It starts off with part one, which is DC Machines. It contains various subtopics such as Magnetic Circuits and Induction, Principles of Electromechanical Energy Conversion, Basic Concepts of Rotating Electrical Machines, Construction of DC Machines, Armature Reaction and Commutation in DC Machines, Operating Characteristics and Application of DC Generators, Parallel Operation of DC Generators, Operating Characteristics and Applications of DC Motors, Speed Control, Starting and Braking of DC Motors, Losses, Testing and Maintenance of DC Machines, Special Types of DC Machines, Thermistor Control of Electric Motors, and Objective Type Questions. The second part has the heading Polyphase Circuits. This topic consists of two sub sections named Polyphase Circuits and Objective Type Questions with Answers. The third part is named AC Machines. This section also contains various sub topics such as Transformers, Transformers (Continued), Synchronous Generators or Alternators, Rotating Magnetic Fields, Synchronous Motors, Parallel Operation of Alternators, Construction, Theory and Operation of Polyphase Induction Motors, Starting, Speed Control and Braking of Polyphase Induction Motors, Special Induction and Polyphase Commutator Machines, Fractional Kilowatt Motors, Synchronous Converters, Rectifiers, and Objective Type Questions with Answers. After that the index has been provided so that students may look up any term, word, or definition if deemed doubtful. aTable of Contents: Part-I: DC Machines Magnetic Circuits and Induction Principles of Electromechanical Energy Conversion Basic Concepts of Rotating Electrical Machines Construction of DC Machines Armature Reaction and Commutation in DC Machines Operating Characteristics and Application of DC Generators Parallel Operation of DC Generators Operating Characteristics and Applications of DC Motors Speed Control, Starting and Braking of DC Motors Losses, Testing and Maintenance of DC Machines Special Types of DC Machines Thyristor Control of Electric Motors Objective Type Questions Part-II: Polyphase Circuits Polyphase Circuits Objective Questions with Answers Part-III: AC Machines Transformers Transformers (Continued) Synchronous Generators or Alternators Rotating Magnetic Fields Synchronous Motors Parallel Operation of Alternators Construction, Theory and Operation of Polyphase Induction Motors Starting, Speed Control and Braking of Polyphase Induction Motors Special Induction and Polyphase Commutator Machines Fractional Kilowatt Motors Synchronous Converters Rectifiers Objective Questions with Answers Index aElectrical 2ddccDB 00102ddc4070aBSDUbBSDUcGENd2018-07-16g450.00l0o621.310 42 GUPpDB0046r2020-02-12 00:00:00v450.00w2018-07-16yDB
