Hall inzwa

Umthelela Hall isisekelo ukusetshenziswa ubuchwepheshe ezivamile non-contact kokubhalisa esigabeni se isilinganiselo, ukunyakaza kanye nesivinini ukuzungeza izinto ferromagnetic.

Uyini inzwa Hall, kungenzeka ukuba baqonde, ukuqonda empeleni izinqubo ezenzeka kuwo. Ngesikhathi ukudlula wamanje ngomzimba ipuleti ohlangothini longitudinal lapho kazibuthe kwenzeka ngesikhathi izingxenye ekupheleni ipuleti endaweni transverse isiqondiso ukunyakaza zamanje, akha umehluko ezingaba is. Sibangelwa umthetho Lorentz, owenza izindlela yokuthi ngenxa ithonya kazibuthe tokonositeli bathambekele bayeke emaphethelweni plate. I kwaphumela umehluko okungase ithunzi elehlayo ubukhulu komkhiqizo Vector yezikhwepha ensimini futhi zamanje H • I.

In the ukungabikho kazibuthe at yokucucuza electron ingekho ukuhlanekezela. Lapho i kazibuthe Lorentz amabutho ehilelekile ukwenqaba electron futhi babangela ukwephulwa kwale trajectories yabo. Lezi izindlela ayimbangela yazo ekuqongeleleni amacala omubi kolunye uhlangothi plate. Esesayidini plate ukhonza njengelungu esizeni ekuqongeleleni ukukhokhiswa omuhle uncompensated. I lokuhlushwa amacala phezu ubuso okuphambene plate siyimbangela emkhakheni kagesi ohlangothini transverse, okwakubizwa ngokuthi i eHholo ensimini. Inqubo uyaqhubeka kuze kube isitoreji icala kuze kokuvela EMF transverse ngeke sigqibe amabutho zazo eyenziwe kazibuthe. Khona-ke ukukhwezwa umile inqubo Imodi, lapho ama-electron ukuhambisa ngendlela isiqondiso parallel emaphethelweni ipuleti, njengoba ngokungabi bikho kazibuthe.

Hall inzwa, okwenza izinto

Indaba Semiconductor ka inzwa Hall ekhiqizwa, esiphathiswa akufanele kwenziwe nje okusezingeni eliphezulu, kodwa ngangokusemandleni sincike amagugu lokushisa, eyaziwa ngokuthi Coefficient Hall, futhi ezihambayo abathwali ikhono. Ukuze ukukhethwa Semiconductor impahla (target - ukwenza inzwa Hall) ukuqondisa endaweni yayo ukusetshenziswa.

Coefficient Hall kuchazwa mayelana nesidingo nesilinganiso of magnetic field lokungeniswa, wamanje ngokusebenzisa isampula ne setha Uhlonze lwalo. Ngokufunda ukubaluleka Coefficient Hall, kungenzeka ukusungula lokuhlushwa kwenkokhiso abathwali emzimbeni we ipuleti, okuyinto inhlukanozigaba ukuba umkhiqizo Coefficient Ehholo icala electron.

Semiconductors ngokuvamile sisetshenziswa nokuba khona conduction electronic ngenxa yokuthi ukuthi kuningi ephakeme yenethiwekhi ukuhamba kunalawo Semiconductors ukuthi abonise p-uhlobo conductivity. Qiniseka ukwazi ukuthi Izakhiwo zanoma Semiconductor izinto kungaba kuncike izinguquko eziphawulekayo, kuye ngokuthi hlobo luni nokuthi zingaki ukungcola ziyokhokhwa kuzo.

Hall inzwa ubuchwepheshe for yokukhiqiza

Okwenza esilucwecwana Semiconductor ukuze zisetshenziswe esikhathini inzwa Hall kungaba kanje:

1. Hall baphuza crystal ipuleti ukuma ofiselekayo we olulodwa crystal ibha.

2. Thola ipuleti Hall substrate by sishaye izingqimba thinnest ka Semiconductor izinto.

Izinzwa Ububanzi Hall

Ukusebenzisa komugqa Hall nezinzwa esakazwa ifomu:

- Izinzwa zamanje;

- actuators ngesivinini variable;

- ukulawula izifunda kanye nokuvikelwa motor;

- isikhundla izinzwa;

- ukugeleza izinzwa;

- izinjini brushless DC ;

- imininingwane yokuxhumana potentiometers;

- Ukujikeleza engela inzwa;

- imitshina emizimbeni ferromagnetic;

- vibration izinzwa;

- tachometer.

Imininingwane ezibekwe sihloko Kuzokuba lisizo umfundi uma kwenzeka ingxoxo kulokho inzwa Hall.
