Understand how speed, torque, voltage, and flux drive electric motion — a clear, practical guide to how motors work and how to control them for real-world results.
This edition explains the core ideas behind electric motors in a way that’s approachable for engineers, managers, students, and anyone curious about how electric devices convert power into motion. It threads together theory and hands-on application, showing how key quantities interact and how motion is produced and controlled in different motor types. The book emphasizes a unified view of motors and generators, sharing the idea that the same principles apply to both, with practical examples and explanations that connect voltage, current, speed, and torque.

Excerpt from Electric Motors: Their Action, Control and Application
The design and construction of electrical apparatus are well covered by existing literature, the books on such subjects being very numerous, and many of them are comprehensive as well as authoritative. On the other hand, the operation of electrical machinery has received comparatively little attention. This latter fact is anomalous when we consider that there are undoubtedly several hundred users for every designer or constructor of such apparatus, because each builder supplies a large number of customers. Hence the authors have endeavored to supply information that may be useful to those who operate or are interested in the operation of electric motors. Included among these are electrical engineers who install or run electric power plants, managers of manufacturing or other establishments in which electric drive is employed, as well as students and others who desire to acquaint themselves with the working of various kinds of electric motors and their application to useful purposes.
The subject is necessarily technical because it involves not only the mechanical factors speed and torque but also the electrical quantities voltage, current and flux. Moreover, any or all of these five fundamental quantities may, in fact usually do, vary and are affected by other factors or conditions. Hence the problems must be analyzed and solved with thoroughness to obtain results of real value and cannot be properly treated in a popular manner. Nevertheless care has been taken to introduce and explain each step or result as clearly as possible, and to illustrate each case, when feasible, by a specific numerical example based upon standard commercial motors.
The general method herein adopted is an outgrowth of the course of lectures on electric motors and their applications given in Columbia University since 1889. It is based upon the consideration of counter e.m.f. and its relation to impress...

Paperback. Etat : New. Print on Demand. This book delves into the fascinating world of electric motors, a technology that revolutionized industry in the late 19th and early 20th centuries. While the design and construction of these machines had been thoroughly documented, their operation remained a less explored area. The author recognizes the vital importance of understanding how motors function for the countless users who rely on them, from engineers running power plants to factory managers and even students eager to learn about these devices. The book approaches its subject with a technical rigor befitting the complex interplay of mechanical and electrical forces at work. However, the author carefully guides the reader through each step and concept, clarifying the relationship between speed, torque, voltage, current, and flux. The central concept of counter-electromotive force (CEMF) is explored in detail, revealing how it serves as a key indicator of motor action. This perspective allows the reader to see the commonalities between motors and generators, effectively merging two seemingly disparate technologies. Through this comprehensive exploration of electric motor operation, the author provides insights into the advantages and complexities of this critical technology, paving the way for a deeper understanding of electric motor control. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781330102060_0
