Abstract
MANY problems connected with the design of electrical machines and apparatus are discussed in this volume. It is shown that in many cases sufficiently accurate solutions can be found by applying elementary mathe-matics and known physical laws. When designing high-voltage insulators, the reader is shown how to picture for himself the tubes of electrostatic induction in the insulator and the surrounding space, and when studying the action of electric generators and motors he pictures the conductors as cutting the magnetic flux. A concrete mental conception can thus be obtained of the actions which produce easily measurable results. The author points out that the difference between a laboratory course and a course in machine design is that the former is mainly concerned with analysis, separating out the losses in a machine, whilst the latter is concerned with synthesis, the building up of a machine. A course in design is a link between academic studies and practical engineering. It helps to develop engineering judgment, the student learning the relative importance of the many factors which enter into a commercial problem.
