Theory of uniform-motion electromagnetic machines

2014 In the first part of this paper, analogies between conventional rotating electromechanical machines (motors, alternators, etc...) and periodic-structure microwave electron tubes are made, and a common theory is elaborated. In the second part, this theory is used to define new types of rotating machines that will operate with electrical currents having a very wide frequency spectrum, or at variable frequency, or independently of the rotational velocity. Different applications for these machines are envisaged and some problems involved in their use are mentioned. REVUE DE PHYSIQUE APPLIQUÉE TOME 13, MAI 197 !
