Nekukura kwakasimba kweindasitiri yemagetsi, kutariswa kwenzvimbo kwezvimwe zvimiro zvishoma nezvishoma kunoshanduka kubva pachiyero chekutanga chekusangana kuenda kune isiri-yekubata kuyerwa kuburikidza.Hall chinzvimbo sensor uye magineti.Tingasarudza sei magineti akakodzera zvinoenderana nezvigadzirwa zvedu uye chimiro?Pano tinoita kumwe kuongorora kuri nyore.
Chokutanga, tinofanira kuziva magineti zvinhu.Parizvino, samarium cobalt magineti uye neodymium iron boron inoshandiswa zvakanyanya muhoro chinzvimbo sensor.Musiyano mukuru pakati pemagineti maviri ndewekuti zvichienderana nevhoriyamu imwechete NdFeB magineti yakasimba kupfuura samarium cobalt magineti;iyo thermal excursion yesamarium cobalt idiki pane iyo yeNd-Fe-B;iyo oxidation resistance yesamarium cobalt yakasimba kudarika iyo yeNd-Fe-B, asi kazhinji pane chifukidziro kunze kwemagineti, chinogona kugadzirisa dambudziko re oxidation;iyo samarium cobalt magineti ine zvirinani tembiricha kuramba kupfuura NdFeB magineti, asi tembiricha yekudzivirira kukosha kune ese magineti zvinhu zvinogona kusvika kupfuura 200 ℃.Naizvozvo, pakusarudza rudzi rwemagineti, isu tinofanirwa kuiongorora mukubatana nemutengo wekuita, tembiricha yekushanda uye nharaunda yekushanda.Kazhinji, NdFeB inogona kushandiswa zvakanyanya, kunyanya nekuti ine yakanakisa magineti maitiro.Nekudaro, kana uchishanda mune yakafara tembiricha renji, zvinokurudzirwa kusarudza samarium cobalt magineti nekuda kweiyo diki yekudziya kwayo.
Uye zvakare, isu tinofanirwa kuona mamwe magineti akakosha paramita.Zvinoenderana neruzivo rwenzvimbo yekuyedza uye mafambiro echinhu, isu tinoona kana iyo magnetization nzira yegineti iri diametric kana axial.Pamusoro pezvo, zvinotariswa kana kusarudza asquare maginetikana ahumburumbira maginetimaererano nekugadzirisa maitiro.Ehe, dzimwe nguva tinoda kugadzirisa chimiro chemagneti zvinoenderana nechimiro.Pane chimwe chinhu chinodiwa nezve magineti flux, yagara iri hanya yedu pakusarudza magineti.Muchokwadi, isu tinofanirwa kuiongorora muzvikamu zviviri zvinotevera:
1. Simba remagineti rinokonzereswa neiyo horo chinzvimbo sensor pachayo uye induced magineti renji munzira yega yega ichave yakanyatso cherechedzwa mubhuku re data sensor.
2. Kureba pakati pemagineti uye sensor pachayo kunowanzo kutsanangurwa nechigadzirwa chimiro.Zvinoenderana nezviri pamusoro pezvinhu zviviri zviri pamusoro uye magineti shanduko yekuchinja mumufananidzo uri pazasi semuenzaniso, tinogona kuona iyo magineti simba remagineti inodiwa.
Chekupedzisira, isu tinofanirwa kunzwisisa kuti hazvireve kuti chero bedzi iyo magineti inowira pane yakasarudzika zvinodiwa zve sensor, magineti anogona kunge ari kure kure ne sensor.Kunyangwe iyo sensor pachayo iine calibration basa, isu tinofanirwa kunzwisisa kuti kana magineti iri kure zvakanyanya kubva kune sensor, kugovera kweiyo magineti pachayo kwakaoma kuve nechokwadi mutsara kana padyo nemutsara.Izvi zvinoreva kuti nekuchinja kwechinzvimbo uye kugovera kusingaenzaniswi kwemagnetic field pachayo, chiyero che sensor chichava chakaoma uye kuenzanisa kuchave kwakaoma zvikuru, kuitira kuti chigadzirwa hachina reducibility.
Izvo zviri pamusoro ingori ongororo yakapusa yekusarudza magineti muHall sensor application.Tinovimba zvichabatsira kwauri.Kana uine mimwe mibvunzo panguva yekuvandudza, ndapota taura nesu,Ningbo Horizon Magnetics.Tinogona kuita kumwe kutaurirana uye kukupa iwe nerutsigiro rwehunyanzvi.
