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.

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 ...
The magnet was made of 18 turns of bare copper wire (insulated wire had not yet been invented). [1] William Sturgeon (/ ˈ s t ɜːr dʒ ə n /; 22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnet and the first practical electric motor.
[7] [8] [9] The invention of the first model electric vehicle is attributed to various people. [10] 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 ...
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.
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.
The electric motor brings on the first juke box with cylinders – even before flat disk records were widely available. Thomas Edison discovers thermionic emission. This effect forms the basis for the vacuum tube and the cathode ray tube. approximately 1893: The selenium phototube invention allows the conversion of brightness values into electrical
