If you have the J.B. Gupta PDF, it is likely an MCQ bank. It is not recommended to use it as your primary textbook for learning concepts because it lacks detailed derivations and explanations.
Best Strategy:
Disclaimer regarding PDFs: Sharing or downloading copyrighted PDF files of authors like J.B. Gupta without purchasing is illegal and violates copyright laws. It is recommended to buy the physical book from a local bookstore or online platforms like Amazon or Flipkart, as the quality of diagrams in physical copies is far superior for engineering studies.
An interesting and distinctive feature of J.B. Gupta’s Electrical Machines-II
emphasis on mathematical modeling to predict real-world performance
. Rather than just providing descriptive theory, the book provides detailed derivations of equivalent circuits
for complex AC machines like synchronous and induction motors. New York University This specific approach allows you to: Bridge Theory and Practice
: It shows exactly how theoretical parameters—like leakage flux and magnetizing currents—relate to physical, measurable data in an industrial setting. Simplify Complex Systems : It heavily utilizes the per-unit system
, which simplifies large-scale power system calculations by normalizing different voltage and power levels into a single scale. Predict Machine Behavior
: By focusing on power-angle characteristics and voltage regulation, the book helps you mathematically predict how a machine will behave under specific load conditions before it is even switched on. New York University The book is structured as a text-cum-guide
, featuring a vast collection of solved numerical problems that make it a favorite for students preparing for competitive exams like New York University specific machine type

Title: 📚 Where to Find Electrical Machines 2 by J.B. Gupta (PDF) – A Practical Guide
Post:
Hey electrical engineering family! ⚡
I’ve seen a lot of requests for "Electrical Machines 2" by J.B. Gupta in PDF form. This book is a go-to for understanding Synchronous Machines, Alternators, Parallel Operation, and Transients – basically the core of your 4th/5th semester EE curriculum.
First, the honest truth: There is no official, legal free PDF floating around from the publisher (S. K. Kataria & Sons). Most "free PDF" sites are either: ❌ Packed with malware. ❌ Missing chapters (only up to Synchronous Motors, no Transients). ❌ Low-resolution scans that hurt your eyes.
So, here is your solid game plan to get the digital copy:
✅ 1. The Legal & Smart Route (Karma Points) Check your college library’s digital portal (like NDL, E-ShodhSindhu, or your institutional login). Many universities now have a digital copy for enrolled students.
✅ 2. The "Low Cost" Route The physical book costs ~₹400-500. The PDF isn't free, but you can buy the eBook legally on:
✅ 3. The "I need it tonight for the exam" Route
Use at your own risk. Some engineering forums and Telegram channels have scanned copies. Search tip: Use "Electrical Machines 2 J.B. Gupta filetype:pdf" on Google, but avoid clicking on sketchy ".xyz" or ".top" domains. Title: 📚 Where to Find Electrical Machines 2 by J
Pro Tip for studying: If you can't find the PDF, the table of contents is enough. Why? J.B. Gupta’s real value is in the solved numerical problems. Just photocopy the problem sets from a friend’s book – that’s what actually saves you in the semester exams.
Need a specific chapter? If you're stuck on "Synchronous Motor V-Curves" or "Hunting in Alternators", drop a comment. I (or someone here) can send you a photo of those 3-4 critical pages to get you through.
Good luck with your exams! 🔌📖
P.S. If someone DMs you a link, scan it with VirusTotal first. Stay safe.
