Excerpt from The Induction Motor The writer wishes to take this opportunity to acknowledge his indebtedness to those who have preceded him in this field. Every work of an engineering nature is necessarily founded on that of others. An attempt to give original demonstrations of all of the elementary facts in relation to a subject, necessarily leads to a far less simple treatment than the frank use of older methods, when these methods are at least as clear as anything the author has to offer in their stead. In this regard, the present treatise is no exception. Particular mention should be made of the excellent works of Behrend, Boy de la Tour, and mcallister. In particular, the treatise of the last named author has been drawn upon for several simple and lucid demonstrations, notably for the proof of the circle diagram, and for one of the methods of treating the subject of single-phase motors. Credit has been given in the text for contributions of various writers. When this has not been done, the omission is due either to a lack of knowledge on the part of the author, of the work in question, or an uncertainty regarding the author to whom such credit should be given. Lack of time and space has caused the omission of much mate rial of historical interest. The same reason has caused the omission of the discussion of many ingenious devices designed to improve in various ways the performance of induction motors. Many of these relate to methods of improving the starting performance of induction motors, and present numerous points of theoretical and practical importance. In order to keep the size of the book within reasonable limits, it was thought best to limit the discussion almost entirely to devices in successful operation, and to those of recent introduction which seem most likely to be of permanent value. For the same reason, the treatment has been almost entirely confined to motors built in the United States. For much of the experimental work mentioned in the text the author is indebted to the careful work of Mr. H. L. Tanner, Instructor in the Department of Electrical Engineering of the University of Michigan, and to Mr. Stanley D. Livingstone, assistant in the same.
