Analytic solutions of magnetic field problems in slotless permanent magnet machines

Yuriy N. Zhilichev

The Grinberg method is used to derive general 2D and 3D analytical solutions of the magnetic field problem in the slotless permanent magnet machines. The machines with the…

On the optimisation of discretising steps in the space and time domains along with over‐relaxation parameter in the finite difference solution of the transient heat‐flow equation

J. Akhtar

Optimisation of the discretising steps in the space and time domains has been studied for the evaluation of corresponding optimum value of over‐relaxation parameter in the…

Feedforward indirect vector control of a matrix converter‐fed induction motor drive

Sedat Sünter, Jon C. Clare

This paper describes the development of closed loop control techniques for matrix converter fed induction motor drives. A prototype drive rated at 2.5kW is used to demonstrate…

Path integral analysis for Gaussian beam propagation over non‐penetrable obstacles

C.S. Antonopoulos, Em.E. Kriezis, E.E. Kriezis

The path integral analysis has been used to examine the propagation of a Gaussian beam in two cases. First in free space and second in a space with a non‐penetrable obstacle…

Determination of the distribution function of Preisach’s model using centred cycles

Y. Bernard, E. Mendes, Z. Ren

A new method for the determination of the classical Preisach’s model distribution function is developed. The proposed method determines numerically the distribution function from…

Adaptive harmonic estimation for power system protection

T.I. Haweel

Many power system protection problems necessitate the measurement and track of the underlying current/voltage phasors. Adaptive LMS spectrum analyzers provide an ideal solution to…

New directions in computational modelling

Bill Trowbridge

Introduction to three panel presentations on possible future trends in computational electromagnetics held during the Compumag Conference at Sapporo, Japan in November 1999. The…

Immersive projection technology and wearable computers

Michitaka Hirose

In this paper, two recent VR technology topics are introduced. First, three keywords; (intuitive interaction, presence, multi‐sensory) which characterize VR technology are…

Modeling future automobiles: the role of industry and government

Larry Turner, Robert Larsen, Michael Duoba, Scott McBroom, Ashok Nedungadi, Keith Wipke

The Partnership for a New Generation of Vehicles (PNGV) is a joint project of the “big three” US automakers and seven US government agencies. The goal of the partnership is to…

Electromagnetism and academic training of electrical engineers

Lauri Kettunen

In this paper an attempt is made to examine the status and the role of the basic courses of electromagnetism in academic training of electrical engineers. The subject is viewed…
