N35 vs N52: Qhov Magnet Qib twg yog qhov zoo tshaj rau koj tus qauv tsim?

U-shaped neodymium hlau nplaum muaj qhov sib nqus sib nqus tsis sib haum, tab sis xaiv cov qib zoo tshaj plaws, xws li N35 nrov thiab muaj zog N52, yog qhov tseem ceeb rau kev ntsuas kev ua tau zoo, ua haujlwm ntev, thiab tus nqi. Thaum N52 theoretically muaj zog sib nqus ntau dua, nws qhov zoo yuav raug cuam tshuam los ntawm qhov tshwj xeeb xav tau ntawm U-shaped geometry. Kev nkag siab txog cov kev lag luam tawm no ua kom koj tus qauv tsim ua tiav nws cov hom phiaj kev ua tau zoo sib nqus thiab kev lag luam.

Qhov txawv ntawm Core: Sib Nqus Lub Zog vs. Brittleness

N52:Sawv cev rauqib siab tshaj uas nquag sivhauv N series. Nws muaj cov khoom siv hluav taws xob siab tshaj plaws (BHmax), remanence (Br), thiab coercivity (HcJ),siab tshaj rub quab yuam achievable rau ib tug muab loj.Xav raw magnetic quab yuam.

N35: A qis zog, tab sis qib kev lag luam ntau dua.Thaum nws cov khoom siv hlau nplaum qis dua li ntawm N52, nws feem ntau muajzoo dua mechanical toughness thiab siab dua rau kev tawg.Nws tseem tuaj yeem tiv taus qhov kub thiab txias ua ntej irreversible poob ntawm lub zog.

Vim li cas U-Shape Hloov Cov Kev Ua Si

Lub iconic U-puab tsis yog tsuas yog hais txog magnetic teb tsom, nws kuj coj ntau yam kev cov nyom:

Inherent stress concentration:Lub ntse ntse sab hauv ntawm U-puab yog qhov chaw muaj kev ntxhov siab ntuj, ua rau nws muaj kev cuam tshuam rau kev tawg.

Manufacturing complexity:Sintering thiab machining tsis yooj yim neodymium rau hauv cov duab no ua rau muaj kev pheej hmoo ntawm kev puas tsuaj piv rau cov txheej txheem yooj yim los yog disc.

Sib tw Magnetization:Nyob rau hauv ib tug U-puab, ua tiav tag nrho cov sib nqus sib nqus saturation ntawm tus ncej ntawm lub ntsej muag (kawg ntawm tus pins) yuav nyuaj dua, tshwj xeeb tshaj yog nyob rau hauv high-flux, nyuaj-rau-tsav qib.

Thermal demagnetization Risk:Hauv qee qhov kev siv (xws li lub cev muaj zog), qhov chaw sib nqus tsom thiab kev ua haujlwm siab dua tuaj yeem ua rau lawv tsis muaj zog.

U-Shaped Magnets N35 vs. N52: Cov Ntsiab Lus Tseem Ceeb

Yuav Tsum Muaj Zog Muaj Zog:

Xaiv N52 IF:Koj tus qauv tsim kiag li yog nyob ntawm kev nyem txhua qhov tshiab ntawm rub los ntawm qhov tsawg tshaj plaws U-zoo li tus hlau nplaum, thiab koj muaj cov txheej txheem tsim / tsim kom muaj kev pheej hmoo. N52 excels qhov siab tshaj qhov sib txawv ntawm qhov ntom ntom tsis muaj kev txhawj xeeb (xws li chucks tseem ceeb, kev ua haujlwm siab micromotors).

Xaiv N35 IF:N35 muaj zog txaus rau koj daim ntawv thov. Feem ntau, qhov loj me me N35 U-zoo li tus hlau nplaum yuav muaj kev ntseeg siab thiab kev lag luam raws li qhov xav tau rub quab yuam dua li N52 brittle. Tsis txhob them rau lub zog koj siv tsis tau.

Risk of Fracture thiab Durability:

Xaiv N35 IF:Koj daim ntawv thov cuam tshuam nrog kev poob siab, kev vibration, flexing, los yog nruj mechanical sib dhos. Qhov zoo tshaj plaws pob txha toughness ntawm N35 txo qhov kev pheej hmoo ntawm cov hlau nplaum tawg, tshwj xeeb tshaj yog nyob rau hauv qhov tseem ceeb sab hauv khoov. N52 yog nkig heev thiab muaj kev cuam tshuam rau kev tawg lossis kev puas tsuaj loj yog tias ua haujlwm tsis raug lossis ntxhov siab.

Xaiv N52 IF:Cov hlau nplaum muaj kev tiv thaiv zoo heev thaum lub sij hawm sib dhos, kev ntxhov siab ntawm cov neeg kho tshuab yog tsawg, thiab cov txheej txheem tuav tau nruj nruj. Txawm li cas los xij, qhov dav dav sab hauv txoj kab uas hla tsis tuaj yeem sib cav.

Ua haujlwm kub:

Xaiv N35 IF:Koj cov hlau nplaum ua haujlwm ntawm qhov kub thiab txias tshaj 80 ° C (176 ° F). N35 muaj qhov kub siab tshaj qhov ua haujlwm siab (feem ntau yog 120 ° C vs. 80 ° C rau N52), saum toj no qhov kev poob tsis tuaj yeem tshwm sim. N52 lub zog txo qis dua nrog nce kub. Qhov no yog qhov tseem ceeb hauv U-zoo li cov cua sov-concentrating qauv.

Xaiv N52 IF:ambient kub tsis tu ncua (tsawg dua 60-70 ° C) thiab chav tsev kub siab tshaj plaws yog qhov tseem ceeb.

Nqi & Manufacturability:

Xaiv N35 IF:Tus nqi yog qhov kev txiav txim siab loj. N35 nqi tsawg dua ib kg dua N52. Cov qauv U-shaped complex kuj feem ntau ua rau cov khoom seem ntau dua thaum lub sij hawm sintering thiab ua, tshwj xeeb tshaj yog rau cov nkig ntau N52, uas ntxiv rau nws cov nqi tiag tiag. N35 cov khoom ua kom zoo dua tuaj yeem nce yield.

Xaiv N52 IF:Cov txiaj ntsig kev ua tau zoo ua rau nws tus nqi siab dua thiab muaj peev xwm tawm los poob tsim nyog, thiab daim ntawv thov tuaj yeem nqus cov nqi siab dua.

Magnetization & Stability:

Xaiv N35 IF:Koj cov khoom siv magnetizing muaj tsawg zog. N35 yooj yim dua rau kev sib nqus tag nrho tshaj N52. Txawm hais tias ob qho tib si tuaj yeem sib nqus tau tag nrho, cov hlau nplaum tsis sib xws hauv U-shaped geometry tej zaum yuav ua tau zoo dua nrog N35.

Xaiv N52 IF:Koj muaj peev xwm nkag tau mus rau qhov muaj zog magnetizing fixture muaj peev xwm ntawm tag nrho magnetizing siab coercivity N52 qib nyob rau hauv ib tug U-shaped txwv. Xyuas kom meej tias tag nrho cov ncej saturation tiav.

Qhov "muaj zog tsis tas yuav zoo dua" qhov tseeb rau U-shaped hlau nplaum

Pushing N52 hlau nplaum nyuaj hauv U-shaped designs feem ntau ua rau txo qis rov qab:

Tus nqi ntawm kev tawg: Lub hlau nplaum N52 tawg raug nqi ntau dua li cov hlau nplaum ua haujlwm N35.

Thermal txwv: Lub zog ntxiv sai sai ploj yog tias qhov kub nce.

Over-engineering: Tej zaum koj yuav tau them nyiaj ntxiv rau lub zog uas koj tsis tuaj yeem siv tau zoo vim yog cov duab geometry lossis kev sib dhos.

Cov Txheej Txheem Txheej Txheem: Tiv thaiv cov hlau nplaum N52 nkig ntau dua, tshwj xeeb tshaj yog nyob rau hauv qhov muag muag sab hauv khoov, yog qhov tseem ceeb, tab sis qhov no ntxiv qhov nyuaj / nqi.
