Older editions (e.g., the 2005 or 2008 printings) contain unique problem sets not found in the latest revision. These are impossible to buy new but exist as scanned PDFs in digital archives.
A: Yes. Gupta’s coverage of voltage regulation methods (EMF, MMF, ASA, ZPF) and two-reaction theory is sufficient for GATE-level problems. For conceptual clarity, supplement with online notes.
Despite its age, Gupta’s book remains relevant for foundational coursework. Before a student can understand a variable-frequency drive, they must grasp the torque-speed curve of an induction motor. Before they can simulate a machine in ANSYS Maxwell or FEMM, they must understand the equivalent circuit. Gupta provides that foundational fluency. For universities with limited laboratory access, the solved performance problems serve as virtual experiments, allowing students to predict how terminal voltage, current, and efficiency change with load.
If you are an Electrical Engineering student, J.B. Gupta’s Theory and Performance of Electrical Machines is not just "another book"—it is a necessary tool. It transforms a difficult subject into a manageable one through sheer volume of practice.
Whether you buy the hard copy or find a digital version, make sure this book is on your desk during your semester prep. Good luck with your studies!
