The fourth edition of Electric Machines, widely considered as one of the premier texts on the subject, marks the twenty-fifth anniversary of this book. It provides an excellent foundation to the theory of electromechanical devices with specific emphasis on rotating electric machines. This new edition continues to lay emphasis on the fundamentals, physical concepts and systematic development of circuit models and analysis of both transformers and machines.

The theory and applications of various machines are discussed in detail, aptly supported by numerous solved examples, practice questions and MATLAB examples that enhance problem-solving skills.

New to the third Edition :

• New chapter on Generalised Theory of Electric Machines
• Testing of DC Machines
• Parallel Operation of DC Generators
• Determination of Voltage Regulation of Alternator by MMF Method and ASA Method.
• Detailed discussion on Permanent Magnet DC Motors
• More tutorial-type solved problems on Synchronous Generator (Alternators) and Motor
• MATLAB-based additional solved examples and exercises at appropriate places throughout the book, including design of armature winding

From the reviewers :

“The language is simple and clear. It is an excellent undergraduate textbook.”
