Electrical Machine Design by V. Rajini and V. S. Nagarajan is a comprehensive textbook published by Pearson Education (2018) that serves undergraduate and postgraduate electrical engineering students. The book is known for its flowchart-based approach, which simplifies complex design procedures for various electrical machines. Core Content & Chapter Breakdown
The textbook is structured into five primary units, moving from general theory to the specific design of major machine types:
Unit I: Basic Design Considerations: Covers fundamental principles, choice of electrical and magnetic loadings, thermal considerations, and types of conducting, magnetic, and insulating materials.
Unit II: Design of Magnetic Circuits: Focuses on calculating MMF of air gaps and teeth, iron losses (hysteresis and eddy current), and estimation of leakage reactance. electrical machine design v rajini pdf work
Unit III: Design of Transformers: Detailed steps for dimensioning the core, windings, and cooling tank, including window space factor and operating characteristics.
Unit IV: Design of Induction Motors: Includes stator and rotor design (squirrel cage and slip ring), calculation of magnetizing current, and short-circuit parameters.
Unit V: Design of Synchronous Machines: Covers main dimensions of salient pole machines, armature design, and rotor design for turbo-alternators. Key Features for Students Electrical Machine Design by V
Automated Design Tools: The text uniquely integrates MATLAB and C programs alongside Finite Element simulations using Motor Solve to provide perspectives on modern automated design.
Competitive Exam Prep: Includes multiple-choice questions (MCQs), worked-out examples, and review questions ranging from short to long-form problems.
Pedagogy: Readers have praised the book for its simple language and helpful images that clarify abstract concepts. Where to Access the Work Electrical Machine Design In daily life: Using a hairpin to fix
