Hall shidma

The saamayn Hall waa aasaas u ah adeegsiga tiknolojiyada caadi ah oo aan xiriir diiwaangelinta wajiga of qiyaas, dhaqdhaqaaqa iyo xawaaraha wareeg ah walxaha ferromagnetic.

Waa maxay shidma Hall ah, waxaa suurtagal ah in la fahmo, si ay u fahmaan in geedi socodka saamaynta dhaca waxa ku jira. Waqtiga maris ah ee hadda ku dhex jirka waslad khafiif ah oo dhinaca gaadhya markii beer magnetic dhacdaa at qaybo dhammaadka saxan ee transverse jihada ay u dhaqdhaqaaqa hadda ah, farqi iman kara waxaa la aasaasay. Waxaa sabab u ah sharciga Lorentz ah, taas oo uu abuurayaa xaqiiqada ah in ay sabab u tahay saameynta ay duurka ku magnetic tokonositeli u muuqdaan in ay weecinno cidhifyada saxanka. The keentay kala duwan yihiin laga yaabo in si toos ah uu u dhigmaa baaxadda wax soo saarka dulinka ee xoogga duurka iyo hadda H • I. ah

Maqnaanshaha duurka magnetic ee ka daadanayo electron uusan dhici dhalanrog. Marka field magnetic ah ciidamada Lorentz ku lug leh diidmada electrons iyo keeni foorarsiga of trajectories ay. Waddooyinkiisa Kuwanu waa sababta raasamaal soo oogay negative hal dhinac oo ahaa wasladdii. dhinaca ka soo horjeeda ee ahaa wasladdii khafiifka adeegtaa sida site ka mid ah raasamaal la'aan ah bedelo wanaagsan. fiirsashada of eedeeyay dushiisa of Wajiyada soo horjeeda ee ahaa wasladdii waa sababta duurka korontada jihada transverse, kaas oo la odhan jiray duurka Hall ah. Geedi socodka sii ilaa lacag lagu keydiyo ilaa muuqashada EMF transverse ma buuxin karaan ciidamada, kuwaas oo loo ahbaa beerta magnetic. Markaas Jaha hab-socodka taagan, taas oo electrons dhaqaaqo jihada a barbar cidhifyada saxanka, sida ay ka maqan yihiin beerta magnetic.

Hall shidma, qalab samaynta

Qoraalkani wuxuu ku Semiconductor of shidma Hall a in la-macmalay, side noqon waa ma aha oo kaliya sare, laakiin sida ugu macquulsan ku tiirsan tahay qiyamka heerkulka, loo yaqaan Wehliyaha Hall ah, oo uusan u dhaqaaqin awood u sidayaal. Waayo, xulashada ee wax Semiconductor (target - si ay u sameeyaan shidma Hall) si ay hagaan meesha isticmaalka.

Wehliyaha Hall ayaa waxaa lagu qeexaa by baahida loo qabo in cabbirka of induction magnetic field, hadda ka marayo tijaabada la dhumucdiisuna dhigay. Iyadoo aqoonta qiimaha Wehliyaha Hall ah, waxaa suurtagal ah in la dhiso fiirsashada of sidayaal mas'uul ee jirka ka mid ah saxanka, kaas oo dhigmayn in ay wax soo saarka ee Wehliyaha Hall of lacag electron ah.

Semiconductors waxaa sida caadiga ah laga codsadaa iyadoo ay goobjoog ka ahaayeen tabinta elektarooniga ah ay sabab u tahay xaqiiqda ah in ay leeyihiin dhaqdhaqaaqa side u badan ka badan kuwa semiconductors in muujiyaan conductivity nooca-p. U hubso in la ogaado in guryaha jirka ah ee qalabka Semiconductor noqon kartaa mawduuca inuu isbedel la taaban karo, taas oo ku xidhan nooca iyo inta nijaasta la soo bandhigi doonaa iyaga in.

Hall shidma technology for soo saarka

Soosaarka canjeero Semiconductor loogu isticmaalo shidma Hall wuxuu noqon karaa sida soo socota ah,

1. Hall cabbay saxan crystal qaabka doonayo ee bar ah crystal hal.

2. Hel saxan Hall si substrate ah by moobeyl lakabyada thinnest qalabka Semiconductor.

dareemayaal Hall Baaxadda

Isticmaalka dareemayaal Hall toosan yihiin si weyn loo qaybiyey foomka:

- dareemayaal hadda;

- actuators xawaare variable,

- wareeggeedii gacanta iyo ilaalinta baabuurta;

- dareemayaal booska;

- dareemayaal socodka;

- matoorrada brushless DC ,

- potentiometers contactless;

- shidma xagal wareeg;

- dhaanta meydadka ferromagnetic;

- dareemayaal gariirka,

- tachometer.

Macluumaadka ku xusan maqaalka waxa ay kaa caawin in akhristaha haddii ay dhacdo dood ku saabsan waxa shidma Hall a doonaa.
