Hungarian, physicist and unsung father of the dynamo and electric motor; invented the first commutated rotary electromechanical machine with electromagnets. [ 3 ] [ 5 ] He invented the commutator . In 1828, Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator , rotor and commutator.
As early as 1834, he developed a battery-powered electric motor, along with his wife Emily Davenport. They used it to operate a small model car on a short section of track, paving the way for the later electrification of streetcars. [2] It is the first attempt to apply electrification to locomotion.

An electric motor is a machine that converts electrical energy into mechanical energy. ... These motors were invented to drive the capstan(s) of magnetic tape drives ...
In 1999, grandsons, John L. Sprague and Peter Sprague cut the ribbon and started an 1884 Sprague motor at a new exhibit at the Shore Line Trolley Museum, where a permanent exhibit, "Frank J. Sprague: Inventor, Scientist, Engineer", tells the story of the role of the "father of electric traction" and the role of electricity in the growth of cities.
In 1828, the Hungarian priest and physicist Ányos Jedlik invented an early type of electric motor, and created a small model car powered by his new motor. Between 1832 and 1839, Scottish inventor Robert Anderson also invented a crude electric carriage. [11]
Kettering invented an easy credit approval system, a precursor to today's credit cards, and the electric cash register in 1906, which made ringing up sales physically much easier for sales clerks. Kettering distinguished himself as a practical inventor. As he said, "I didn't hang around much with other inventors and the executive fellows.
In 1882 he invented the electric fan by placing a two-bladed propeller on the shaft of an electric motor. It was known as the "buzz fan." [4] He was awarded the John Scott Medal for this invention in 1904 by the Franklin Institute. [4] [16] Wheeler's patent for his Electric Fire-engine System was filed May 23, 1882. [1]
In 1828, Ányos Jedlik, a Hungarian who invented an early electric motor, constructed a tiny model car powered by his new motor. [8] In 1834, Vermont blacksmith Thomas Davenport, the inventor of the first American DC electric motor, installed his motor in a small model car, which he operated on a short circular electrified track.
