Electrical Machinery And Transformer Technology PDF Download

This text provides a clear presentation of the fundamental principles behind the operation of electrical machines and transformers with special emphasis on power electronics. Features: * Modern approach to power electronics and its applications provides a survey of solid-state devices and principles of electronic power conversion techniques for controlling AC and DC machines, topics neglected by standard machine texts. * Coverage also includes the conventional electromagnetic approach to both DC and AC motor control (Chapters 8 and 14). * Special attention is given to fractional, subfractional, and special purpose machines such as stepper motors, AC and DC servomotors, switched reluctance motors, and bruchless and linear induction motors, providing students with insights into technologies rapidly being introduced into automated manufacturing systems. * The SI system of units is used in the development of all theory in order to simplify the presentation, and parallel formulae in the English unit system are also given. * Aids to studying include chapter review questions, extensive problems, and Unit Conversion Tables.
