ELECTRICAL MACHINE DESIGN
1.1 Principles of Design
Electrical machines play a vital role on domestic and industrial fronts. Hence, it is essential that students of
electrical engineering has a strong grounding in electrical machines.
Conventional courses in electrical machines are not adequate for the purpose of understanding as they throw light on the construction,
principle, characteristics, and testing.
A deeper understanding is possible only when they study the design aspects and their influence on the performance of the machines. It is thus necessary to have a course on electrical machine design, suitable for study by undergraduate students of electrical engineering.
This book is designed to meet the needs of a textbook for a course in electrical machine design.
It gives a comprehensive design aspect of DC and AC machines with an appropriate introduction to basic design considerations and the magnetic circuits involved.
Introduction to the design and analysis of the machines using the finite element analysis is also included as one chapter, to enable the readers to have a much deeper understanding. A design process always involves a long iterative process and a designer is required to take decisions in conflicting situations.
The design procedure of all the machines is given as simple flowcharts for the reader to understand the iterative nature of design process.
In addition to the worked examples, most chapters include number of problems designed to test the grasp of the subject. The readers will also appreciate the pedagogical practices followed in this book.
This book is the outcome of the long experience of the authors in teaching electrical machines and allied courses. The authors have made a commendable effort to present the contents in a clear and lucid form.
