Abstract :
Traditional introductory lecture courses, dealing with the steady state only for each type of electrical machine, and accompanying laboratory courses in which steady-state terminal characteristics are measured, have proved an inadequate preparation for an electrical-engineering career today, when machines in systems, often controlled by computers, are of growing importance, and the transient state is of greater interest than the steady state. The paper describes a new introductory course that shows clearly the common fundamentals of all electrical machines and other transducers, leads in a shorter time than is usual to a much improved understanding, and lays firm foundations for the study of the general theory, which deals with operation of machines under all conditions. A new generalised electrical machine was developed for the course and is described. The new theoretical treatment has significantly improved the derivation of some important fundamental relationships and these are given.
