Izinzwa zeHholo zisuselwa emthethweni wehholo. Umphumela wehholo yindlela eyisisekelo yokutadisha izakhiwo zezinto zokwenziwa ze-semiconductor. Ukuhlanganiswa kwehholo kulinganiswe yi-Hall Fech Circliver kunganquma amapharamitha abalulekile njengohlobo lokuvuselelwa, ukuthwala ukuthwala kanye nokuhamba kwe-carriers kwezinto zokwenziwa ze-semiconductor.
Ukuhlela ngohlobo oluthile
Izinzwa zeHholo zihlukaniswe izinzwa zehholo le-linear Hall kanye nezinzwa zehholo lehholo.
1. I-Linear Hall Sensor iqukethe into yehholo, i-amplifier eqondile kanye nomlandeli we-emitter, kanye nemiphumela ye-analog analog.
2
Izinto ezenziwe ngezinto zokwenziwa ze-semiconductor ezisuselwa emthethweni wehholo zibizwa ngokuthi izakhi zeHholo. Inezinzuzo zokuzwela amasimu kazibuthe, elula ngesakhiwo, ngobukhulu, ububanzi ekuphendukeni imvamisa, elikhulu ekuguqukeni kwamandla kagesi, kudala impilo yensiza. Ngakho-ke, isetshenziswe kabanzi emasimini okulinganisa, ezenzakalelayo, ikhompyutha kanye nobuchwepheshe.
Muhlelo lokusebenza lwe-ain
Izinzwa ze-Hall Effect zisetshenziswa kabanzi njengezinzwa zesikhundla, ukulinganiswa kwesivinini sokujikeleza, ukushintshwa komkhawulo kanye nokulinganisa kokugeleza. Amanye amadivaysi asebenza ngokususelwa emphumeleni wehholo, njengehholo lezinzwa zamanje, ukushintshwa kweqabunga le-hallf effect, kanye ne-Hall Effect Sensors yamandla kagesi. Okulandelayo, inzwa yesikhundla, inzwa yejubane elijikelezayo kanye nokushisa noma inzwa yokushisa noma inzwa yengcindezelo kuchaziwe ikakhulukazi.
1. Inzwa yesikhundla
Izinzwa ze-Hall Effect zisetshenziselwa ukuzwa ukunyakaza ngokuslayida, kulolu hlobo lwenzwa luzoba negebe elilawulwa ngokuqinile phakathi kwento yehholo kanye nozibuthe, namandla kazibuthe azoshintsha njengoba uMagnet azohamba emuva nakwi-grap ebekiwe. Lapho into iseduze neNorth Pole, insimu izoba yiminyaka, futhi lapho into iseduze neSouth Pole, amandla kazibuthe azoba nethemba. Lezi zinzwa zibizwa nangokuthi izinzwa zokusondela futhi zisetshenziselwa ukuma okunembile.
2. Inzwa esheshayo
Ngokuzwa ngokusheshisa, inzwa ye-Hall Effect ibekwa ngokubhekana nosizi olujikelezayo. Lokhu kujikeleza uzibuthe kukhiqiza amandla kazibuthe adingekayo ukusebenzisa inzwa noma into yehholo. Ukuhlelwa kwama-magnets ajikelezayo kungahluka, kuya ngokuya kohlelo lokusebenza. Amanye alawo malungiselelo abeka uMagnet oyedwa emgodini noma i-hub noma ngokusebenzisa ama-ring magnets. Inzwa yehholo ikhipha umgadli ophuma njalo lapho ibhekana nozibuthe. Ngokwengeziwe, la ma-pulses alawulwa yiprosesa ukuthola nokubonisa ijubane ku-RPM. Lezi zinzwa zingaba izinzwa zokukhipha zedijithali noma eziqondile.
3. Ukushisa noma inzwa yokucindezela
Izinzwa ze-Hall Effect nazo zingasetshenziswa njengengcindezi kanye nezinzwa zokushisa, lezi zinzwa zihlanganiswa nengcindezelo ephikisana ne-magnets efanelekile, futhi umhlangano kazibuthe we-bellets afaka i-hallf fict nto emuva naphambili.
Endabeni yokulinganisa ingcindezi, ama-bellows angaphansi kokunwetshwa nokuwohloka. Izinguquko ezingcupheni zibangela umhlangano kazibuthe ukuze usondele eduze kwe-Hall Fead element. Ngakho-ke, i-Volfage Emiphumela Emiphumela ilingana nengcindezi esetshenzisiwe.
Endabeni yezilinganiso zokushisa, umhlangano weLellows uvalwe ngegesi ngezici ezaziwayo zokunwetshwa kwe-thermal. Lapho igumbi lifudumele, igesi ngaphakathi kwe-bellows iyanda, okubangela inzwa ukuthi ikhiqize ngokulingana okulingana nokushisa.
