ANALYSIS of ELECTRICAL MACHINES

An introductory chapter reviews the basic transformer and magnetically-coupled circuit theory concepts. Electrical circuit quantities are related to forces and torque of electrical origin, with applications to basic machines. Later chapters develop the theory of commutated and noncommutative machines. Park's equations are introduced in a natural way, showing their relationship to physical quantities, by first applying them to commutator machines. Because of the general availability of powerful computers, the approach to the analysis of transients in synchronous and induction machines has changed radically during the past few years. One of the central objectives of this text is to develop a firm understanding of the governing equations of these machines so that one can confidently apply these relationships to a broad variety of transient problems, including both linear and nonlinear effects, such as saturation and time-varying speed. However, a brief chapter is included to acquaint the reader with some of the traditional analytical approaches to transient analysis.
