Nrog rau txoj kev loj hlob ntawm kev lag luam hauv hluav taws xob, txoj hauj lwm nrhiav pom ntawm qee cov qauv tsim maj mam hloov pauv los ntawm qhov kev ntsuas kev sib cuag mus rau qhov ntsuas tsis sib cuag los ntawmHall txoj hauj lwm sensor thiab hlau nplaum. Peb tuaj yeem xaiv cov hlau nplaum tsim nyog raws li peb cov khoom thiab cov qauv? Ntawm no peb ua qee qhov kev ntsuam xyuas yooj yim.
Ua ntej, peb yuav tsum txiav txim siab cov khoom siv hlau nplaum. Tam sim no, samarium cobalt hlau nplaum thiab neodymium hlau boron yog dav siv nyob rau hauv txoj hauj lwm sensor. Qhov sib txawv tseem ceeb ntawm ob lub hlau nplaum yog tias raws li tib lub ntim NdFeB hlau nplaum muaj zog dua samarium cobalt hlau nplaum; thermal excursion ntawm samarium cobalt yog me dua li ntawm Nd-Fe-B; oxidation tsis kam ntawm samarium cobalt muaj zog dua li ntawm Nd-Fe-B, tab sis feem ntau muaj txheej txheej sab nraud ntawm cov hlau nplaum, uas tuaj yeem daws qhov teeb meem ntawm oxidation; cov hlau nplaum samarium cobalt muaj qhov kub zoo dua li NdFeB hlau nplaum, tab sis qhov ntsuas kub tsis kam rau cov khoom siv hlau nplaum tuaj yeem ncav cuag ntau dua 200 ℃. Yog li ntawd, thaum xaiv hom hlau nplaum, peb yuav tsum ntsuas nws ua ke nrog cov nqi kev ua haujlwm, kev ua haujlwm kub thiab qhov chaw ua haujlwm. Feem ntau, NdFeB tuaj yeem siv ntau dua, feem ntau vim tias nws muaj cov yam ntxwv zoo tshaj plaws sib nqus. Txawm li cas los xij, thaum ua haujlwm nyob rau hauv ntau qhov kub thiab txias, nws raug nquahu kom xaiv samarium cobalt hlau nplaum vim nws cov thermal drift me me.
Tsis tas li ntawd, peb yuav tsum tau txiav txim siab qee qhov tsis tseem ceeb ntawm cov hlau nplaum. Raws li cov ntaub ntawv xeem txoj hauj lwm thiab kev txav ntawm cov khoom, peb txiav txim siab seb qhov kev taw qhia ntawm cov hlau nplaum yog diametrical lossis axial. Tsis tas li ntawd, nws txiav txim siab seb yuav xaiv ib qho twgsquare hlau nplaumlos yog alub tog raj kheej hlau nplaumraws li tus qauv installation. Tau kawg, qee zaum peb yuav tsum tau kho cov duab ntawm cov hlau nplaum raws li cov qauv. Muaj lwm qhov tseem ceeb ntawm qhov xav tau ntawm cov hlau nplaum flux, uas ib txwm ua rau peb txhawj xeeb hauv kev xaiv hlau nplaum. Qhov tseeb, peb yuav tsum txheeb xyuas nws hauv ob yam hauv qab no:
1. Lub zog magnetic teb induced los ntawm lub Hall txoj hauj lwm sensor nws tus kheej thiab induced magnetic teb ntau yam nyob rau hauv txhua qhov kev taw qhia yuav raug cim kom meej meej nyob rau hauv cov ntaub ntawv sensor phau ntawv.
2. Qhov kev ncua deb ntawm cov hlau nplaum thiab lub sensor nws tus kheej feem ntau txiav txim siab los ntawm cov qauv khoom. Raws li ob qho tib si saum toj no thiab cov hlau nplaum hloov pauv nkhaus hauv daim duab hauv qab no ua piv txwv, peb tuaj yeem txiav txim siab lub zog sib nqus ntawm cov hlau nplaum uas yuav tsum tau muaj.
Thaum kawg, peb yuav tsum tau nkag siab tias nws tsis txhais hais tias ntev npaum li qhov chaw sib nqus poob ntawm qhov kev xav tau ntawm lub sensor, cov hlau nplaum tuaj yeem nyob deb ntawm lub sensor. Txawm hais tias lub sensor nws tus kheej muaj calibration muaj nuj nqi, peb yuav tsum to taub hais tias thaum lub hlau nplaum nyob deb dhau ntawm lub sensor, qhov kev faib ntawm cov hlau nplaum nws tus kheej yog ib qho nyuaj los xyuas kom meej linearity los yog ze rau linearity. Qhov no txhais tau hais tias nrog kev hloov ntawm txoj hauj lwm thiab cov nonlinear tis ntawm lub magnetic teb nws tus kheej, lub sensor ntsuas yuav complex thiab lub calibration yuav ua complex, yog li ntawd cov khoom tsis muaj reducibility.
Cov saum toj no tsuas yog ib qho yooj yim tsom xam ntawm cov hlau nplaum xaiv hauv Hall sensor daim ntawv thov. Peb vam tias nws yuav pab tau koj. Yog tias koj muaj lwm yam lus nug thaum lub sijhawm txhim kho, thov hu rau peb,Ningbo Horizon Magnetics. Peb tuaj yeem ua kev sib txuas lus ntxiv thiab muab kev txhawb nqa rau koj.
