Guhindura urubingo hamwe ningaruka zingirakamaro
Imashini ya rukuruzi ikoreshwa mubintu byose kuva mumodoka kugeza kuri terefone ngendanwa. Ni uruhe rukuruzi nkwiye gukoresha hamwe na sensor ya magnetiki? Nakagombye gukoresha sensor ya salle ya Hall cyangwa urubingo? Nigute rukuruzi igomba kwerekezwa kuri sensor? Ni ubuhe bworoherane nkwiye guhangayikishwa? Wige byinshi hamwe na K&J kugenda-yerekana magnet-sensor ikomatanya.

Guhindura Urubingo ni iki?

Ibyuma bifata ibyuma bibiri bya Hall hamwe nu rubingo. Urubingo rwurubingo ruri iburyo.
Urubingo ni urubingo rwamashanyarazi rukoreshwa numurima wa rukuruzi. Igizwe na joriji ihuza urubingo rwicyuma rwa ferrous mu ibahasha yikirahure. Guhuza mubisanzwe birakinguye, nta mashanyarazi akora. Ihindura ikora (ifunze) izana magnet hafi ya switch. Iyo magnet imaze gukurwaho, urubingo ruzasubira mumwanya wambere.

Sensor ya Hall ni iki?
Icyuma cyerekana ingoro ni transducer itandukanya ibyasohotse mumashanyarazi asubiza impinduka mumashanyarazi. Muburyo bumwe, ibyuma byerekana ingaruka za Hall birashobora gukora imirimo isa nkurubingo, ariko nta bice byimuka. Tekereza nk'ikintu gikomeye-cya leta, cyiza kubikorwa bya digitale.

Niki muri ibyo byuma byombi bikwiranye no gusaba kwawe biterwa nibintu byinshi. Ibintu birimo ikiguzi, icyerekezo cya magneti, intera yumurongo (guhinduranya urubingo mubisanzwe ntibishobora gukoreshwa hejuru ya 10 kHz), ibimenyetso byerekana ibimenyetso hamwe nigishushanyo mbonera cya logique.

Magnet - Icyerekezo cya Sensor
Itandukaniro ryibanze hagati yurubingo rwahinduwe na sensor ya Hall nicyerekezo gikwiye gisabwa kugirango rukore rukuruzi. Ibyuma bifata ibyuma byubaka bikora iyo magnetiki yumurongo wa perpendicular kumurongo ukomeye wa sensor ikoreshwa. Benshi bareba magnet ya pole yepfo kugirango barebe ahantu hagaragara kuri sensor, ariko reba urupapuro rwerekana sensor yawe. Niba uhinduye magnet inyuma cyangwa kuruhande, sensor ntishobora gukora.

Guhindura urubingo nigikoresho cyimashini gifite ibice byimuka. Igizwe ninsinga ebyiri za ferromagnetic yatandukanijwe nicyuho gito. Imbere yumurima wa magneti uhwanye nizo nsinga, bazakoraho, bakora amashanyarazi. Muyandi magambo, umurongo wa magneti wa magneti ugomba kuba ugereranije nu murongo muremure wurubingo. Hamlin, uruganda rukora urubingo, afite inyandiko nziza yo gusaba kuriyi ngingo. Harimo igishushanyo kinini cyerekana uturere nicyerekezo aho sensor izakorera.
Icyerekezo gikwiye cya Magneti: Icyuma cyerekana ingoro (ibumoso) nu guhinduranya urubingo (iburyo)
Twabibutsa ko izindi miterere zishoboka kandi zikoreshwa kenshi. Kurugero, ibyuma byerekana ibyuma bya Hall birashobora gutahura ibyuma byizunguruka "umufana." Icyuma cyumufana kinyura hagati ya rukuruzi ihagaze na sensor ihagaze. Iyo ibyuma biri hagati yibi byombi, umurima wa magneti woherezwa kure ya sensor (uhagaritswe) hanyuma switch irakinguka. Iyo ibyuma byimutse, rukuruzi ifunga switch
