Theory and Performance of Electrical Machines by J.B. Gupta is a widely recognized textbook in electrical engineering, valued for its comprehensive coverage of both AC and DC machines. Published by S.K. Kataria & Sons

Gupta’s book is explicitly designed for self-study and examination preparation. Each chapter follows a predictable, effective pattern:

The title’s emphasis on “performance” is deliberate. Where many textbooks stop at equivalent circuit parameters, Gupta dedicates substantial space to how machines behave under real conditions.

Understanding magnetic flux, reluctance, and electromagnetic induction.

: Construction, EMF equation, armature reaction, commutation, and operating characteristics.
