Excerpt from Design of Polyphase Generators and Motors During several recent years the author has given courses of lectures at three technical schools in London, on the subject of the design of electric machinery. These three schools were: the Northampton Institute of Technology; Faraday House; and University College. Various methods of procedure were employed and these ultimately developed into a general plan which (so far as it related to the subjects of Polyphase Generators and Polyphase Motors), has been followed in the present treatise. It was the author's experience that the students attending his lectures took an earnest interest in calculating designs of their own, in parallel with the working out of the typical design selected by the author for the purpose of his lectures. At the outset of the course, each member of the class was assigned the task of working out a design for a stipulated rated output, speed and pressure. Collectively, the designs undertaken by the class, constituted a series of machines, and co-operation was encouraged with a view to obtaining, at the conclusion of the course of lectures, a set of consistent designs. If a student encountered difficulty or doubt concerning some feature of his design, he was encouraged to compare notes with the students engaged in designing machines of the next larger and smaller ratings or the next higher and lower speeds. Ultimately the results for the entire group of designs were incorporated in a set of tables of which each student obtained blue prints. At two of these colleges, the "sandwich" system was in operation, that is to say, terms of attendance at the college were "sandwiched" with terms during which the student was employed in an electrical engineering works.

Excerpt from Electrical Machine Design: The Design and Specification of Direct and Alternating Current Machinery A study of design is of the utmost importance to all students, because only by such a study can a knowledge of the limitations of machines be acquired. The machines discussed are those which have become more or less standard, namely, direct-cur rent generators and motors, alternating current generators, syn chronons motors, polyphase induction motors, and transformers; other apparatus seldom offers an electrical problem that is not discussed under one or more of the above headings. The principle followed throughout the work is to build up the design for the given rating by the use of a few fundamental formulae and design constants, the meaning and limits of which are discussed thoroughly, and the same procedure has been followed for the several pieces of apparatus.

Provides the general background for design of electrical motors by placing motor design in the context of the overall drive and its function, and with a survey of the various electrical and mechanical components. The design itself is addressed using an original approach based on first principles: it begins with the design specifications, expresses them in terms of electric and magnetic stresses, establishes appropriate geometry, and arrives at the dimensions. Unconventional topologies are also discussed.

Excerpt from Electrical Engineering: The Theory and Characteristics of Electrical Circuits and Machinery The second edition contains all the material in the original text but much of it has been rewritten and a great deal of new material added. The more important additions include sections on complex alternating waves and wave analysis, on polyphase alternating current circuits, on the construction of the characteristic curves of direct-current generators and motors, on the design of direct and alternating-current machinery, on the Blondel diagram for the synchronous motor, on the symbolic method of analysis of the induction motor, on alternating-current commutator motors, and finally a chapter on electrical measuring instruments. The chapter on direct-current machinery has been entirely rewritten and much enlarged, and to make it complete a short chapter outlining the design of a direct-current generator has been added. This chapter and the other sections dealing with design are not intended to cover the work required in a course on design but only to give the student some idea of the formulae and constants involved.
