Book Description
Excerpt from Continuous Current Dynamos and Motors: And Their Control, Being a Series of Articles Reprinted From the Practical Engineer The first portion of this volume, so far as the end of the treatment of windings for closed-coil armatures, appeared originally as a aeries of articles in The Practical Engineer, from the pen of another writer. I can thus claim no credit for the merits of this part, my own attempt to set forth the subject as instructively as possible being confined to the later pages. I have endeavoured to give a fairly complete account of the ways in which the principles previously dealt with are applied in the design and construction of the various forms of generators and motors, and to consider this in conjunction with the mechanical points involved. Perhaps the features in which the present volume differs chiefly from similar works on the subject is in the rather fuller treatment of electrical traction, so far as tramway motors and their gear are concerned, and in the discussion of the flux-speed-torque curves for motors excited by the different standard methods. The former is, I think, justified by the ever-increasing importance and extension of electric tramway systems, while the latter strike the mind more vividly than many figures or worded statements of the facts they indicate. I would invite the reader's attention to the words of Mr. Heaviside which terminate the introduction, and impress upon him the absolute necessity for taking actual figures and making for himself calculations and curves, as only in this way can a proper understanding of electrical design be possibly obtained. In conclusion, I must express my thanks and indebtedness to the various firms who have kindly placed information or illustrations at my disposal, to the various authors whose works I have extracted from or cited - in every case, I hope, with due acknowledgment, and to my late assistant Mr. H. Nutton, for much help in preparing the diagrams. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
