Excerpt from Electrical Engineering Papers, 1919: A Collection of the Author's More Important Engineering Papers Presented Before Various Technical Societies and Published in Engineering Journals and Alsewhere From Time to Time
It is necessary to understand the characteristics of the poly phase motor in order to consider properly its application to the different classes of work to be met with in practice. These characteristics can be presented in the most intelligible manner by means of curves, which represent the relations between the speed, torque or turning effort, horse power expended and developed, amperes, etc. The speed-torque curve, which represents the speed in terms of the torque, is the most important one, as upon this depends the adaptability of the motor to the various kinds of work. The starting conditions also depend upon the speed-torque characteristics. The other curves that are of importance in prac tice are the current, efficiency and power factor. As these are dependent, to some extent, upon the speed-torque curve, this will be considered first. Before treating of its characteristics a short description of the motor itself will be given.

Paperback. Zustand: New. Print on Demand. In the early days of electrical engineering, Benjamin G. Lamme was an influential figure who greatly contributed to the development of electrical machinery. This compilation of his works provides a comprehensive overview of various aspects of electrical engineering, including the analysis of the polyphase induction motor's characteristics. The polyphase motor is examined in depth, going over its construction, winding, and operation. Diagrams illustrate its speed-torque curves and other essential characteristics. The book also delves into speed variation of these motors, discussing methods such as varying the number of poles, alternations, or using motors in tandem. It explores the relationship between applied voltage, current, and power factor, emphasizing the importance of maintaining high power factors for efficient system operation. Furthermore, the text delves into the design considerations for minimizing magnetic leakage in motors, leading to improved power factors and higher pulling-out torques. Overall, this book offers a detailed exploration of polyphase motors, their operation, and control methods, making it a valuable resource for electrical engineers, students, and anyone interested in the history and fundamentals of electrical machinery. 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. Bestandsnummer des Verkäufers 9781330348420_0
