Présentation de l'éditeur

Library PREFACE IN presenting a new treatise on the induction motor, the writer is aware that he is entering a field in which there are already many excellent works. In this book, however, an attempt is made to present the subject from a somewhat new standpoint. The endeavor has been to produce a work that will have the greatest possible value for those who wish to inform themselves more fully regarding the theory of the induction motor than they can by studying the elementary text-books, but who at the same time do not care to go too deeply into the theoretical aspects of the question. The writers aim has, therefore, been to present so much of the theory as is necessary to understand the phenomena of the induction motor, so far as these phenomena relate to the design or operation of these machines. The student is assumed to have some knowledge of alternating currents, and to understand in a general way the operation of the alternator, the synchronous motor, the induction motor, etc. To this end, he is supposed to have read some of the several elementary texts dealing with these subjects. Throughout the book, an earnest endeavor has been made to present clearly the physical conception of the actions taking place. It is the writers belief that nine-tenths of the trouble experienced by many people in studying the action of electrical machinery comes from the lack of a clear idea of the elementary physical actions. An attempt is made to apply mathematical reasoning to the problem before this understanding is obtained, and the result is a mental haze, which is perhaps never dissipated. The reader is therefore strongly urged to study carefully the first two chapters, and make sure that they are fully understood, before going farther. Several subjects of the greatest practical importance have been only briefly mentioned, if treated at all, by previous writers. Som
