From highly respected authors in this field, this book is the first to examine the close relationship between the physical phenomena of electromagnetism and the geometry of space and time. It draws on geometrical insights of the author's mathematical research to produce an outstanding work, which will be of interest to all graduate students and researchers in electromagnetic field theory.

Th spiral vector theory proposed and explained in this book aims to unify the steady state and transient state theories of AC circuits and machines. It can be used to analyze transient phenomena in AC motors and has led to new torque control methods for the control of DC motors.

The operation and analysis of different types of electrical machines and variable-speed drives is described in this book, using space-vector theory. The equations are arranged in forms that can be directly used for computation.

This practical introduction for those unfamiliar with servomotors and motion control covers power and drive electronics, mechatronics and control electronics, power semiconductor devices, microprocessors, controllers, sensors, magnetic materials, design methods and applications.

An introduction to recent developments in the application of wave-splitting methods to direct and inverse scattering of wave fields. The text is volume 44 in the MONOGRAPHS IN ELECTRICAL AND ELECTRONIC ENGINEERING SERIES and emphasizes time domain methods, although some applications to frequency domain problems are also included.

This text discusses numerous artificial intelligence applications to electrical machines and drives. The drives considered are: DC drives; induction motor drives; synchronous motor drives; switched reluctance motor drives; and sensorless drives.

The impact of optimization methods in electromagnetism has been much less than in mechanical engineering and particularly the solution of inverse problems in structural mechanics. This book addresses this omission: it will serve as a guide to the theory as well as the computer implementation of solutions. It is self-contained covering all the mathematical theory necessary.

This text covers the dynamics and control of induction motor drives. Continued advances are making possible the implementation of ac drive systems in place of dc However, disadvantageously, there is a degree of complexity in the ac drive control system, which this book seeks to explain.

Offers a discussion of on-line and off-line parameter estimation of smooth-air-gap and salient-pole electrical machines and their diagnosis and condition monitoring. This book presents a physical and mathematical analysis of the various parameter estimators and condition-monitoring methods.

An account of ultrasonic motors - a new type of electric motor which employs the piezo-electric effect to give the motive power (rather than electromagnetic interactions in conventional motors). One of the authors, Sashido, is the inventor of the ultrasonic motor.

A comprenehsive treatment of these devices: theory, construction, design, control and analysis, and applications. They are used in positioning systems (robotic assembly), chart recorders, etc.

The authors take a practical approach to the subject using many informative diagrams to explain the motor's working principles, constructional details, electronic controls, applications, and methods of manufacture.

Reluctance synchronous motors are attractive both for their line-start (constant speed) and for their variable speed (inverter-fed) applications. Ths book is the first comprehensive treatment of this emerging competitor in the electric drive market.

This monograph reviews various aspects of linear induction drives and motors: constructions; operation; applications; modern theory; design (including both rough estimation and computer aided methods); and testing.

The purpose of this book is to describe intelligent control and its use in power electronic systems, specifically AC motor drives and uninterruptable power supply (UPS) systems. The book covers both the fundamentals of the subject and its practical applications.

In recent years vector-controlled a.c. drives have taken over from more conventional d.c. drives. Applications are found everywhere including machine tools and robotics. This text examines sensorless vector-controlled drives and direct torque-controlled drives.

Discusses aspects of semiconductor devices, circuits and systems, ranging from recent developments in devices for VSLI circuits to simple analytical models. There is also coverage of testing and details of physical layout of chips.

A comprehensive and up-to-date reference book on modern electric vehicle technology, which covers the engineering philosophy, state-of-the-art technology, and commercialisation of electrical vehicles.

The SRM is unusual both for having salient teeth on rotor and stator, and for its complete dependence on its power electronic controls. It is however very versatile. The aim of this book is to help engineers understand, design and evaulate the properties and capabilities of the switched reluctance motor (SRM) and its control.

Designed to give the theoretical foundation of finite elements in electrical power engineering, - and showing how the equipment designer can benefit from finite element analysis - this text is divided into 3 parts; theory, modelling, and application of the finite element method.

Eddy currents appear in electromagnetic devices (e.g. the cores of transformers or rotors in electric motors) whenever a magnetic field varies through a conductor. Very often they are undesirable representing a power loss. The prediction of eddy currents is therefore of great practical importance. This book looks at numerical modelling methods for the prediction of eddy currents.

This book is a unique combination of theory and practice and gives a complete description ever written of the design and performance of modern brushless DC motors. This motor type is growing rapidly in importance in motion control, automation, computer equipment, automotive and aerospace actuation and high efficiency electrical drives.
