EXCERPT: preface - This work is an outgrowth of the author's earlier Electric Machinery and Control, originally published in 1964. In revising, supplementing and updating that work, it became clear that two volumes were necessary to present the material properly and keep pace with the state-of-the-art. A variety of reasons dictated this choice. The original work was already fairly large (over 700 pages) and the contemplated new material would inevitably result in a most unwieldy and expensive volume. A logical division between electric machinery theory and control applications of electric machinery already exists in the literature. Numerous works already exist in separate volumes in these areas, so there is a precedent for such a dichotomy. The student who requires a background in the theory of electric machines and their characteristics should be introduced to the subject in a way that is different from that required by the practicing engineer and technician in the field. The latter, primarily, are interest in the control and commercial applications of electric machinery covered in the second volume, although reference to this first volume may occasionally be required. This first volume, therefore, is a text which reflects the feedback from teachers and students who used the earlier Electric Machinery and Control . . . Size: 8vo - over 7¾" - 9¾" tall.
