Electric Machines

0.0

Designed for the first course on Electric Machines undertaken by the students of Electrical, Electronics, adn Instrumentation Engineering, teh book provides an excellent foundation to the theory of electromechanical devices with specific emphasis on rotating electric machines. It continues to lay emphasis on the fundamentals, physical concepts adn systematic development of circuit model equivalenets of both transformers and machines. Features Enhanced coverage of permanent magnet materials and their applilcations. New material on voltage and current transformers, audio frequency and grounding transformer { Chapter 3}. Discussions on induction motors, classes of squirrel cage motors, adn inverted induction machine have been expanded {Chapter9}. MATLAB based solved examples and exercises, including design of armature winding using MATLAB.
