Excerpt from Continuous and Alternating Current Machinery: An Elementary Text-Book for Use in Technical Schools
At the present time the study of Electricity and Electrical Machinery occupies a very important place in the curricula of industrial schools, technical high schools and engineering schools. The application of electrical power is becoming so general that a knowledge of the simple principles and operating characteristics of the different types of electrical machinery is of great value to the man engaged in technical work of any kind.
This text was written especially for the use of students in technical high schools and similar institutions, but it is believed that it will be of value also for certain courses in engineering schools. Many of the students in engineering schools do not have the time for an exhaustive study of the subject of Electrical Machinery, but every engineering graduate should have some knowledge of the different kinds of generators and motors in every day use. To such non-electrical students the text should prove helpful.
In the preparation of this book the author has kept in mind the importance of simple, non-mathematical, explanations of the behavior of the various machines. A mathematical treatment of the subject has been introduced only when necessary; even then a rudimentary knowledge of mathematics only is required for a clear understanding of the subject matter.
I wish to express my appreciation of the courtesy the various electrical manufacturing companies have shown in furnishing me with the cuts used in the book.
