Generalized Theory of Electrical Machines by P.S.Bimbhra is a book that covers the topics of electric machines in a generalized way, using linear transformations, matrix algebra, and state-space methods. The book aims to provide a unified and systematic treatment of various types of electrical machines, such as DC machines, polyphase synchronous machines, polyphase induction machines, single-phase motors, AC commutator motors, and transformers. The book also includes numerous solved examples, exercises, and objective questions to help students test their understanding and prepare for competitive exams.
The book is divided into six chapters: Elements of Generalized Theory, Linear Transformation in Machines, DC Machines, Polyphase Synchronous Machines, Polyphase Induction Machines, and Single-Phase Motors and AC Commutator Motors and Transformers. Each chapter begins with an introduction and ends with a summary of the main points. The book also has appendices that cover topics such as matrix algebra, state-space analysis, Park's transformation, and equivalent circuits of electrical machines.
Generalized Theory of Electrical Machines by P.S.Bimbhra is a comprehensive and rigorous book that can be used as a textbook for undergraduate and postgraduate courses in electrical engineering. It can also be used as a reference book by practicing engineers and researchers who are interested in the generalized theory of electrical machines.
One of the key concepts in the generalized theory of electrical machines is the linear transformation. A linear transformation is a mathematical operation that maps one set of variables to another set of variables, while preserving the linear relationships among them. For example, a linear transformation can be used to convert the three-phase voltages and currents of a polyphase machine to a single-phase equivalent circuit, or to convert the stator and rotor variables of a synchronous machine to a common reference frame.
Another important concept in the generalized theory of electrical machines is the state-space method. A state-space method is a technique that describes the dynamic behavior of a system using a set of state variables and a set of differential equations. The state variables are the minimum number of variables that can completely define the state of the system at any instant of time. The differential equations are derived from the physical laws and principles that govern the system. The state-space method can be used to analyze the transient and steady-state performance of electrical machines, as well as their stability and control.
