This paper summarizes the core principles of alternating current (AC) machinery based on the textbook Electrical Machines-II by J.B. Gupta
. The text covers the theory, performance analysis, and practical applications of polyphase and single-phase machines. sk kataria & sons 1. Polyphase Induction Motors electrical machines 2 by j.b. gupta pdf
Induction motors are the workhorses of the industry due to their ruggedness and simplicity. Key topics include: Operating Principle : Based on the production of a rotating magnetic field (RMF) when a 3-phase supply is given to the stator. Performance Characteristics : Detailed analysis of torque-slip characteristics
, including starting torque, pull-out torque, and the effect of rotor resistance. Equivalent Circuit & Testing No-load and Blocked-rotor tests
to determine the parameters of the equivalent circuit and assess efficiency. : Methods for (Star-Delta, Autotransformer) and speed control (V/f control, pole changing). Malla Reddy College of Engineering and Technology 2. Synchronous Generators (Alternators)
These machines are the primary source of electrical power generation globally. biet.ac.in Construction : Differentiation between cylindrical rotor machines (high-speed) and salient pole machines (low-speed). Voltage Regulation : Methods to calculate regulation, such as the Synchronous Impedance (EMF) method MMF method Zero Power Factor (ZPF) method Parallel Operation : Conditions and procedures for synchronizing
alternators with an infinite bus, including load sharing and the effect of excitation. biet.ac.in 3. Synchronous Motors
Unlike induction motors, these machines run at a constant synchronous speed regardless of load. Pulchowk Campus V and Inverted V Curves : Analysis of how changing excitation affects the armature current and power factor. Applications : Primarily used for constant speed drives and as synchronous condensers for power factor correction. Malla Reddy College of Engineering and Technology 4.

Electrical Machines-II by J.B. Gupta is a widely recognized textbook in electrical engineering, published by S.K. Kataria & Sons. It specifically focuses on Alternating Current (AC) machinery, serving as a continuation of foundational electrical machine concepts. Core Focus and Objective
The primary goal of the text is to provide a detailed analysis of polyphase induction motors, synchronous generators (alternators), and synchronous motors. It bridges the gap between theoretical electromagnetic principles and practical industrial applications like power generation, electric traction, and industrial drives. Detailed Table of Contents By respecting intellectual property, you ensure that authors
The book is typically organized into five major units focusing on AC machines: Electrical Machines By Jb Gupta - sciphilconf.berkeley.edu
If you want a physical book but can't afford new, buy a used copy from platforms like BookChor or your senior batchmates. You can then scan specific chapters for personal use (Fair Use policy).
The book is famous for its theoretical rigor combined with numerous solved examples. Every chapter ends with a battery of multiple-choice questions (MCQs) and long-answer problems, making it a favorite for competitive exams like GATE, IES, and state engineering service exams.
In many remote areas or during online semesters (post-COVID), physical bookstores were closed. The PDF was the only way to continue learning.
