Yuav ua li cas txiav txim qhov sib nqus kev ua tau zoo ntawm lub magnetic connector?
Kev ua haujlwm ntawm cov khoom sib nqus dav dav tuaj yeem qhia tau los ntawm nws plaub qhov tsis muaj, uas yog qhov seem sib nqus induction siv (hu ua remanence) Br (unit Gauss Gs lossis mullite mT, 1mT=10Gs), coercivity Hcb (unit Oe), Intrinsic coercivity Hcj ( unit Oe), cov khoom siv hluav taws xob sib nqus siab tshaj plaws (BH) max (unit MGOe), ntawm peb qhov tsis muaj Br, Hcj, (BH) max yog cov lus qhia ncaj qha tshaj plaws.
Kev sib raug zoo ntawm Br, Hcj, (BH) max
Qhov loj ntawm Br feem ntau tuaj yeem txiav txim siab los qhia txog qib ntawm cov hlau nplaum saum npoo tom qab cov hlau nplaum yog magnetized; qhov loj ntawm Hcj tuaj yeem qhia lub peev xwm ntawm cov hlau nplaum tiv thaiv demagnetization thiab kub tsis kam tom qab magnetization; (BH) max yog tus nqi siab tshaj plaws ntawm cov khoom ntawm Br thiab Hcj, Nws qhov loj me ncaj qha qhia qhov ua tau zoo ntawm cov hlau nplaum. Tam sim no, peb tsis tau kuaj pom cov hlau nplaum uas muaj kev sib koom ua ke NdFeB (BH) max zog ntau dua 11.5.
Feem ntau hais lus, rau cov hlau nplaum uas zoo sib xws (BH) max, yog Br siab dua, Hcj qis dua; Yog Hcj siab dua, Br yog qis. Peb tuaj yeem tsis tsuas yog txiav txim siab qhov zoo ntawm cov khoom los ntawm qib ntawm (BH) max tab sis kuj pom tias qib Br thiab Hcj puas haum rau cov khoom peb xav tau.
Kev cuam tshuam ntawm qhov loj ntawm peb ntawm magnetization
Raws li peb txhua tus paub, nyob rau hauv tib txoj kev, uas yog, tib qhov loj, tib tus lej ntawm tus ncej, thiab tib qhov sib nqus hlau nplaum, cov khoom sib nqus nrog cov khoom siv hluav taws xob sib nqus siab tuaj yeem tau txais cov hlau nplaum ntau dua, tab sis tib yam (BH) max tus nqi, Br thiab Hcj Qib ntawm muaj cov teebmeem hauv qab no ntawm magnetization:
Br yog siab, Hcj tsawg: Nyob rau hauv tib lub magnetizing voltage, siab dua nto magnetism yuav tau;
Br yog qis, Hcj siab: Yuav kom tau txais tib qhov chaw magnetization, yuav tsum muaj qhov hluav taws xob ntau dua;
Puas yog qhov loj ntawm peb qhov qhia txog qhov zoo ntawm cov khoom?
Peb tsis tuaj yeem txiav txim siab qhov zoo ntawm Br, Hcj, (BH) max los ntawm qib Br, Hcj, (BH) max, cov tuam txhab hlau nplaum muaj zog txiav txim siab qib peb raws li kev siv cov khoom thiab cov yam ntxwv xav tau; txawm nyob rau hauv tib yam (BH) max tus nqi, Nws kuj nyob ntawm lub hom phiaj ntawm cov khoom thiab cov kev cai rau magnetization txiav txim seb puas yuav siv siab Br thiab qis Hcj los yog vice versa.
Rau ntau tus ncej hlau nplaum yuav tsum siv cov hmoov sib nqus nrog siab Br thiab qis Hcj. Rau cov vuas sib nqus, cov tuam txhab hlau nplaum muaj zog feem ntau siv cov hmoov sib nqus nrog siab Hcj thiab qis Br. Sib nqus tam sim no thiab overload.
