Tesla's most famous invention the AC motor. An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this would be the conversion of mechanical energy into electrical energy and is done by an electric generator. Nikola Tesla (July 10, 1856 - January 7, 1943) was a Serbian-American inventor, electrical engineer, and futurist. He was an important contributor to the use of commercial electricity, and for developing the modern alternating current (AC) electrical supply system. Because of his 1894 demonstration of short range wireless communication through radio and as the eventual victor in the "War of Currents" (Tesla vs. Edison), he was widely respected as one of the greatest electrical engineers.
