Preface
Electrical engineering students are the target audience for this book on “Electrical Machines.”
Various Indian universities abroad offer courses in engineering (EE) and electrical and electronic engineering (EEE). Candidates applying for AMIE, IETE, GATE, and UPSC will also find this information useful.
Entrance exams for construction services and public services. We know that electrical energy and electrical machines have different uses. Electrical energy plays an important role in industry and many other fields of science and technology. For this reason,
In addition to electricity students, this book can help others. In addition to engineers, this book also caters to technicians and applied engineers.
Different universities teach “Electricity” under different names, such as Electricity-I Machinery, Electric Power-II, Direct Current Machines and Transformers, Electromagnetic Power Conversion Vehicles, Special Purpose Machines, etc. The same chapter covers all course topics. Therefore, the book contains the updated syllabus of all Indian and foreign universities. Generally, students perceive electrical machines as one of the most challenging subjects to comprehend, despite the abundance of books available on the topic. In light of this, the organization of these texts is systematic, placing a strong emphasis on key concepts.
Each chapter of the book includes essential, well-supported, and explanatory text. We have added numerous solved and unsolved case examples to different sections, allowing students to experiment with various question types. They successfully completed the test without encountering any issues. We constantly add in-class practice questions to all sections to enhance learning and understanding. Each chapter concludes with a wealth of material to review. The book includes quizzes, short answer questions, test questions, and unsolved examples for you to tackle. It is a comprehensive and all-encompassing resource.
The author does not claim to have conducted original research in preparation of the text. We used free research materials from well-known authors. However, the author asserts that he created the content and arranged the points in a specific order. He also acknowledges that the text’s language is complex. is simple and straightforward to understand.
Despite all efforts to eliminate errors, implementing them remains extremely challenging.
perfection. I hope this book will be useful to users (students, teachers, and professionals). Any errors reported by students, teachers, and book users will be greatly appreciated.

Using electrical energy is useful due to its low cost, ease of transmission, control, and efficiency. Natural resources such as water, coal, diesel, wind, and atomic energy typically provide electrical energy. These sources provide the first mechanical energy.
Using the appropriate machinery, we generate mechanical energy and then convert it into electrical energy. The industry transforms electrical energy into mechanical, heat, and light forms of energy. The industry has widely embraced electric drives due to their inherent benefits. An electrical system requires energy conversion devices at both ends. Electromechanical energy conversion devices convert mechanical energy to electricity and vice versa.
Magnetic circuits are essential to the operation of all electrical machines, including DC machines, transformers, synchronous machines, and induction motors. A magnetic circuit refers to the closed passage of magnetic lines of force. All electrical equipment, for instance, operates in this manner.
Magnetic circuits create magnetism that powers various devices such as transformers, generators, and motors. We must carefully build magnetic circuits for these devices to achieve the desired features.
This chapter covers the principles of magnetic circuits and their applications as energy converters.
