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.

This book highlights procedures utilized by the design departments of leading global manufacturers, offering readers essential insights into the electromagnetic and thermal design of rotating field (induction and synchronous) electric machines. Further, it details the physics of the key phenomena involved in the machines’ operation, conducts a thorough analysis and synthesis of polyphase windings, and presents the tools and methods used in the evaluation of winding performance. The book develops and solves the machines’ magnetic circuits, and determines their electromagnetic forces and torques. Special attention is paid to thermal problems in electrical machines, along with fluid flow computations. With a clear emphasis on the practical aspects of electric machine design and synthesis, the author applies his nearly 40 years of professional experience with electric machine manufacturers – both as an employee and consultant – to provide readers with the tools they need to determine fluid flow parameters and compute temperature distributions.

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.

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.
