Ngokobume bento ebhaqiweyo, usetyenziso lwabo lweMagnetic Hall effect sensor inokwahlulwa ibe sisicelo esithe ngqo kunye nesicelo esingathanga ngqo.Owokuqala kukubona ngokuthe ngqo intsimi yamagnetic okanye iimpawu zemagneti zento evavanyiweyo, kwaye okokugqibela kukufumanisa i-artificially set magnetic field kwinto evavanyiweyo.Lo mmandla wemagnethi ngumthwali wolwazi olufunyenweyo.Ngayo, uninzi lwezinto ezingezizo zombane kunye nezingezizo ezemagneti, njengesantya, isantya, i-engile, isantya se-angular, iirevolutions, isantya sokujikeleza kunye nexesha apho utshintsho lwemeko yokusebenza luguqulwa lube ngumbane wokubhaqwa kunye nokulawula.
Izinzwa zempembelelo zeholo zihlulwe zibe ziintlobo zedijithali kunye ne-analog esekelwe kwisignali yokuphuma.
Umbane ophumayo wemveliso yedijithali Izivamvo zempembelelo zeholo zinobudlelwane bomgca kunye nobunzulu bomhlaba osetyenziswayo.
Isiphumo se-analog yesiphumo se-Hall sensor sinento yeHolo, iamplifier yomgca kunye nomlandeli we-emitter, ovelisa ubuninzi be-analog.
Umlinganiselo wokufuduswa
Oomazibuthe ababini abasisigxina bathandaNeodymium Magnetszibekwe kunye polarity efanayo.I-digital Hall sensor ibekwe embindini, kwaye amandla ayo okufakelwa kwamagnetic ngu-zero.Le ndawo ingasetyenziswa njengendawo enguziro yokufuduswa.Xa i-sensor yeholo yenza i-displacement, i-sensor ine-voltage output, kwaye i-voltage ihambelana ngokuthe ngqo kwi-displacement.
Umlinganiselo wokunyanzeliswa
Ukuba iiparameters ezifana noxinzelelo kunye noxinzelelo zitshintshwa zibe yi-displacement, ubukhulu boxinzelelo kunye noxinzelelo lunokulinganiswa.Ngokwalo mgaqo, i-sensor yamandla inokwenziwa.
iAngular Velocity Measurement
Namathisela iqhekeza lentsimbi yamagnetic emphethweni wediski yezinto ezingezizo-magnetic, beka isivamvo seholo kufutshane nomphetho wediski, ujikelezise idiski kumjikelo omnye, iholo loluvo lukhupha ipulse, ukuze inani leenguquko (revolutions) counter) inokulinganiswa.Ukuba i-frequency meter ixhunyiwe, isantya sinokulinganiswa.
Umlinganiselo wesantya somgca
Ukuba i-sensor yeHolo yokutshintsha icwangciswa rhoqo kumzila ngokwendawo echazwe kwangaphambili, umqondiso we-pulse unokulinganiswa ukusuka kwisekethe yokulinganisa xa umazibuthe osisigxina ethanda.Samarium Cobaltefakwe kwisithuthi esihambayo sidlula kuyo.Isantya esihambayo sesithuthi sinokulinganiswa ngokusasazwa komqondiso we-pulse.
Ukusetyenziswa kweTekhnoloji yeSensor yeHolo kuShishino lweemoto
Itekhnoloji yesivamvo seHolo isetyenziswa kakhulu kwishishini leemoto, kubandakanya amandla, ulawulo lomzimba, ulawulo lokutsala kunye nenkqubo yokunqanda ukutshixa.
Ifom ye-sensor yeHolo imisela umahluko wesiphaluka sokukhulisa, kwaye umphumo wayo kufuneka ulungelelanise nesixhobo esilawulwayo.Le mveliso inokuba yi-analog, njengesixhobo soluvo lwendawo yokukhawulezisa okanye isivamvo sendawo ye-throttle;okanye idijithali, njenge-crankshaft okanye i-camshaft position sensor.
Xa iHolo element isetyenziselwa i-analog sensor, le nzwa ingasetyenziselwa i-thermometer kwinkqubo yomoya okanye i-throttle position sensor kwinkqubo yokulawula amandla.Iholo yeholo idibaniswe ne-amplifier ehlukeneyo, kwaye i-amplifier idibene ne-NPN transistor.Umazibuthe osisigxinaNdFeB or SmCoigxininiswe kwi-shaft ejikelezayo.Xa i-shaft ijikeleza, intsimi yamagnetic kwi-holo yeholo iqiniswa.Umbane weHolo owenziweyo ulingana namandla emagnethi.
Xa indawo yeholo isetyenziselwa iimpawu zedijithali, ezifana ne-crankshaft position sensor, i-camshaft position sensor okanye i-speed sensor yesithuthi, isiphaluka kufuneka sitshintshwe kuqala.Iholo yeholo idibaniswe ne-amplifier yokwahlukana, edibaniswa ne-trigger ye-Schmidt.Kolu qwalaselo umenzi woluvo ukhupha isignali yokuvula okanye yokuvala.Kwiisekethe ezininzi zeemoto, ii-Sensors zeHolo zi-absorber zangoku okanye iisekethe zesignali zomhlaba.Ukugqiba lo msebenzi, i-NPN Transistor kufuneka idibaniswe nemveliso ye-Schmitt trigger.Umhlaba wemagnethi udlula kwindawo yeholo, kwaye iblade ekwivili lokudubula idlula phakathi kwemagnethi kunye neholo yeholo.
