This book describes in detail the construction and working principle of a variety of commercially available hysteresis machines. The last part of the book is devoted to a comprehensive study of an experimental hysteresis machine. The contents of this part derive entirely from the experimental and analytical work carried out by the author during his doctoral research at the University of Aston in the UK. The exhaustive range of tests and measurements, obtained by the use of uniquely devised transducers and techniques—many of these having been evolved for the first time—showcase numerous aspects of a hysteresis machine. These relate mainly to the measured waveforms of radial and peripheral flux density in the airgap and active part of the rotor as influenced by the hysteretic properties of the rotor material.

All hysteresis machines, are characterised by the use of a 'hard' or permanent-magnet material in the rotor of the machine in different forms whilst the stator may be similar to that of a 3-phase induction motor or comprise salient poles. The driving torque in the hysteresis machine is typically related to loss of power resulting from hysteresis in the active part of the rotor. A hysteresis motor which forms the mainstay of a variety of hysteresis machines is a synchronous motor, being self-starting with the developed torque remaining constant throughout. The present book, one of its kind covering the said subject matter, describes in detail the construction and working principle of a variety of commercially available hysteresis machines. The last part of the book is devoted to a comprehensive study of an experimental hysteresis machine. The contents of this part derive entirely from the experimental and analytical work carried out by the author during his doctoral research at the University of Aston in the UK. The exhaustive range of tests and measurements, obtained by the use of uniquely devised transducers and techniques, many of these having been evolved for the first time, showcase numerous aspects of a hysteresis machine, never before brought out anywhere. These relate mainly to the measured waveforms of radial and peripheral flux density in the airgap and active part of the rotor as influenced by the hysteretic properties of the rotor material.

This thesis describes an investigation of the steady-state power losses, with dynamic excitation, in ferromagnetic materials and the performance and analysis of induction, hysteresis and synchronous machines with particular reference to hysteresis and eddy-current effects. Representation of a hysteresis loop by an elliptical characteristic, as used extensively in this thesis, permits a ferromagnetic material to be represented by its complex permeability. Although this concept has been employed by several previous authors including Butler and Mang, and Miyairi and Kataoka, the application of the concept to include non-linearity and eddy-current effects and a field-theory approach to the analysis of rotating machine performance is novel as far as the author is aware. Consideration is also given to the representation of hysteresis by concentrated coils in the analysis of different types of rotating machines thus permitting the derivation of appropriate equivalent circuits.

This book aims to offer a thorough study and reference textbook on electrical machines and drives. The basic idea is to start from the pure electromagnetic principles to derive the equivalent circuits and steady-state equations of the most common electrical machines (in the first parts). Although the book mainly concentrates on rotating field machines, the first two chapters are devoted to transformers and DC commutator machines. The chapter on transformers is included as an introduction to induction and synchronous machines, their electromagnetics and equivalent circuits. Chapters three and four offer an in-depth study of induction and synchronous machines, respectively. Starting from their electromagnetics, steady-state equations and equivalent circuits are derived, from which their basic properties can be deduced. The second part discusses the main power-electronic supplies for electrical drives, for example rectifiers, choppers, cycloconverters and inverters. Much attention is paid to PWM techniques for inverters and the resulting harmonic content in the output waveform. In the third part, electrical drives are discussed, combining the traditional (rotating field and DC commutator) electrical machines treated in the first part and the power electronics of part two. Field orientation of induction and synchronous machines are discussed in detail, as well as direct torque control. In addition, also switched reluctance machines and stepping motors are discussed in the last chapters. Finally, part 4 is devoted to the dynamics of traditional electrical machines. Also for the dynamics of induction and synchronous machine drives, the electromagnetics are used as the starting point to derive the dynamic models. Throughout part 4, much attention is paid to the derivation of analytical models. But, of course, the basic dynamic properties and probable causes of instability of induction and synchronous machine drives are discussed in detail as well, with the derived models for stability in the small as starting point. In addition to the study of the stability in the small, a chapter is devoted to large-scale dynamics as well (e.g. sudden short-circuit of synchronous machines). The textbook is used as the course text for the Bachelor’s and Master’s programme in electrical and mechanical engineering at the Faculty of Engineering and Architecture of Ghent University. Parts 1 and 2 are taught in the basic course ’Fundamentals of Electric Drives’ in the third bachelor. Part 3 is used for the course ’Controlled Electrical Drives’ in the first master, while Part 4 is used in the specialised master on electrical energy.
