FUNDAMENTALS OF ELECTRICAL MACHINES has been revised thoroughly for readers, specially undergraduate students, to have a better and a clearer understanding of the subject. The following topics are new to the second edition: • Review of electric circuits. • Fleming’s rule and mutual inductance. • Exact and approximate equivalent circuit of a transformer. • Transformer losses. • Parallel connection of transformer with equal and unequal voltage ratios. • Transformer cooling and instrument transformers. • Power system symbols and per unit systems. • Demagnetizing and cross magnetizing components. • Details of armature voltage control method. • Speed control of dc motor by thyristor and diode. • Dynamic and regenerative braking of dc motor. • Approximate equivalent circuit and condition for maximum mechanical power of three-phase induction motor. • Classification of three-phase motor by properties. • Cogging, crawling and double squirrel cage motor. • Details of speed control of three-phase induction motor. • Stepper motor and its classification. Answers to all exercise problems are included at the end to encourage problem solving. An instructor’s manual is also available to academics upon request.
