Preface to Electromagnetics for Electrical Machines eBook

The contents of this book are supported the syllabi of MTech courses on electrical machines in a number of the Indian universities and technical institutes.

it's basically designed to serve for a one-semester course at the postgraduate level for EE students. Its contents are mainly confined to the linear theory of electromagnetics.

Since this book lays more emphasis on concepts than on developing problem-solving skills, no numerical methods (viz. an iterative solution using relaxation techniques, finite difference methods, finite-element methods, the tactic of moment, etc.) are included.

the primary few introductory chapters of this book can also be employed by students of physics, electronics and communication engineering, also as those research scholars who are concerned with the issues involving electromagnetics.

The contents of this book are divided into the subsequent nine chapters. Chapter 1 is an introductory chapter that highlights the essence of theory and its correlation with the electrical machines.

Chapter 2 includes a review of Maxwell’s equations and scalar and vector potentials. It briefly describes the special cases resulting in the Laplace, Poisson’s, eddy current and wave equations.

Chapter 3 includes the individuality theorems, generalised Poynting theorem and a quick treatment of the Helmholtz theorem.

It also deals with the approximation theorems developed to reinforce the acceptability of approximate solutions of the sector equations obtained under certain specified boundary conditions.

Chapter 4 is dedicated to the answer of Laplace equation encountered within the design of electrical machines. It also introduces the Schwarz–Christoffel transformation and its applications and includes the determination of airgap permeance.

Chapter 5 outlines the solutions for eddy current equations. The skin effects in circular conductors, eddy currents in solid and laminated iron cores also are discussed.

Chapter 6 is dedicated to the analyses of electromagnetic fields in laminatedrotor induction machines. theory for anisotropic media and its application in laminated-rotor induction machines is briefly presented. the consequences of skewed rotor slots in laminated-rotor induction machines are discussed.

Chapter 7 presents three-dimensional field analyses for three-phase solid rotor induction machines. It also describes the top effects in solid rotor induction machines.

Field analysis for harmonic fields, in solid rotor induction machines thanks to tooth ripples, is additionally discussed. Chapter 8 includes the examples concerning the slot leakage inductance of rotating electrical machines, transformer leakage inductance and theory of hysteresis machines.

It presents the modelling of fields for a potentially new sort of single-phase induction motor with composite poles. It also includes the electromagnetic transients in solid-conducting plates.

An extension of this treatment may cause the study of electromagnetic transients in electrical machines. Chapter 9 briefly describes the common techniques employed in numerical analysis.

It also classifies all the cases described in Chapters 4 through 8 in accordance with the equations involved therein. This chapter also indicates the methods through which these equations are often solved to yield the specified results.

so as to reinforce the topic knowledge of the reader, this book includes some presentation/project problems at the top of every chapter. a number of the mathematical material,

for instance , evaluation of some lengthy integrals, is included within the appendices. one among these appendices includes a quick note on the Hilbert transform.

One appendix is fully dedicated to the present sheet simulation of a balanced three-phase armature winding carrying a balanced three-phase AC .

Throughout this book, standard symbols are used without defining them. Any nonstandard symbol is defined at the purpose it's first introduced; the meaning continues as long because it isn't redefined.
