC motor works; it goes deep into:
Double revolving field theory, starting mechanisms (split-phase, capacitor-start, shaded-pole), and characteristics. 5. Special and Fractional Kilowatt Motors The textbook bridges the gap between basic electromagnetic
