The electric machines revolutionized the world, bringing modernity when used in the industry. The construction of electric motors was begun in 1813 by Michael Faraday who, by inserting a magnet into a coil of copper wire, caused it to rotate through an electric current. From 1832 when the scientist Salvatore Dal Negro built the first AC machine, several scientists, inventors and scholars began to analyze the part of electrical physics. Around 1880, an Austrian inventor named Nikola Tesla, decided to study the rotating field. Then came the induction machine, the project being funded originally by George Westinghouse. This North American, born in New York, learned from his father to make and repair agricultural machinery, for he was already a curious in the area of motion science.
The discovery of the induction machine boosted the Industrial Revolution, becoming the main type of electromechanical converter used, because the power system is found more frequently in alternating current, like the electrical network that supplies our houses. This machine that converted electrical energy into mechanical energy, the principle of operation of the electric motors, went on to be used in several uses.
