This textbook provides comprehensive treatment on two major Electric Machines, viz., the DC Machines and the Transformers. Initial six chapters are allotted for DC Machines. The performance, design and modelling of DC Machines are thoroughly presented in these chapters in a lecture-type approach with many numerical examples to register the topics profoundly. Then the performance and design of transformers are presented in two separate chapters with number of worked examples of various higher order thinking standards. In almost all the technical institutions offering diploma and undergraduate degree programmes in Electrical Engineering, this textbook will appeal greatly to the students, because this forms the core subject. Engineers inquisitively preparing for competitive exams and higher studies entrance exams such as GATE will benefit in their preparations by studying from this textbook. 'Reflection Section' at different conceptual stages, will help the students to recollect the rudiments in full without further ambiguities. The concept check, multiple choice questions and exercise problems, will assist the students to attain the intended chapter outcomes.
