Description
Excerpt from Direct-Current Machinery: A Text-Book on the Theory and Performance of Generators and Motors
Although but few graduates in electrical engineering ever have occasion to design a generator or a motor, the majority of them, at some time in their careers, will be called upon to operate or test such machines, or to pass upon their suitability for a particular service. The greater part of this book is therefore devoted to the performance, application, and testing of the various types of direct-current generators and motors.
The graphical method, given in Chapters VI and VII, for determining the performance characteristics of generators and motors, was developed by the author several years ago, with the assistance of Mr. H. R. West. This method, although in its simple form only approximate, brings out in a readily understood manner, the dependence of the performance of the machine upon the nature of its electric and magnetic circuits.
In the chapter on Commutation the attempt has been made to treat this subject in an understandable, and yet rigorous, manner. The nature of the effects produced by the various factors involved.
