Electric generator

In electricity generation, a generatoris a device that converts motive power (mechanical energy) into electrical power for use in an external circuit. Sources of mechanical energy include steam turbinesgas turbineswater turbinesinternal combustion engineswind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids.

The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators.
 

AC Generator
An alternator is a type of generator that converts mechanical energy into electrical energy in the form of alternating current.
 
Development history
  • When electromagnetic induction was discovered, the method of generating alternating current was known. The early finished products were developed by Michael Faraday and Polit Pixi.
  • In 1866, Werner von Siemens proposed the working principle of the generator, and an engineer from Siemens completed the first human alternator.
  • In 1882, British electrician James Gordon built a large two-phase alternator. Lord Kelvin and Sebastian Ferranti developed early alternators with frequencies ranging from 100 Hz to 300 Hz.
  • In 1891, Nikola Tesla obtained a patent for a ''high frequency'' (15,000 Hz) alternator.
  • After 1891, multi-phase alternators were used to supply electric current. After that, the alternating current frequency of alternators was usually designed to be between 16 Hz and 100 Hz, and used with arc lamps, incandescent lamps or electric motors

When the magnetic field around the conductor changes, an induced current is generated in the conductor. Normally, a rotating magnet is called a rotor, and a fixed set of conductors wound in a coil on an iron core is called a stator. When it crosses the magnetic field, it generates current.
 
DC generator
 
A DC generator is a type of generator that converts mechanical energy into DC electricity.
  • In 1866, Werner von Siemens and other engineers from Siemens invented the first DC generator.
  • 1882: Edison Electric Light Company established the third power station in London, installed three 110-volt DC generators, which can supply power for 1,500 16-watt incandescent lamps.
With the popularity of alternating current, large direct current generators have become history. [Source request] Now, if DC power is needed, a rectifier will be used to rectify AC power into DC power.

在公元1831年,法拉迪第将一个封闭电路中的导线通过电磁场,导线转动有电流流过电线,法拉第因此了解到电和磁场之间有某种紧密的关连,他建造了第一座发电机原型,其中包括了在磁场中迥转的铜盘,此发电机产生了电力。在此之前,所有的电皆由静电机器和电池所产生,而这二者均无法产生巨大力量。但是,法拉第的发电机终于改变了一切。
 
 
交流發電機
交流發電機是發電機的一種,它可將機械能轉換成交流電流形式的電能。
 
 
發展史
當發現了電磁感應後,產生交流電流的方法則被曉得。早期的成品由麥可·法拉第與波利特·皮克西等人開發出來。
1866年,維爾納·馮·西門子提出了發電機的工作原理,並由西門子公司的一名工程師完成了人類第一台交流發電機。
1882年,英國電工詹姆斯·戈登建造了大型雙相交流發電機。開爾文勳爵與塞巴斯蒂安·費蘭蒂開發早期交流發電機,頻率介於100赫茲至300赫茲之間。
1891年,尼古拉·特斯拉取得了「高頻率」(15,000赫茲)交流發電機的專利。
1891年後,多相交流發電機被用來供應電流,此後的交流發電機的交流電流頻率通常設計在16赫茲至100赫茲間,搭配弧光燈、白熾燈或電動機使用。
當導體周圍的磁場發生變化,感應電流在導體中產生。通常情況下,旋轉磁體稱為轉子,導體繞在一個鐵芯上的線圈內的固定組,稱為定子,當其跨越磁場時,便產生電流。


直流發電機
 
直流發電機是發電機的一種,它可將機械能轉換成直流電的發電機。
1866年,維爾納·馮·西門子與西門子公司其他工程師發明了人類第一台直流發電機。
1882年:愛迪生電燈公司在倫敦建立了第3座發電站,安裝了3台110伏特直流發電機,可為1500個16瓦的白熾燈供電。
隨著交流電的普及,大型直流發電機已成為歷史。[來源請求]現在,如果需要直流電,會利用整流器把交流電整流成直流電。
