The evaluation of the performance of traction and braking systems by calculation is very difficult because of the complexity of the theoretical modelling of the physical phenomena involved, especially in continuous media and more particularly ferromagnetic ones. Moreover, the components of the transport system at present under consideration involve new electromagnetic devices which are not amenable to the methods of calculation used for the design of conventional electrical machines, the performance of which is most often, we have to admit, calculated inductively. Up to the present, in the absence of a particular recognised methodology, the development of these components has proceeded by way of full size construction which is very costly, principally because of the magnitude of the test facilities required. Such a procedure invites the risk, if a difficulty is encountered and such is quite normal during early testing, of premature abandonment of promising lines of investigation. For this reason the Institut de Recherche des Transports (Transport Research Institute) directed its efforts to research into the electromagnetic laws of similitude so that the scientific and technological community might be made aware of them.
