BRIEF EVOLUTION OF ELECTRIC MACHINES TILL THE END OF THE XIXth CENTURY
Development and modernization of electric machines used in modern systems of electric propulsion of ships is impossible without an analysis of their evolution in the development of marine energy. This article describes the most significant historical period associated with the intensive improvement of electric propulsion systems, then found application on ships of various purposes. The given material allows to trace not only the main tendencies of technical modernization of the equipment, but also to outline ways of its further improvement. The article is a scientific basis for beginning researchers dealing with the design and operation of Electromechanical converters. The analyzed information sources cover a wide range of domestic and international publications, from the very first reports on the theoretical possibilities of using electricity to practical implementations that appeared at the end of the XIXth century and associated with the name of M. O. Dolivo-Dobrovolsky, who proposed the 1st three-phase asynchronous motor with squirrel cage rotor.
