Excerpt from Continuous-Current Dynamos and Motors: Their Theory, Design and Testing; With Sections on Indicator Diagrams, Properties of Saturated Steam, Belting Calculations, Etc., Etc.; An Elementary Treatise for Students
IN placing this work before the public it is not claimed that any new theory of the action of direct current dynamos and motors has been evolved. Standard authors have been freely consulted, but not copied. It is assumed that the student has a general knowledge of electricity and is conversant with the names of the different parts of the machines. No particular machine has been described, the work be ing a general consideration of the laws governing the design of direct-current dynamos and motors.
The first four chapters consist of a brief review of the electrical units and the general principles of the machines, and may be considered as an introduction to the subsequent portions. The higher branches of mathematics have been avoided and a knowledge only of algebra and the elements of geometry assumed.
It is hoped the work will prove of value to the student of electricity and to those called upon to de sign electrical machines who have not had the benefit of a thorough training in the science of electricity.
