Electrical machines are almost entirely used in producing electricity, and there are very few electricity-producing processes where rotating machines are not used. In such processes, at least auxiliary motors are usually needed. In distributed energy systems, new machine types play a considerable role: for instance, the era of permanent magnet machines has now commenced. About half of all electricity produced globally is used in electric motors, and the share of accurately controlled motor drives applications is increasing. Electrical drives provide probably the best control properties for a wide variety of processes. The torque of an electric motor may be controlled accurately, and the efficiencies of the power electronic and electromechanical conversion processes are high. What is most important is that a controlled electric motor drive may save considerable amounts of energy. In the future, electric drives will probably play an important role also in the traction of cars and working machines. Because of the large energy flows, electric drives have a significant impact on the environment. If drives are poorly designed or used inefficiently, we burden our environment in vain. Environmental threats give electrical engineers a good reason for designing new and efficient electric drives. Finland has a strong tradition in electric motors and drives. Lappeenranta University of Technology and Helsinki University of Technology have found it necessary to maintain and expand the instruction given in electric machines. The objective of this book is to provide students in electrical engineering with an adequate basic knowledge of rotating electric machines, for an understanding of the operating principles of these machines as well as developing elementary skills in machine design. However, due to the limitations of this material, it is not possible to include all the information required in electric machine design in a single book, yet this material may serve as a manual for a machine designer in the early stages of his or her career. The bibliographies at the end of chapters are intended as sources of references and recommended background reading. The Finnish tradition of electrical machine design is emphasized in this textbook by the important co-authorship of Professor Tapani Jokinen, who has spent decades in developing the Finnish machine design profession. An important view of electrical machine design is provided by Professor Val´eria Hrabovcov´a from Slovak Republic, which also has a strong industrial tradition. We express our gratitude to the following persons, who have kindly provided material for this book: Dr Jorma Haataja (LUT), Dr Tanja Hedberg (ITT Water and Wastewater AB), Mr Jari J¨appinen (ABB), Ms Hanne Jussila (LUT), Dr Panu Kurronen (The Switch Oy), Dr Janne Nerg (LUT), Dr Markku Niemel¨a (ABB), Dr Asko Parviainen (AXCO Motors Oy), xiv Preface Mr Marko Rilla (LUT), Dr Pia Salminen (LUT), Mr Ville Sihvo and numerous other colleagues.

Die Induktionsmaschine ist in ihrem Aufbau die einfachste elektrische Maschine. In der Ausführung mit Kurzschlußkäfig besitzt sie nur eine unter Spannung stehende Wicklung und stellt damit eine äußerst betriebssichere Maschine dar. Daher hat der Induktionsmotor einen außerordentlich großen Anwendungsbereich erobert. Zur Zeit beherrscht er das Gebiet der nicht regel baren Antriebe sowie der Antriebe mit geringen ~prüchen an die Regelbarkeit. Im Bestreben, den Anwendungsbereich der Induktionsmaschine zu erweitern, wurden die Eigenschaften der Maschine im Laufe der Zeit sowohl theoretisch als auch praktisch einer gründlichen Untersuchung unterzogen. Während das grund sätzliche Verhalten der Maschine bereits vor etwa 20 Jahren erforscht wurde und seinen Niederschlag in dem bekannten Buch von RICHTER gefunden hat, geht die Entwicklung der letzten Zeit in der Richtung der Verbesserung des Anlaufes, der Drehzahlregelung und der Verminderung der Zusatzverluste. Der Leistungsbereich der Maschine ist nach beiden Richtungen hin erweitert worden, wodurch dem Berechnungsingenieur neue Probleme gestellt wurden. Bei den großen Motoren sind dies: die mechanischen Kräfte und die Erwärmung sowohl im stationären als auch im Übergangszustand. Bei den kleinsten Motoren, die als Einphasenmotoren ausgeführt werden, steht die Beherrschung des Anlaufes im Brennpunkt der Entwicklung. Alle neueren Entwicklungsarbeiten sind zusammen mit den bereits bekannten und klassisch gewordenen Arbeiten im vorliegenden Werk gesammelt. Es gibt damit den heutigen Stand unserer Kenntnis über die Induktionsmaschinen wieder. Auch die langjährigen eigenen praktischen Erfahrungen des Verfassers in der Berechnung der Induktionsmaschinen sind hier berücksichtigt.

Die rationelle Energieverwendung im Bereich wärmetechnischer Systeme hat im mittel europäischen Raum einen hohen Stellenwert, da bei der überwiegenden Anzahl der Haus halte und Gewerbebetriebe der Energieverbrauch zur Wärmeerzeugung den größten An teil am Gesamtenergieverbrauch hat. Das Ziel des vorliegenden Bandes ist es, dem Leser die Vorgehensweise 'zur Beurteilung wärmetechnischer Systeme und energiesparender Maßnahmen zu vermitteln. Schwerpunktmäßig werden die Heiz- und Raumlufttechnik im Umfeld des Menschen behandelt, während das Gebiet der Prozeßwärme für die indu strielle Anwendung aus Gründen des Umfanges nur ansatzweise erörtert werden konnte. Der Anspruch dieses Buches liegt auf einer Ebene, welche bewußt nicht die Einzellösung hervorhebt, da sich das Optimum eines Gesamtsystems noch längst nicht einstellen muß, wenn die Teilsysteme optimiert sind. Das Verständnis der Verzahntheit des vorliegenden Gebietes mit anderen Fachgebieten ist deshalb eine wesentliche Voraussetzung für ko ordinierte Maßnahmen zur rationellen Energieverwendung. Diesem Umstand wird durch zahlreiche qualitative Systembetrachtungen und Zahlenbeispiele Rechnung getragen. Im ersten Abschnitt werden die speziellen Grundlagen der Heiz- und Raumlufttechnik be handelt. Dazu zählen Kenntnisse über technische Funktionsabläufe und die Behaglich keitsanforderungen des Menschen, zu deren Aufrechterhaltung diese Anlagen gebaut werden. Anlagentechnische Maßnahmen zur Energieeinsparung müssen sich immer an der Erfüllung der Behaglichkeitsanforderungen messen lassen. Weiterhin gehört es auch zu einer wirkungsvollen Energieberatung, Maßnahmen an gebäudetechnischen Anlagen als Teilmaßnahme am Gesamtsystem Gebäude zu verstehen, weil durch den Umfang der Systemverbesserung (energetisch-ökonomisch) letztlich die Rangfolge der durchzuführen den Maßnahmen bestimmt wird.

As engineering processes are automated and manpower is reduced, condition monitoring of engineering plants has increased in importance. This is a first edition of this book, written by Taver & Penman was published in 1987. The economics of industry has now changed, as a result of the privatization and deregulation of the energy industry, placing far more emphasis on the importance of the reliable operation of a plant, throughout the whole life-cycle, regardless of first cost. The availability of advanced electronics and software in powerful instrumentation, computers and Digital Signal Processors (DSP) has simplified our ability to instrument and analyze machinery. As a result condition monitoring is now being applied to a wider range of systems, from fault-tolerant drives of a few hundred Watts in the aerospace industry, to machinery of a few hundred Megawatts in major capital plants.In this new book the original authors have been joined by Li Ran an expert in power electronics and control, and Sedding, an expert in the monitoring of electrical insulation systems. The first edition has been revised and expanded merging the authors' own experience with that of machine analysts to bring it up-to-date.
