Hall sensor: mabda'a iyo codsiyada

Hall saamayn helay magiciisiina wuxuu u saynisyahan E.G.Hollu yaa helay 1879, marka la taargooyinka dahab ah oo khafiif ah oo shaqo ku mahad ay. Saamaynta waa muuqaalka kore ee stress by gelinayn taarikada tabinta duurka a magnetic. danab Tan waxaa si fiican loo magacaabay - danab Hall ah. codsiga warshadaha ee saamaynta this ayaa waxaa suurtageliyey kaliya ka dib markii 75 sano ka dib markii la ogaaday, markii ay bilaabeen inay la soo saaray filimka Semiconductor leh guryaha qaarkood. Sidaas daraaddeed waxaa ku mabda 'a shidma Hall ee hawlgalka ku salaysan yahay saamaynta eponymous. shidma Tani waa qalab lagu qiyaaso xoogga field magnetic. On ay ku salaysan yihiin aaladaha kale oo badan: dareemayaal barakaca field magnetic angular oo toosan, hadda, socodka, iwm Hall shidma uu leeyahay tiro ka mid ah faa'iidooyinka, mahad taas oo si weyn loo isticmaalo. First, hawlgalka aan xiriir meesha ay xirtaan farsamo. Marka labaad, waa ay fududahay in la isticmaalo kharash xad hooseeyo. Saddexaad, qalab uu leeyahay size yar. Tan afraad, isbedelka inta jeer jawaab noqonin mid horseeda in a wareeg ee xilligan ee cabbirka. Fifth, korontada shidma signal uusan qarxi dabiiciga ah iyo wareegay isla markiiba dials joogto ah. Uu doodista kale: gudbinta signal aan ikazheniya, dabeecadda non-xiriir of signal laftiisa, nolosha adeeg ficil ahaan aan xad lahayn, kala duwan oo Big ee mawjadaha, iwm Si kastaba ha ahaatee, waxay leeyihiin cillado ay, ugu weyn ee oo u nugul yihiin faragelin electromagnetic ee circuit korontada iyo isbeddel ah ee heerkulka.

Mabda'a hawlgala ee shidma Hall ah. Hall shidma - a gool design, hal dhinac oo ah taas oo ah Semiconductor, oo ku kale - a joogto ah magnet. Marka socodka hadda ee beerta magnetic ku electrons ee dulinka ciidan oo dadab waa in labada hadda iyo beer. Sidaas oo kale ayaa dhinac ee saxanka uu jiro farqi u iman kara. shidma Farqiga waxaa ah xijaab kaas oo khadadka duurka ku xiran yihiin. Waxay ka hortagtaa formation farqiga saxan iman kara. Haddii farqiga ma aha shaashadda, ka yar tallaabada duurka a magnetic la saxan Semiconductor laga saaro farqiga u iman kara. Marka marinka screen (garbaha rotor) ilaa farqiga in induction ah Bannaanka dhafan noqon doontaa eber, iyo danab wax soo saarka u muuqataa.

Hall shidma iyo aaladaha ku salaysan waxa on hubkaas ayaa loo isticmaalaa in duulista, baabuurta, instrumentation iyo warshadaha kale oo badan. Waxaa loo soo saaray shirkadaha sida si fiican u yaqaan sida Siemens, Micronas Intermetall, Honeywell, Melexis, Device Analog, iyo kuwo kale oo badan.

core ugu badan ee loo yaqaan ee wax soo saarka shidma Hall kaas oo badala gobolka macquulka ah marka duurka ku magnetic ka badan qiimaha gaar ah. Gaar ahaan si weyn loo isticmaalaa in kuwan matoorrada dareemayaal brushless sida a shidma booska rotor (DPR). dareemayaal Logic Hall waxaa loo isticmaalaa in qalabka .Wadashaqayntaas ah, nidaamka suuroggalaan, akhristayaasha card magnetic, furayaasha, biiro contactless ah, iwm Loo dareemayaal toosan muhiim waxaa loo isticmaalaa si loo qiyaaso toosan ama barakaca angular iyo hadda korontada.
