: Principles of converting electrical energy to mechanical energy (and vice-versa) using magnetic fields. Rotating Machine Concepts
In electrical engineering, especially when studying machines, having a reliable textbook is crucial. Books like J.B. Gupta's, along with others by authors such as Dr. P.S. Bhimbra (Khanna Publishing) and D.P. Kothari & I.J. Nagrath (McGraw Hill Education), form the core curriculum for electrical machine design, testing, and performance analysis.
Excellent for university semester exams because it matches the standard syllabus of most technical universities. electrical machines by jb gupta
The theoretical explanations are concise and exam-oriented. Unlike heavy reference texts (such as Fitzgerald or Nagrath & Kothari) which focus heavily on derivations and physics, Gupta’s approach focuses on the results and their application . The concepts are presented in bullet points or structured paragraphs that are easy to memorize.
Single-phase and three-phase transformers.
| | How to use this book | |----------------|--------------------------| | Beginners (1st time studying machines) | Read theory from a more detailed book (e.g., Electrical Machinery by P.S. Bimbhra or Electric Machinery by Fitzgerald) first, then use J.B. Gupta for problems. | | Exam cramming (GATE/IES/university) | Skip long derivations – focus on solved problems, formulas, and short-answer questions at the end of each chapter. | | Practicing for numericals | Work through all unsolved problems – answers are given at the end of the book. This is where the real practice value lies. | | Lab or project work | This book is not ideal for that. Use a practical design manual instead. |
At the end of each chapter, the book includes a mix of theoretical questions, unsolved numerical problems with answers, and multiple-choice questions (MCQs) sourced from past competitive exams. because it makes high-level concepts accessible and engaging

The Ultimate Guide to Electrical Machines by JB Gupta: A Comprehensive Review for Engineering Students
The book is typically available in two formats: as a single comprehensive volume ("Theory & Performance of Electrical Machines") or split into specific volumes covering Alternating Current (AC) and Direct Current (DC) machines. Key Topics Covered in the Book
Do not skip the introductory chapters on electromagnetism. Every machine—whether a transformer or a motor—is just a fancy magnetic circuit. If you don't understand reluctance, permeance, and hysteresis, the later chapters will confuse you. Kataria & Sons
Reviewers on platforms like Quora often compare J.B. Gupta with other authors like P.S. Bimbhra. While Bimbhra is often cited for its compactness, J.B. Gupta is praised for its and exhaustive question bank. It is particularly recommended for students who prefer a "step-by-step" approach or those who need a high volume of practice problems to build confidence. Summary of Benefits Comprehensive Theory
