Download E-books Ölhydraulik: Handbuch für die hydrostatische Leistungsübertragung in der Fluidtechnik (VDI-Buch) (German Edition) PDF

By Dietmar Findeisen

Dieses umfassende Nachschlagewerk der Ölhydraulik für Geräteentwickler wie für projektierende Ingenieure von Maschinen und Anlagen liegt in aktueller, erweiterter Auflage wieder vor. Das hydrostatische Wirkprinzip wird erläutert, dessen Umsetzung in hydrostatischen Antrieben und Steuerungen beschrieben. Eine systematische Eingliederung in die Getriebetechnik erleichtert die Bewertung der hydrostatischen Lösung mit Leistungsübertragungen anderer Energiearten erleichtert. Aus einem breiten industriellen Anwendungsfeld werden cellular und stationäre hydraulische Anlagen vorgestellt, die zur Lösung gleichmäßig und ungleichmäßig übersetzender Bewegungsaufgaben eingesetzt werden. Komponenten für einen zuverlässigen Betrieb werden zur methodischen Auswahl für hydraulische Anlagen nach Aufgaben geordnet. Anhand einer Vielzahl detaillierter Schnittbilder werden hydraulische Geräte nach Funktion und Aufbau für die Praxis erläutert. Zu deren anforderungsgerechter Auslegung werden Grundlagen der Strömungsmechanik und angrenzender Disziplinen wie Konstruktionslehre, Getriebetechnik und Leittechnik (Steuerungs- und Regelungstechnik) dargestellt.

Neu aufgenommen in der fünften Auflage wurden umweltverträgliche Fluide, die Kfz-Hydraulik, sowie Simulationen. Die Abschnitte zu Mechatronik und Elektrohydraulik wurde ausgeweitet.

Download E-books The Field Orientation Principle in Control of Induction Motors (Power Electronics and Power Systems) PDF

By Andrzej Trzynadlowski

The sector Orientation precept was once fIrst formulated via Haase, in 1968, and Blaschke, in 1970. at the moment, their rules appeared impractical end result of the inadequate technique of implementation. even though, within the early eighties, technological advances in static strength converters and microprocessor-based regulate structures made the high-performance a. c. force structures totally possible. in view that then, 1000's of papers facing a number of features of the sector Orientation precept have seemed each year within the technical literature, and diverse advertisement high-performance a. c. drives in accordance with this precept were constructed. The time period "vector regulate" is usually used in regards to those platforms. at the present time, it kind of feels convinced that the majority d. c. commercial drives could be ousted within the foreseeable destiny, to be, in significant half, outmoded by means of a. c. force platforms with vector managed induction automobiles. This transition has already been happening in industries of constructed international locations. Vector managed a. c. drives were confirmed able to even greater dynamic functionality than d. c. force structures, due to larger allowable speeds and shorter time constants of a. c. vehicles. it may be pointed out that the sphere Orientation precept can be utilized on top of things not just of induction (asynchronous) cars, yet of every kind of synchronous cars in addition. Vector managed force platforms with the so­ known as brushless d. c. cars have discovered many functions in excessive­ functionality force structures, equivalent to computer instruments and business robots.

Download E-books Protection of Industrial Power Systems, Second Edition PDF

The security that is put in on an business strength approach might be subjected to more challenging stipulations than the safety on the other form of energy process. beginning with the various easy units that are hired and protecting the entire region of commercial energy method safeguard, this e-book goals to aid in attaining a radical realizing of the safety necessary.

important elements akin to the trendy cartridge fuse, different types of relays, and the position of the present transformer are coated and the generally used inverse definite-minimum time overcurrent relay, the speculation of the Merz-Price safeguard approach and the improvement of the high-impedance relay process are significantly tested. This re-creation has occur in keeping with the dramatic switch from using electro-magnetic relays to digital and micro-processor relays which determine in virtually all new installations. for this reason, even if the idea and utilization are a similar, the applying will be a lot greater as a result of the elevated variety and accuracy and the additional amenities supplied with the fashionable relays. This publication displays the switch and explains the technical merits.
