Graciano Goudreau
The importance of various electrical machines is well known in the various engineering fields. The book provides comprehensive coverage of the magnetic circuits, magnetic materials, single and three phase transformers and d.c. machines. The book is structured to cover the key aspects of the course Electrical Machines - I.
The book starts with the explanation of basics of magnetic circuits, concepts of self and mutual inductances and important magnetic materials. Then it explains the fundamentals of single phase transformers including the construction, phasor diagram, equivalent circuit, losses, efficiency, methods of cooling, parallel operation and autotransformer. The chapter on three phase transformer provides the detailed discussion of construction, connections, phasor groups, parallel operation, tap changing transformer and three winding transformer. The various testing methods of transformers are also incorporated in the book.
The book further explains the concept of electromechanical energy conversion including the discussion of singly and multiple excited systems. Then the book covers all the details of d.c. generators including construction, armature reaction, commutation, characteristics, parallel operation and applications. The book also includes the details of d.c. motors such as characteristics, types of starters, speed control methods, electric braking and permanent magnet d.c. motors. Finally, the book covers the various testing methods of d.c. machines including Swinburne's test, brake test, retardation test and Hopkinson's test.
The book uses plain, lucid language to explain each topic. The book provides the logical method of explaining the various complicated topics and stepwise methods to make the understanding easy. Each chapter is well supported with necessary illustrations, self-explanatory diagrams and variety of solved problems. All the chapters are arranged in a proper sequence that permits each topic to build upon earlier studies. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
After graduation, he started his career as Visiting Lecturer in Bharati Vidyapeeth's College of Engineering, Pune, and PVG's College of Engineering and Technology, Pune. Then he continued as a lecturer at Vishwakarma Institute of Technology (VIT), Pune.
While working in VIT, he introduced new concepts in teaching methods. He also introduced the concept of Quality Circle at the educational institute level. The Quality Circle, started by him at VIT, got recognition at the national level. While working in VIT, he conducted training programs in various industries like Bajaj Auto, Bharat Electronics, Cummins, etc. He developed many small models and projects in Electrical Department of VIT to teach engineering subjects concepts. At the same time, he published his first book on Feedback Control Systems which got an overwhelming response all over India.
After leaving VIT, he was Joint Director of Noble Institute of Computer Training, Pune. Due to his dedicated teaching and endless efforts, many students from this institute got admission to ranked U.S. universities with an assistantship.
After that, he started his coaching classes to impart thorough knowledge to the engineering students of various engineering subjects. Professor Bakshi simultaneously published many engineering books. The books written by him are recommended by multiple Indian and foreign universities in Electrical and Electronics Engineering. He has a total of 30 years of teaching and writing experience in the field of engineering.
The book is written for an undergraduate course on the Basic Electrical Engineering. It provides comprehensive explanation of theory and practice of electrical engineering. It elaborates various aspects of d.c. and a.c. circuit analysis, magnetic circuits, measuring instruments, single phase transformers and various electrical machines.
The book starts with the concepts of electric charge, current and potential difference. It explains Kirchhoff's laws, star-delta transformation, mesh analysis and node analysis. It also covers the application of various network theorems in analyzing d.c. circuits.
The book also includes the discussion of magnetic circuits, self and mutual inductances and magnetic hysteresis. The book further explains the details of single-phase transformers and various electrical machines such as d.c. machines, three phase and single-phase induction motors and synchronous machines. The brief introduction of power system is also incorporated in the book.
The book uses plain, lucid language to explain each topic. The book provides the logical method of explaining the various complicated topics and stepwise methods to make the understanding easy. All the chapters are arranged in a proper sequence that permits each topic to build upon earlier studies. The variety of solved examples is the feature of this book which helps to inculcate the knowledge of the basic electrical engineering in the students. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
