Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Direct-Current Machine Design: Being Instructions for the Design of Motors and Generators Branches of Science Involved in Dynamo De sign. - The following discussion of the design of dyna mos and motors will be confined to the consideration of direct-current machines. The design of a dynamo and motor relates to three essen tial parts: first, the armature carrying the Conductors in which the electric energy is generated or absorbed; second, the field magnet that produces the magnetic field or flux in which the armature revolves; and third, the various mechanical parts and arrangements necessary to carry out the electrical and magnetic actions. Thus, three great branches of science - electricity, magnetism, and mechanics - are involved. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Direct Current Motor and Generator Troubles written by Theodore S. G. and published by Forgotten Books. This book was released on 2017-10-22 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Direct-Current Motor and Generator Troubles: Operation and Repair The chief purpose of this book is to give the methods, which many years of experience have proved to be both simple and effective, for tracing and remedying direct current motor and generator troubles. In addition, the questions of the selec tion, operation, care and repair of direct current machinery are analyzed from the standpoint of the operator. The theories of why a motor or generator will run, as well as the problems and fundamentals underlying the design of direct current machinery, have been very completely given and expounded in numerous excellent books on the market. But it is our belief that there is a vast army of operators in the electrical world who are greatly interested in why the motor or generator will not run, and it is to supply informa tion on this topic that the present work has been written. Throughout, it is assumed that the operator is confronted with the question of selection of the best machine for his purpose; then with the question of the best operation of that machine and in case of troubles, with their tracing and effec tive remedying.

Book excerpt: Excerpt from Direct-and Alternating-Current Machine Design Being Instructions for the Design of Motors and Generators This volume is especially prepared for self-instruction in the art of designing direct- and alternating-current machinery. Care has been taken to remain strictly within the province of design; the reader being assumed to possess knowledge of the principles of electricity and magnetism, and to be familiar with the theory of operation of electrical machines. The designs are carried out according to methods developed in actual practice and are supplemented by data and dimensions of lines of machines actually built by several of the largest American and European companies. The book is divided into two parts: one treating the design of direct-current machines, and the other that of alternating-current machines; each part being followed by a list of questions which clearly bring out the important points to be remembered.

Download or read book Principles of Direct Current Machines Classic Reprint written by Alexander S. Langsdorf and published by Forgotten Books. This book was released on 2017-10-14 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Principles of Direct Current Machines This book has been prepared with the object of placing before junior and senior students of electrical engineering a reasonably complete treatment of the fundamental principles that underly the design and operation of all types of direct-current machinery. Instead of attempting to touch the high Spots in the whole field of direct-current engineering, attention has been coneen trated upon certain important features that are ordinarily dis missed with little more than passing mention, but which, in the Opinion of the author, are vital to a thorough grasp of the subject. For example, the book will be found to contain in Chapter III a full derivation of the rules covering armature windings (follow ing Professor Arnold), in addition to the usual description of typical windings; Chapters VI and VII include a considerable amount of new material concerning the Operating character istics of generators and motors, the treatment being largely graphical and including the use of three-dimensional diagrams for depicting the mutual relationships among all of the variables; and in Chapters VIII and IX there has been developed a much more extensive treatment of the important subject of commuta tion than has been heretofore, easily accessible to students of the type for whom the book is intended. In the selection and arrangement of the material dealing with commutation, care has been exercised to eliminate those minute details and exces sive refinements that are more likely to confuse than to clarify.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Direct-Current Machinery: A Text-Book on the Theory and Performance of Generators and Motors Although but few graduates in electrical engineering ever have occasion to design a generator or a motor, the majority of them, at some time in their careers, will be called upon to operate or test such machines, or to pass upon their suitability for a particular service. The greater part of this book is therefore devoted to the performance, application, and testing of the various types of direct-current generators and motors. The graphical method, given in Chapters VI and VII, for determining the performance characteristics of generators and motors, was developed by the author several years ago, with the assistance of Mr. H. R. West. This method, although in its simple form only approximate, brings out in a readily understood manner, the dependence of the performance of the machine upon the nature of its electric and magnetic circuits. In the chapter on Commutation the attempt has been made to treat this subject in an understandable, and yet rigorous, manner. The nature of the effects produced by the various factors involved.

Download or read book Handbook of Asynchronous Machines with Variable Speed written by Hubert Razik and published by John Wiley & Sons. This book was released on 2013-01-24 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook deals with the asynchronous machine in its close environment. It was born from a reflection on this electromagnetic converter whose integration in industrial environments takes a wide part. Previously this type of motor operated at fixed speed, from now on it has been integrated more and more in processes at variable speed. For this reason it seemed useful, or necessary, to write a handbook on the various aspects from the motor in itself, via the control and while finishing by the diagnosis aspect. Indeed, an asynchronous motor is used nowadays in industry where variation speed and reliability are necessary. We must know permanently for the sensitive systems, the state of process and to inform the operator of the appearance of any anomaly and its severity.

Download or read book Dynamos and Dynamo Design written by International Correspondence Schools and published by Forgotten Books. This book was released on 2017-10-11 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Dynamos and Dynamo Design: Direct Current Motors; Alternating Currents; Alternators; Alternating-Current Apparatus This volume contains an exceptionally clear and complete treatment of the design of direct-current dynamos and motors, together with a detailed discussion of the theory of alternating currents and descriptions of modern alternating current machinery. In presenting the subject of design, a full discussion of the parts of the machines is first taken up, followed by complete demonstrations of design problems. The subject of armature windings receives special attention. Numerous winding diagrams are provided, indicating clearly the relative positions of the coils, pole pieces, and commu tator bars. The text accords with the best modern practice. The theory of the action of motors, their connections and the many systems of speed control are set forth in a clear and comprehensive manner. The importance of a knowl edge of alternating currents in the electrical-engineering profession is steadily growing. Illustrations and the graphical methods of treatment have been freely used. The method of numbering the pages, cuts, articles, etc. Is such that each subject or part, when the subject is divided into two or more parts, is complete in itself; hence, in order to make the index intelligible, it was necessary to give each subject or part a number. This number is placed at the top of each page, on the headline, Opposite the page number; and to distinguish it from the page number it is preceded by the printer's section mark Consequently, a reference such as 16, page 26, will be readily found by looking along the inside edges of the headlines until 16 is found, and then through 16 until page 26 is found.
