Electrical Machines By Jb Gupta May 2026
"Electrical Machines" by J.B. Gupta is a comprehensive textbook widely utilized by engineering students, diploma holders, and aspirants of competitive examinations (such as GATE, ESE, and various state power utility exams) in India. The book is renowned for its exhaustive coverage of theoretical concepts combined with a vast repository of solved numerical problems. It serves as a bridge between academic curriculum requirements and the practical application required for competitive exams.
Gupta is famous for his "numerical heavy" approach. A single chapter on DC Shunt Motors might contain 40+ solved numerical problems covering everything from basic back EMF to complex speed control using series-parallel combinations.
J.B. Gupta’s Electrical Machines is a superb problem bank and exam guide, not a primary learning textbook for deep conceptual clarity.
If you already understand the basic principles from class or another source, this book will help you solve problems fast and crack exams. For beginners, pair it with a stronger theory book.
Best for: University exam prep, GATE/IES aspirants, revision time.
Not best for: Research, design, or first-time learners without guidance.
