Preface
This book focuses on a very important and diverse fi eld of electric machines and
drives. The history of the electric machine, which is the keystone of electromechanical
energy conversion, dates back to the beginning of the nineteenth century. The names
of famous scientists, such as Michael Faraday, Joseph Henry or Nikola Tesla, are associ-
ated with the invention of the rotating electric machine. Electric drives have quickly
become an integral part of our everyday lives and we can hardly imagine our civiliza-
tion without them. Electric drives play a vital part in industry, transportation as well as
in modern households. If we counted the number of electric drives around every one of
us today, we would certainly be surprised how big the number is.
Since the invention of the fi rst electric machine, novel principles and designs have been
appearing and the properties and parameters of electric machines have been steadily
improving. The advent of power electronics and modern control circuitry at the end
of the twentieth century caused a revolution in the fi eld of electric drives. Nowadays,
when modern technologies are available and advanced materials and techniques com-
monly utilized, formerly inconceivable results can be achieved in the fi eld of modern
electric drives.
The twelve chapters of the book writt en by renowned authors, both academics and
practitioners, cover a large part of the fi eld of electric machines and drives. Various
types of electric machines, including three-phase and single-phase induction ma-
chines or doubly fed machines, are addressed. Most of the chapters focus on modern
control methods of induction-machine drives, such as vector and direct torque control.
Among others, the book addresses sensorless control techniques, modulation strate-
gies, parameter identifi cation, artifi cial intelligence, operation under harsh or failure
conditions, and modelling of electric or magnetic quantities in electric machines. Sev-
eral chapters give an insight into the problem of minimizing losses in electric ma-
chines and increasing the overall energy effi ciency of electric drives, which is currently
viewed as a priority.
I would like to express my gratitude to all the authors for their contributions, in which
they shared their valuable experience and knowledge with the readers. It was their im-
mense involvement that enabled the publication of this book. I would also like to thank
the InTech staff for their great eff ort and support in preparation of the book. I hope it

will benefi t the fi eld of electric machines and drives, provide the readers with a new
point of view on this interesting branch of electrical engineering and possibly initiate
many inventions and innovations in the future.
