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.

Excerpt from Principles of Alternating Current Machinery The transformer is the simplest piece of alternating-current apparatus and logically perhaps should be considered first in discussing the principles of alternating-current machinery. Experience has shown, however, that students just beginning the subject grasp the principles of the alternator more readily than those of the transformer. For this reason the alternator is taken Up first. No attempt has been made to treat all types of alternating current machines, only the most important being considered. Certain types have been developed in considerable detail where such development seemed to bring out important principles, while other types have been considered only briefly or omitted altogether. No new methods have been used, but it is believed that bringing together material which has been much scattered and making it available for students is sufficient reason for the publication of the book. Mathematical and analytical treatment of the subject has been freely employed where such treatment offered any advantage. The symbolic notation has been used throughout the book.

Excerpt from 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 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.

Excerpt from Principles of Electrical Engineering This text is the outgrowth of experience in teaching the principles of electrical engineering to students Of electrical engineering at the Massachusetts Institute of Technology. It aims to provide a substantial first course in the subject by presenting rigorously, and at the same time in under standable form, the really basic principles upon which modern electrical engineering rests. In furtherance of this purpose many problems and examples from current engineer ing practice are introduced. The book is not, however, to be mistaken for a complete condensed treatise on the entire subject. It is strictly a first course on the principles, and its study Should be followed by detailed courses in direct-current and alternating-current machinery. Where ever applications of the principles are introduced, they are for the purpose of illustrating these principles and render ing them real and alive to the student.

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.

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.

Excerpt from Direct-Current Machinery: A Text-Book on the Theory and Performance of Generators and Motors The author knows of no text-book on direct-current machinery which gives a thorough treatment of the theory and performance of such machines, without at the same time going into the details of design to such an extent as to be confusing to the mind of the ordinary undergraduate student. It is with the desire to provide such a text that this book is offered to the teachers and students of Electrical Engineering. In the author's opinion, a course in the design of electric machinery is out of place in the undergraduate curriculum. A student of electrical engineering should, however, acquire a thorough knowledge of the theory of such machines and of the basic principles upon which their design depends. Only to this extent, therefore, is the matter of design gone into in this book. Those interested in the details of design are referred to such books as Arnold's Die Gleichstrommaschine or Langsdorf's Principles of Direct-current Machines. 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.

Excerpt from Electrical Machine Design: The Design and Specification of Direct and Alternating Current Machinery A study of design is of the utmost importance to all students, because only by such a study can a knowledge of the limitations of machines be acquired. The machines discussed are those which have become more or less standard, namely, direct-cur rent generators and motors, alternating current generators, syn chronons motors, polyphase induction motors, and transformers; other apparatus seldom offers an electrical problem that is not discussed under one or more of the above headings. The principle followed throughout the work is to build up the design for the given rating by the use of a few fundamental formulae and design constants, the meaning and limits of which are discussed thoroughly, and the same procedure has been followed for the several pieces of apparatus.
