Mene ne ikon amp

A 1820, mashawarta Faransa likita Andre Marie Ampere (shi ne a masa mutunci mai suna sashi ne na auna na lantarki) ya tsara daya daga cikin muhimman hakkokin dokokin dukkan lantarki aikin injiniya. Daga bisani, wannan dokar shi samu da sunan da ikon amp.

Kamar yadda aka sani, a lokacin da nassi na lantarki ta hanyar da shugaba faruwa a kusa da kansa (secondary) Magnetic filin tsanani Lines wanda ya samar da wani irin na juyawa harsashi. The shugabanci daga cikin wadannan Lines na Magnetic shigar da aka ƙaddara ta amfani da hannun dama mulki (na biyu sunan "dama-hannu mulki"): tunani hannun dama clasps da shugaba sabõda haka, domin cajin barbashi daidai da shugabanci nuna lankwasa yatsa. A sakamakon haka, da sauran hudu yatsunsu, clasping waya, ma'ana ga filin juyawa.

Idan ka sanya wadannan biyu a layi daya conductors (bakin ciki waya), sa'an nan a kan hulda da su Magnetic filayen zai shafi ikon amp. Dangane da shugabanci na halin yanzu a kowane shugaba, su za a iya janyo hankalin ko hanãwa. Lokacin da igiyoyin sunã gudãna a cikin shugabanci, da ikon amp yana a kan su jawo mataki. Haka kuma, igiyoyin a gaban shugabanci Yanã tunkuxe. Wannan ba abin mamaki: yayin kamar zargin tare, a cikin wannan misali, hul] a ba da zargin da Magnetic filayen. Tun da shugabanci na juyawa ne guda, da karshe filin ne vector ware Naira Miliyan Xari, ba bambanci.

A wasu kalmomin, da Magnetic filin abubuwa a wani hanya zuwa ga shugaba, wanda crosses da layi na tashin hankali. Ikon Amp (sabani siffar shugaba) ne niyya daga dabara dokar:

DF = B * I * L * zunubi a.

inda - I - da darajar halin yanzu a cikin shugaba. B - Magnetic shigar da, a cikinsa da conductive abu ne dake; L - dauka yin lissafi da tsawon da shugaba tare da na yanzu (da kuma a cikin wannan hali shi ne zaci cewa shugaba tsawon ta karfin ayan sifili). alpha (a) - a vector kwana tsakanin shugabanci na motsi na cajin barbashi da waje filin Lines. Corollary haka: a lokacin da kwana tsakanin vectors ne 90 digiri shi zunubi = 1 da kuma matsakaicin darajar da karfi.

Vector shugabanci amp iko ne m da dokoki na hagu: tunani sanya hannunsa na hagu haka cewa Lines (vectors) na Magnetic shigar da na waje filin kunshe a cikin bude hannu, da kuma sauran hudu yatsunsu gãfarta nuna shugabanci a cikinsa halin yanzu gudana a cikin shugaba. Sa'an nan da yatsa lankwasa a wani kwana na 90 digiri, nuna shugabanci na karfi aiki a kan shugaba. Idan kwana tsakanin vector na lantarki da kuma wani sabani line shigar da shi ne ma kananan, ya rage wuya da aikace-aikace na mulki a cikin dabino kamata ba kanta hada da shigar da vector, da kuma koyaushe.

Aikace-aikace Ampere sojojin sanya shi yiwuwa don ƙirƙirar lantarki Motors. Mu ne duk saba wa gaskiyar cewa shi ne isa ya jefa cikin canza lantarki iyali nema sanye take da wani engine cewa ta actuating inji zo a cikin sakamako. Kuma game da tafiyar matakai abin da ke faruwa a lokaci guda, babu daya yawa hankulansu. Direction amp ikon ba bayyana da manufa na aiki na injuna, amma kuma domin sanin inda daidai za a aika zuwa ga karfin juyi.

Alal misali, tunanin wani DC motor: ya anga - a frame-akai tare da wani Tuddan. An waje Magnetic filin aka samar da musamman zura sandunan ɗaukarsa. Tun da nada rauni a kan armature, madauwari, sa'an nan a tarnaƙi na yanzu shugabanci counter ga shugaba rabo. Saboda haka, da ampere karfi mataki vector counterclaims. Tun da anga aka kulla da bearings, da juna mataki na vectors ampere karfi ya haifar da wani karfin juyi. Tare da ci gaban da na yanzu darajar yanzu ƙaruwa da kuma iko. Wannan shi ne dalilin da ya sa rated lantarki (kayyade a cikin takardar shaidar for lantarki kayan aiki) da kuma karfin juyi kai tsaye nasaba. Kara halin yanzu da aka iyakance ta constructional siffofin: sectioned Tuddan waya, yawan jũya da sauransu.
