Fundamentals of Electrical Drives [Paperback]

The purpose of this book is to familiarize the reader with all aspects of electrical drives. It contains a comprehensive user-friendly introductory text.

Electrical drives consist of a number of components, the electrical machine, converter and controller, all of which are discussed at various levels. A brief r?esum?e of magnetic and electrical circuit principles is given in chapter 1 together with a set of generic building modules which are used throughout this book to represent dynamic models. Chapter 2 is designed to familiarize the reader with the process of building a dynamic model of a coil with the aid of generic modules. This part of the text also contains an introduction on phasors as required for steady state analysis. The approach taken in this and the following chapters is to present a physical model, which is then represented by a symbolic model with the relevant equation set. A generic model is then presented which forms the basis for a set of build and play simulations set out in various steps in the tutorial at the end of the chapter. Chapter 3 introduces a single phase ideal transformer (ITF) which forms the basis of a generic transformer model with leakage and magnetizing inductance. A phasor analysis is given to familiarize the reader with the steady state model. The build and play tutorials at the end of the chapter give the reader the opportunity to build and analyse the transformer model under varying conditions. It is emphasized that the use of these build and play is an essential component of the learning process throughout this book. Chapter 4 deals with star and delta connected three phase systems and introduces the generic modules required to model such systems. The space vector type representation is also introduced in this part of the text. A set of build and play tutorials are given which reinforce the concepts introduced in this chapter. Chapter 5 deals with the concepts of real and reactive power l�
