Michael faraday (1791September 22 ~1August 25, 867), a famous self-taught scientist, was born in a poor blacksmith's family in Newtown, Surrey, and only attended primary school. 183 1 year, he made a key breakthrough in the field of electric field and changed human civilization forever.
Michael faraday is a student and assistant of the famous British chemist David. His discovery laid the foundation of electromagnetism and was the pioneer of Maxwell. Faraday first discovered electromagnetic induction on1831/kloc-0+017, and then obtained the method of generating alternating current. 183 1 year1year1October 28th Faraday invented the disc generator, which is the first generator created by human beings.
Because of his great contribution to electromagnetism, he is called "the father of electricity" and "the father of alternating current".
The development history of alternating current;
When electromagnetic induction was discovered, the method of generating alternating current was known. The early finished products were developed by Englishman michael faraday and Frenchman Park Jungsu Pixar.
1882, British electrician James Gordon built a large two-phase alternator. Lord Kelvin and Sebastian ziani de Ferranti developed early alternators with frequencies ranging from 100 Hz to 300 Hz.
189 1 year, nikola tesla obtained the patent of alternator.
189 1 year later, power supply will be provided by multiphase alternator. Thereafter, the AC frequency of the alternator is usually designed between 16 Hz and 100 Hz, and it is used in conjunction with arc lamps, incandescent lamps or motors.
According to the law of electromagnetic induction, when the magnetic field around a conductor changes, an induced current will be generated in the conductor. Usually, the rotating magnet is called rotor, and the fixed group in the coil with conductor wound on the iron core is called stator. When it passes through a magnetic field, it generates an electric current. The basic machine that generates alternating current is called alternator.
