Download or read book Analysis of Synchronous Machines written by T.A. Lipo and published by CRC Press. This book was released on 2017-12-19 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of Synchronous Machines, Second Edition is a thoroughly modern treatment of an old subject. Courses generally teach about synchronous machines by introducing the steady-state per phase equivalent circuit without a clear, thorough presentation of the source of this circuit representation, which is a crucial aspect. Taking a different approach, this book provides a deeper understanding of complex electromechanical drives. Focusing on the terminal rather than on the internal characteristics of machines, the book begins with the general concept of winding functions, describing the placement of any practical winding in the slots of the machine. This representation enables readers to clearly understand the calculation of all relevant self- and mutual inductances of the machine. It also helps them to more easily conceptualize the machine in a rotating system of coordinates, at which point they can clearly understand the origin of this important representation of the machine. Provides numerical examples Addresses Park’s equations starting from winding functions Describes operation of a synchronous machine as an LCI motor drive Presents synchronous machine transient simulation, as well as voltage regulation Applying his experience from more than 30 years of teaching the subject at the University of Wisconsin, author T.A. Lipo presents the solution of the circuit both in classical form using phasor representation and also by introducing an approach that applies MathCAD®, which greatly simplifies and expands the average student’s problem-solving capability. The remainder of the text describes how to deal with various types of transients—such as constant speed transients—as well as unbalanced operation and faults and small signal modeling for transient stability and dynamic stability. Finally, the author addresses large signal modeling using MATLAB®/Simulink®, for complete solution of the non-linear equations of the salient pole synchronous machine. A valuable tool for learning, this updated edition offers thoroughly revised content, adding new detail and better-quality figures.

Download or read book Advancements in Electric Machines written by J. F. Gieras and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, electrical machines are classi?ed into d. c. commutator (brushed) machines, induction (asynchronous) machines and synchronous machines. These three types of electrical machines are still regarded in many academic curricula as fundamental types, despite that d. c. brushed machines (except small machines) have been gradually abandoned and PM brushless machines (PMBM) and switched reluctance machines (SRM) have been in mass p- duction and use for at least two decades. Recently, new topologies of high torque density motors, high speed motors, integrated motor drives and special motors have been developed. Progress in electric machines technology is stimulated by new materials, new areas of applications, impact of power electronics, need for energy saving and new technological challenges. The development of electric machines in the next few years will mostly be stimulated by computer hardware, residential and public applications and transportation systems (land, sea and air). At many Universities teaching and research strategy oriented towards el- trical machinery is not up to date and has not been changed in some co- tries almost since the end of the WWII. In spite of many excellent academic research achievements, the academia–industry collaboration and technology transfer are underestimated or, quite often, neglected. Underestimation of the role of industry, unfamiliarity with new trends and restraint from technology transfer results, with time, in lack of external ?nancial support and drastic - cline in the number of students interested in Power Electrical Engineering.

This book was released on 2007-05-03 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Abstract: The objective of this thesis comprises the analytic and strategic approach to develop new and international markets based on the specific interest for the medium-sized US software company Pixel Magic Imaging, Inc. (PMI). PMI was in its infancy in terms of going international . In other words, PMI had neither an organized and international marketing conception nor a regular business to foreign customers and markets so far. Aim and object of this project was analyzing marketing opportunities for their product portfolio within different international markets and to approach adequate marketing strategies. Therefore data of international markets must be collected, evaluated and analyzed to put these results in a strategic order. This thesis deals with the development of foreign markets and how market entry could be realized. It focuses on explaining ways how to get there. The aim of this thesis is to prove which strategies are possible and to explain them in a general approach. The market research and defining the appropriate strategies where focused on the company s product portfolio. The products are digital imaging software and equipment and are placed in the segment for professional photographers, photographic entrepreneurs and retail outlets. The scope of duties in this thesis consisted in gathering data and compiling reports for international sales opportunities in so far unknown international markets. The study combines the theoretical approach with the know-how of working expierence and expatiated the methodology of international marketing research, designing of an international marketing concept and the implementation of market strategies in describing the theoretical disciplines and to implement these results into the company s strategy focus and product portfolio. This thesis benefits from the empirical data gained and its success based on an intensive exchange of ideas from theory and practical work experience.

Available in PDF, EPUB and Kindle. Book excerpt: Electrical drives convert in a controlled manner, electrical energy into mechanical energy. Electrical drives comprise an electrical machine, i.e. an electro-mechanical energy converter, a power electronic converter, i.e. an electrical-to-electrical converter, and a controller/communication unit. Today, electrical drives are used as propulsion systems in high-speed trains, elevators, escalators, electric ships, electric forklift trucks and electric vehicles. Advanced control algorithms (mostly digitally implemented) allow torque control over a high-bandwidth. Hence, precise motion control can be achieved. Examples are drives in robots, pick-and-place machines, factory automation hardware, etc. Most drives can operate in motoring and generating mode. Wind turbines use electrical drives to convert wind energy into electrical energy. More and more, variable speed drives are used to save energy for example, in air-conditioning units, compressors, blowers, pumps and home appliances. Key to ensure stable operation of a drive in the aforementioned applications are torque control algorithms. In Advanced Electrical Drives, a unique approach is followed to derive model based torque controllers for all types of Lorentz force machines, i.e. DC, synchronous and induction machines. The rotating transformer model forms the basis for this generalized modeling approach that ultimately leads to the development of universal field-oriented control algorithms. In case of switched reluctance machines, torque observers are proposed to implement direct torque algorithms. From a didactic viewpoint, tutorials are included at the end of each chapter. The reader is encouraged to execute these tutorials to familiarize him or herself with all aspects of drive technology. Hence, Advanced Electrical Drives encourages “learning by doing”. Furthermore, the experienced drive specialist may find the simulation tools useful to design high-performance controllers for all sorts of electrical drives.
