Ib Sab vs Ob Sab vs 2 hauv 1 Magnet: Dab tsi zoo dua?

Cia peb txiav txim siab mus rau qhov kev sib tw:Thaum nws los txog rau cov hlau nplaum neodymium, ib qhov loj me (lossis ib hom) TSIS haum rau txhua tus. Kuv tau siv ntau xyoo los pab cov khw muag khoom, cov chaw tsim khoom, thiab cov neeg nyiam ua si xaiv cov hlau nplaum zoo rau txoj haujlwm - tsuas yog saib lawv pov tseg nyiaj rau qhov kev xaiv "ci ntsa iab tshaj plaws" es tsis yog qhov uas ua haujlwm tiag tiag. Niaj hnub no, peb tab tom rhuav tshem peb hom hlau nplaum nrov: ib sab, ob sab (yog, qhov ntawd suav nrog cov hlau nplaum neodymium ob sab), thiab 2 hauv 1 hlau nplaum. Thaum kawg, koj yuav paub meej tias qhov twg tsim nyog rau hauv koj cov cuab yeej.

Ua ntej, Cia peb nkag siab meej txog txhua yam style

Ua ntej peb yuav tham txog qhov "qhov twg zoo dua," cia peb xav txog tib yam. Tsis txhob siv cov lus tsis zoo - tsuas yog tham txog txhua lub hlau nplaum ua dab tsi, thiab vim li cas nws thiaj tseem ceeb.

Cov Hlau Nplaum Ib Sab: Cov Ntsiab Lus Tseem Ceeb ntawm Workhorse

Cov hlau nplaum ib sab yog raws nraim li lawv lub suab zoo li: tag nrho lawv lub zog sib nqus yog tsom mus rau ib qho chaw tseem ceeb, nrog rau lwm sab (thiab nraub qaum) tsim los kom muaj kev rub tsawg kawg nkaus. Xav txog koj tus qauv tuav cov cuab yeej sib nqus lossis lub tub yees hlau nplaum (txawm hais tias cov hlau nplaum neodymium ib sab kev lag luam ntim ntau dua). Lawv feem ntau yog khub nrog lub phaj nraub qaum uas tsis yog hlau nplaum los tsom cov flux rau sab ua haujlwm, tiv thaiv kev rub tsis xav tau rau cov hlau nyob ze.

Kuv muaj ib tug neeg siv khoom uas siv cov hlau nplaum ib sab los tuav cov hlau thaum vuam. Thaum xub thawj, lawv yws txog "qhov tsis muaj zog" - txog thaum peb paub tias lawv tau teeb tsa lawv rov qab, siv sab uas tsis yog hlau nplaum. Qhov tseem ceeb? Cov hlau nplaum ib sab yooj yim, tab sis koj yuav tsum hwm lawv txoj kev tsim uas muaj ib sab.

Ob Chav Sided Neodymium MagnetsKev Siv Tau Ob Sab:

Tam sim no, cia peb tham txog cov hlau nplaum neodymium ob sab - tus phab ej tsis muaj npe nrov rau cov ntawv thov uas xav tau kev sib cuam tshuam ntawm hlau nplaum ntawm ob sab. Cov hlau nplaum NdFeB tshwj xeeb no tau tsim los xa cov kev nyiam lossis kev thawb tawm ntawm ob qhov chaw tshwj xeeb, thaum tswj kom tsawg kawg nkaus ntawm sab xau (feem ntau nrog cov khoom siv tsis yog hlau nplaum ntawm ntug). Tsis zoo li cov hlau nplaum ib sab, lawv tsis yuam koj xaiv "pem hauv ntej" lossis "rov qab" - lawv ua haujlwm ntawm ob sab.

Muaj ob hom tseem ceeb: tus ncej sab nraud (sab qaum teb ntawm ib sab, sab qab teb ntawm lwm sab) rau kev tuav ob lub khoom hlau ua ke, thiab tus ncej tib yam (sab qaum teb-sab qaum teb lossis sab qab teb-sab qab teb) rau kev xav tau kev thawb xws li levitation lossis buffering. Kuv pom zoo kom siv cov hlau nplaum neodymium ob sab uas muaj tus ncej sab nraud rau tus neeg siv khoom ntim khoom xyoo tas los - lawv tau hloov cov kua nplaum thiab cov staples rau kev kaw lub thawv khoom plig, txiav lub sijhawm sib dhos los ntawm 30% thiab ua rau cov thawv rov siv tau dua. Yeej-yeej.

Lub tswv yim zoo: Cov hlau nplaum neodymium ob sab khaws tag nrho cov txiaj ntsig tseem ceeb ntawm NdFeB—cov khoom muaj zog siab, muaj zog coercivity, thiab me me—tab sis lawv tus qauv tsim ob-ncej ua rau lawv tsis muaj txiaj ntsig rau cov haujlwm ib sab. Tsis txhob siv lawv ua kom nyuaj dhau qhov twg cov hlau nplaum ib sab yuav ua tau.

2 hauv 1 Cov Hlau nplaum: Tus Sib Tw Sib Xyaws

2 hauv 1 cov hlau nplaum (tseem hu ua cov hlau nplaum hloov tau) yog cov chameleons ntawm pawg. Lawv cia koj hloov ntawm ib sab thiab ob sab kev ua haujlwm, feem ntau nrog lub tiv thaiv tsis muaj hlau nplaum lossis slider txav tau. Txav lub tiv thaiv ib txoj kev, thiab tsuas yog ib sab ua haujlwm; txav nws mus rau lwm qhov, thiab ob sab ua haujlwm. Lawv tau tshaj tawm tias yog "txhua yam-hauv-ib qho", tab sis kuv tau pom tias lawv yog kev pauv pauv - koj tau txais kev hloov pauv, tab sis poob me ntsis ntawm lub zog raw piv rau cov kev xaiv ib sab lossis ob sab.

Ib tug neeg siv khoom hauv kev tsim kho tau sim siv cov hlau nplaum 2 hauv 1 rau kev teeb tsa cov paib ib ntus. Lawv ua haujlwm rau cov paib sab hauv tsev, tab sis thaum raug cua thiab kev co, lub slider yuav txav mus, ua rau ib sab tsis ua haujlwm. Rau kev siv ruaj khov thiab siv tau ntev, cov hlau nplaum tshwj xeeb tseem yeej - tab sis 2 hauv 1 ci rau cov haujlwm sai thiab hloov pauv tau.

Lub Taub Hau Mus Rau Lub Taub Hau: Qhov Twg Yog Qhov Zoo Rau Koj?

Cia peb piav qhia txog cov yam tseem ceeb uas tseem ceeb - lub zog rub, kev siv tau, tus nqi, thiab kev ua tau zoo hauv lub ntiaj teb tiag tiag - yog li koj thiaj li tsis txhob kwv yees ntxiv lawm.

Lub zog rub thiab kev ua haujlwm zoo

Cov hlau nplaum ib sab yeej rau qhov muaj zog raw, tsom mus rau ib qho chaw. Vim tias txhua qhov flux raug coj mus rau ib qho chaw, lawv xa ntau dua rub ib cubic inch dua li 2 hauv 1s, thiab feem ntau ua tau zoo dua ob sab neodymium hlau nplaum hauv ib txoj haujlwm. Ob sab neodymium hlau nplaum faib flux ntawm ob qho chaw, yog li lawv lub zog ib sab qis dua - tab sis lawv tsis muaj zog thaum koj xav tau ob-kev ua. 2 hauv 1s yog qhov tsis muaj zog tshaj plaws ntawm peb, vim tias lub tshuab tiv thaiv ntxiv qhov loj thiab txo qhov ceev ntawm flux.

Kev Siv Tau & Kev Haum Rau Daim Ntawv Thov

Ib sab xwb: Zoo tagnrho rau kev teeb tsa cov cuab yeej, cov paib, lossis cov khoom uas koj tsuas xav tau qhov rub rau ib qho chaw xwb. Zoo heev rau kev vuam, ua haujlwm ntoo, lossis khw muag tsheb - txhua qhov chaw uas qhov rub sab tsis xav tau yog qhov teeb meem.

Neodymium ob sab: Zoo meej rau kev ntim khoom (cov hlau nplaum kaw), cov khoom siv hluav taws xob (micro-sensors, cov motors me me), lossis cov haujlwm sib dhos uas xav tau kev sib txuas ob qho hlau yam tsis muaj cov khoom siv txuas. Lawv kuj yog qhov xaiv zoo tshaj plaws rau cov khoom siv hauv tsev ntse xws li cov hlau nplaum qhov rooj lossis cov khoom siv hauv chav dej.

2 hauv 1: Zoo tshaj plaws rau cov neeg nyiam ua si, cov neeg ua haujlwm txav chaw, lossis cov haujlwm tsis muaj kev ntxhov siab uas koj xav tau kev ywj pheej. Xav txog kev nthuav qhia kev lag luam (hloov ntawm kev teeb tsa ib sab thiab kev tuav ob sab) lossis DIY tej yaam num nrog kev xav tau sib txawv.

Tus nqi thiab kev ruaj khov

Cov hlau nplaum ib sab yog cov uas pheej yig tshaj plaws—tsim yooj yim, tus nqi tsim khoom qis. Cov hlau nplaum neodymium ob sab raug nqi ntau dua 15-30% vim yog kev sib nqus meej thiab cov ntaub ntawv substrate, tab sis lawv tsim nyog rau cov ntawv thov tshwj xeeb. Cov hlau nplaum 2 hauv 1 yog cov kim tshaj plaws, ua tsaug rau lawv cov khoom txav mus los—thiab cov khoom ntawd yooj yim hnav dhau sijhawm, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav (xav txog noo noo, plua plav, lossis kub heev).

Nco ntsoov: Kub yog qhov tua ntsiag to rau txhua lub hlau nplaum neodymium. Cov hlau nplaum neodymium ob sab txheem tuaj yeem ua haujlwm txog li 80 ° C (176 ° F); yog tias koj siv lawv ze ntawm qhov chaw vuam lossis chaw nres tsheb cav, caij nplooj ntoos hlav rau cov qib kub siab. Cov hlau nplaum ib sab muaj cov kev txwv kub zoo sib xws, thaum 2 hauv 1s tuaj yeem ua haujlwm sai dua hauv cua sov vim lawv cov khoom yas.

Kev Txiav Txim: Tsum Tsis Txhob Nrhiav "Tus Zoo Tshaj Plaws" - Xaiv Tus Yog

Tsis muaj ib yam dab tsi uas yuav ua rau koj zoo siab tag nrho—tsuas yog ib yam uas yuav ua rau koj zoo siab rau koj txoj haujlwm xwb. Cia peb ua kom yooj yim dua:

Xaiv ib sab yog tias koj xav tau lub zog siab tshaj plaws ntawm ib sab thiab xav kom tsis txhob muaj kev sib txhuam ntawm sab. Nws yog qhov kev xaiv yooj yim rau feem ntau cov khw muag khoom lag luam.

Xaiv cov neodymium ob sab yog tias koj xav tau kev sib cuam tshuam ob sab (tuav ob feem ua ke, repulsion, lossis compact dual-action). Lawv yog qhov hloov pauv loj rau kev ntim khoom, khoom siv hluav taws xob, thiab cov khoom siv hauv tsev ntse.

Xaiv 2 hauv 1 tsuas yog tias koj tsis muaj peev xwm hloov pauv tau, thiab koj txaus siab tso qee qhov zog thiab kev ruaj khov. Lawv yog cov cuab yeej tshwj xeeb, tsis yog hloov cov hlau nplaum tshwj xeeb.

Cov Lus Qhia Kawg Rau Cov Kws Tshaj Lij (Los ntawm Cov Lus Qhia Nyuaj)

1. Sim ua ntej yuav ntau. Kuv tau pom zoo rau 5,000-unit xaj ntawm ob sab neodymium hlau nplaum yam tsis tau sim hauv tus neeg siv khoom lub tsev rau khoom ntub dej - cov txheej xeb ua rau puas tsuaj 20% ntawm cov khoom. Epoxy txheej yeej nickel plating rau qhov chaw ib puag ncig hnyav.

2. Tsis txhob ua kom zoo dhau. N52 ob sab neodymium hlau nplaum suab zoo kawg nkaus, tab sis lawv tawg yooj yim. Rau feem ntau daim ntawv thov, N42 muaj zog dua (hauv kev xyaum) thiab siv tau ntev dua.

3. Kev nyab xeeb ua ntej. Txhua lub hlau nplaum neodymium muaj zog heev—ob sab tuaj yeem ntswj cov ntiv tes lossis so daim npav ruaj ntseg ntawm ko taw. Khaws cia kom deb ntawm cov khoom siv hluav taws xob thiab siv hnab looj tes thaum tuav.

Hauv paus ntsiab lus, qhov kev xaiv zoo tshaj plaws ua raws li lub hauv paus ntsiab lus ntawm "daim ntawv ua raws li kev ua haujlwm." Cia koj daim ntawv thov tshwj xeeb txiav txim siab seb lub hlau nplaum neodymium ib sab, ob sab, lossis sib xyaw 2-hauv-1 puas zoo tshaj plaws - lub hom phiaj yog kom ua tiav qhov tshwm sim xav tau nrog kev ntseeg siab tsis muaj kev cuam tshuam.
