Kaw-loop Hall tam sim no sensor thiab qhib-voj Hall tam sim no sensor yog ob hom tam sim no sensor, thiab lawv muaj cov qauv kev ua haujlwm sib txawv thiab kev siv hauv kev ntsuas tam sim no. Kab lus no yuav qhia meej txog cov qauv kev ua haujlwm, cov yam ntxwv thiab daim ntawv thov kev lag luam ntawm kaw-voj Hall tam sim no sensors thiab qhib-voj Hall tam sim no sensors los pab cov neeg nyeem kom nkag siab zoo dua qhov zoo thiab qhov tsis zoo ntawm ob lub ntsuas tam sim no.
Kaw-loop Hall tam sim no sensors ntsuas tam sim no los ntawm Hall effect txoj cai. Nws cov qauv yooj yim muaj cov ntsiab lus Hall, magnetic teb thiab cov lus tawm tswv yim. Cov khoom Hall feem ntau yog ib daim ntawv nyias ntawm cov khoom siv semiconductor. Thaum qhov tam sim no dhau los ntawm cov cuab yeej hloov pauv, qhov chaw sib nqus ua rau lub zog ntawm Hall, yog li hloov lub peev xwm Hall thiab thaum kawg tsim cov teeb liab voltage. Cov lus tawm tswv yim yog lub luag haujlwm rau kev hloov cov lus tawm tswv yim voltage teeb liab rau hauv cov teeb liab tso zis proportional rau tam sim no los ntsuas qhov tam sim no. Lub kaw-voj Hall tam sim no sensor muaj qhov zoo ntawm qhov raug siab, tsis tshua muaj qhov kub thiab txias thiab cov lus teb ntau zaus, thiab tsim nyog rau cov xwm txheej tshawb pom tam sim no uas yuav tsum muaj kev ruaj ntseg thiab ntsuas qhov tseeb.
Nyob rau hauv sib piv, lub qhib-voj Hall tam sim no sensor ncaj qha siv lub voltage teeb liab tso zis los ntawm lub Hall lub caij raws li ib tug tam sim no teeb liab tsis muaj kev koom tes ntawm ib tug tawm tswv yim system. Nws txoj hauv kev ua haujlwm zoo ib yam li qhov kaw-voj Hall tam sim no sensor, tab sis vim tias tsis muaj kev kho cov lus tawm tswv yim, qhov ntsuas qhov tseeb ntawm qhov qhib-voj Hall tam sim no sensor yog qis dua. Txawm li cas los xij, qhov qhib-voj Hall tam sim no sensor muaj qhov zoo ntawm cov qauv yooj yim, tus nqi qis, thiab cov lus teb ceev ceev, thiab tsim nyog rau qee qhov kev thov uas tsis xav tau qhov tseeb tab sis xav tau cov lus teb ceev.
Kaw-loop Hall tam sim no sensors thiab qhib-voj Hall tam sim no sensors muaj lawv tus kheej teb hauv kev siv tswv yim. Kaw-loop Hall tam sim no sensors feem ntau siv nyob rau hauv lub sij hawm saib xyuas thiab tswj cov tam sim no nyob rau hauv teb xws li lub hwj chim systems, industrial automation, thiab kev thauj mus los. Txij li thaum kaw-voj Hall tam sim no sensor muaj cov yam ntxwv ntawm qhov raug siab thiab tsis tshua muaj qhov kub thiab txias, nws tuaj yeem ntsuas qhov ntsuas tam sim no thiab muab cov ntaub ntawv tawm tswv yim raws sij hawm hauv qhov kub thiab txias ib puag ncig.
Open-loop Hall tam sim no sensors feem ntau yog siv rau hauv cov ntawv thov uas tsis tas yuav muaj kev ntsuas siab, xws li kev tswj lub cev muaj zog, hloov hluav taws xob, thiab kev tiv thaiv overcurrent. Vim nws cov lus teb ceev ceev thiab cov qauv yooj yim, qhib-voj Hall tam sim no sensor tuaj yeem ua tau raws li qhov kev thov rau kev saib xyuas sai thiab tswj cov kev hloov tam sim no.
Thaum xaiv qhov ntsuas tam sim no, nws yuav tsum tau txiav txim siab seb puas yuav siv lub voj kaw kaw tam sim no lossis lub voj qhib Hall tam sim no ntsuas raws li cov ntawv thov tshwj xeeb thiab cov cai. Kaw-loop Hall tam sim no sensors yog haum rau lub sijhawm uas yuav tsum tau siab dua ntawm kev ntsuas tam sim no, thaum qhib-voj Hall tam sim no sensors yog tsim rau lub sijhawm uas yuav tsum tau siab dua ntawm kev ceev thiab tus nqi.
Hauv luv luv, kaw-voj Hall tam sim no sensors thiab qhib-voj Hall tam sim no sensors yog ob hom kev ntsuas tam sim no. Lawv ntsuas tam sim no los ntawm kaw-loop tawm tswv yim systems thiab qhib-loop qauv feem. Kaw-loop Hall tam sim no sensors muaj qhov zoo ntawm qhov raug siab, qis qis qis, thiab cov lus teb siab, thiab tsim nyog rau lub sijhawm uas yuav tsum muaj siab rau qhov ntsuas tam sim no; thaum qhib-voj Hall tam sim no sensors muaj qhov zoo ntawm cov qauv yooj yim, tus nqi qis, thiab cov lus teb ceev ceev. Nws muaj qhov zoo xws li kev ceev ceev thiab haum rau lub sijhawm uas xav tau ntau dua ntawm kev ceev thiab tus nqi. Kev xaiv kom raug ntawm qhov tsim nyog tam sim no sensor tuaj yeem ua tau raws li qhov xav tau kev ntsuas tam sim no hauv cov xwm txheej sib txawv.
