More information on the evolution of the engine

The Belgian engineer-inventor and inventor Zénobe Théophile Gramme in 1869 built an engine, almost a generator, which he called the inverse machine, that is, when connected to an electric current produced motor energy. This energy, when caused by a motor force, produced electricity. It was called the ‘Gramme Dynamo’ and shown in Vienna in 1873. A few years later, it was also exhibited at the Technical University of Graz, Austria, where he charmed the then Yugoslav pupil Nikola Tesla.

Physicist and engineer rexnord cb22436h Tesla began researching further improvements to this already successful dynamo. In 1883 he introduced the first AC generator, where its poles are reversed. From this the current began to be generated alternately, as they arrive at the still takes today and then, invented the electric motor without switch. However, the alternating current that would have been the other great revolution in electricity did not cause Tesla’s desired impact on the European scientific community at the time. This led the researcher to seek new opportunities in the United States in 1884. That same year he sold the patent rights of the inventions to George Westinghouse, owner of an electric company.
