Excerpt from Principles of Electrical Design: D. C, and A C. Generators The book is intended mainly for the use of students following courses in Electrical Engineering, and since the application Of fundamental laws to the practical problems of the engineer can be adequately illustrated by the few examples which have been selected, there would appear to be no reason for adding new material in the form of additional design problems. The revision covers many minor alterations which are mainly corrections Of errors which have crept into the first edition; but the method of deriving the formula for the flux cut by the short circuited coil during commutation has been modified, and a new treatment has also been introduced in connection with the arma ture m.m.f. In alternating current generators. Two or three new cuts have been made to replace those in the first edition which it was thought might be modified with advantage.
