Hamwe niterambere rikomeye ryinganda za elegitoronike, kumenya imyanya yibice bimwe byubaka bigenda bihinduka buhoro buhoro kuva mubipimo byambere byo guhuza kugeza kubipima bidahuza binyuzeImyanya yumwanya wa salle na magnet. Nigute dushobora guhitamo magneti akwiranye n'ibicuruzwa n'imiterere yacu? Hano dukora isesengura ryoroshye.
Ubwa mbere, dukeneye kumenya ibikoresho bya rukuruzi. Kugeza ubu, samarium cobalt magnet na neodymium fer boron ikoreshwa cyane muri sensor ya salle. Itandukaniro nyamukuru hagati ya magnesi zombi nuko ukurikije ingano imwe ya magnet ya NdFeB ikomeye kuruta samarium cobalt; kuzenguruka ubushyuhe bwa samarium cobalt ni nto ugereranije na Nd-Fe-B; okiside irwanya samarium cobalt irakomeye kuruta iya Nd-Fe-B, ariko muri rusange hariho igifuniko hanze ya magneti, gishobora gukemura ikibazo cya okiside; rukuruzi ya samarium cobalt ifite ubukana bwiza kurenza magnet ya NdFeB, ariko agaciro ko kurwanya ubushyuhe kubikoresho byombi bishobora kugera kuri 200 ℃. Kubwibyo, mugihe duhitamo ubwoko bwa magneti, tugomba kubisuzuma duhujwe nigikorwa cyibiciro, ubushyuhe bwakazi hamwe nibidukikije bikora. Muri rusange, NdFeB irashobora gukoreshwa cyane, cyane cyane ko ifite ibyiza bya magnetiki biranga. Ariko, mugihe ukora mubushuhe bugari, birasabwa guhitamo samarium cobalt magnet kubera gutwarwa nubushyuhe buke.
Mubyongeyeho, dukeneye kumenya ibipimo fatizo bya magneti. Dukurikije ikizamini cyimyanya yamakuru hamwe nicyerekezo cyimuka cyikintu, tumenye niba icyerekezo cya magnetisme ya magnet ari diametrical cyangwa axial. Byongeyeho, hamenyekanye niba guhitamo akarecyangwa arukuruziukurikije imiterere yo kwishyiriraho. Birumvikana, rimwe na rimwe dukenera guhitamo imiterere ya rukuruzi dukurikije imiterere. Hariho ikindi kintu gisabwa kubijyanye na magnet flux, yamye nitwe duhangayikishijwe muguhitamo magnet. Mubyukuri, dukeneye kubisesengura mubice bibiri bikurikira:
1.
2. Intera iri hagati ya rukuruzi na sensor ubwayo igenwa nuburyo imiterere yibicuruzwa. Ukurikije ibintu bibiri byavuzwe haruguru hamwe na magnetiki yumurima uhinduranya umurongo mubishushanyo bikurikira nkurugero, turashobora kumenya imbaraga za rukuruzi imbaraga za magneti zisabwa.
Hanyuma, tugomba kumva ko bidasobanuye ko mugihe cyose umurima wa rukuruzi ugwa kumurongo usabwa wa sensor, rukuruzi irashobora kuba kure ya sensor. Nubwo sensor ubwayo ifite imikorere ya kalibrasi, dukeneye kumva ko mugihe magnet ari kure cyane ya sensor, gukwirakwiza umurima wa magneti ubwabyo biragoye kwemeza umurongo cyangwa hafi yumurongo. Ibi bivuze ko hamwe no guhindura imyanya no gukwirakwiza umurongo wa magnetiki ubwayo, gupima sensor bizaba bigoye kandi na kalibrasi bizaba bigoye cyane, kugirango ibicuruzwa bitagabanuka.
Ibyavuzwe haruguru ni isesengura ryoroshye ryo guhitamo magnet muri porogaramu ya sensor ya Hall. Turizera ko bizagufasha. Niba ufite ibindi bibazo mugihe cyiterambere, nyamuneka twandikire,Ningbo Horizon Magnetics. Turashobora gukora itumanaho kandi tukaguha inkunga ya tekiniki.
