Tam sim no, muaj peb hom tseem ceeb ntawm cov hlau nplaum hais lus hauv khw: AlNiCo, ferrite thiab neodymium hlau boron. Alnico yog cov hlau nplaum ntxov tshaj plaws siv hauv cov neeg hais lus. Piv txwv li, lub suab raj tshuab raj hauv xyoo 1950 thiab 1960s feem ntau yog ua los ntawm lub tshuab raj sab hauv. Qhov tsis zoo yog lub zog me me, qhov ntau zaus yog qhov nqaim, AlNiCo horn hlau nplaum yog qhov nyuaj thiab nkig heev, thiab nws tsis yooj yim rau txheej txheem. Tus nqi yog tus siab vim tias cobalt yog cov peev txheej tsis txaus. Yog li ntawd, lub raj hlau nplaum xaiv tsawg dua AlNiCo. Kev ua tau zoo ntawm ferrite horn hlau nplaum yog qhov tsawg, thiab nws xav tau qee qhov ntim kom tau raws li kev tsav tsheb ntawm lub suab raj. Feem ntau, nws yog ua los ntawm lub suab sib nqus sab nraud, yog li nws feem ntau yog siv hauv lub suab nrov loj dua. Qhov zoo ntawm cov hlau nplaum ferrite yog tias lawv pheej yig thiab raug nqi; lawv qhov tsis zoo yog tias cov hlau nplaum loj dua qhov loj me, lub zog me dua, thiab nqaim hauv ntau zaus. Cov khoom sib nqus ntawm NdFeB cov hlau nplaum yog qhov zoo tshaj rau AlNiCo thiab ferrite. Tam sim no lawv feem ntau yog siv cov hlau nplaum hauv cov hais lus suab, tshwj xeeb yog cov chav hais lus siab. Meirui hais lus Hoobkas feem ntau tsim cov hom ntawm cov neeg hais lus. Nws qhov zoo yog nws qhov me me, lub zog muaj zog thiab ntau qhov sib txawv nyob hauv tib lub zog sib nqus. Qhov tsis zoo yog tias nws muaj cov khoom hauv ntiaj teb tsis tshua muaj, yog li cov khoom siv tus nqi kuj siab.
Thaum xaiv lub tshuab raj, nws tseem yuav tsum tau txiav txim siab yam cuam tshuam rau kev ua haujlwm ntawm lub tshuab raj hlau nplaum hlau. Ua ntej tshaj plaws, peb yuav tsum txiav txim siab qhov chaw ua haujlwm kub ntawm tus neeg hais lus thiab xaiv cov hlau nplaum tsim nyog rau tus hais lus.
Sib txawv horn sib nqus hlau hlau nplaum muaj cov yam ntxwv sib txawv ntawm qhov kub tsis kam, thiab qhov siab tshaj plaws ua haujlwm kub uas tuaj yeem txhawb nqa kuj txawv. Thaum qhov chaw ua haujlwm kub ntawm tus neeg hais lus tshaj qhov kub siab tshaj ntawm cov hlau nplaum, qhov ua tau zoo ntawm cov hlau nplaum tuaj yeem ua rau qis thiab txo qis, uas yuav cuam tshuam ncaj qha rau lub suab nrov ntawm tus hais lus. Kub tiv taus: AlNiCo> Ferrite> NdFeB. Qhov thib ob, nws yog qhov yuav tsum tau ua tib zoo xav txog qhov xav tau ntawm cov hlau nplaum thiab qhov ntim ntawm cov hlau nplaum los xaiv lub tshuab raj hlau. Kev sib nqus ntawm cov hlau nplaum muaj qhov cuam tshuam zoo rau lub suab zoo ntawm lub suab. Nyob rau hauv rooj plaub ntawm tib lub ntim, qhov ua tau zoo ntawm cov hlau nplaum: NdFeB> AlNiCo> Ferrite; Raws li qhov yuav tsum tau ua kom sib nqus sib nqus, NdFeB hlau nplaum yuav tsum tau ntim tsawg tshaj plaws, thiab ferrite Lub cev loj tshaj plaws. Cov khoom siv sib nqus zoo ib yam, qhov loj dua txoj kab uas hla, ntau dua qhov sib nqus ntawm qhov sib nqus, ntau zog ntawm tus hais lus, siab dua qhov ua tau zoo ntawm tus hais lus, thiab zoo dua qhov kev teb sai. Yog li ntawd, nws yog qhov yuav tsum tau ua tib zoo xav txog qhov txwv ntawm lub suab ntawm lub suab ntawm lub ntim ntawm cov hlau nplaum thiab qhov yuav tsum tau ua ntawm kev sib nqus flux kev ua tau zoo ntawm cov hlau nplaum los txiav txim seb lub tshuab raj hlau twg xaiv.
