Kufananiza Magwiridwe Pakati pa Neodymium Channel Magnets ndi Mitundu Ina Yamaginito

"Superhero" ya Magnets: Chifukwa chiyani Arc NdFeBMaginito a ChannelWamphamvu Chonchi?

Hei nonse! Lero, tiyeni tiyankhule za maginito - izi zomwe zikuwoneka ngati wamba koma zochititsa chidwi. Kodi mumadziwa? Kusiyana kwa maginito osiyanasiyana ndikofanana ndi komwe kuli pakati pa mafoni ndi mafoni oyambira! Makamaka maginito a NdFeB (Neodymium Iron Boron) omwe akhala akuyenda posachedwa - kwenikweni ndi "Iron Man" ya dziko la maginito. Ndiye ndi zodabwitsa bwanji kwenikweni? Nchiyani chimawapangitsa iwo kukhala osiyana ndi maginito ena? Osadandaula, tiphwanya pang'onopang'ono.

 

1. Kumanani ndi Banja la Magnet

Choyamba, tiyeni tidziwitse "mabanja anayi akuluakulu" a maginito:

Maginito a NdFeB - "opambana kwambiri" a maginito

Pakadali pano maginito amphamvu kwambiri padziko lonse lapansi

Wopangidwa ndi neodymium, chitsulo, ndi boron

Monga "omanga thupi" a maginito - amphamvu kwambiri koma osamva kutentha pang'ono

Maginito a Ferrite - The "workhorses"

 

Njira yachuma kwambiri

Amapangidwa kuchokera ku iron oxide ndi strontium/barium mankhwala

Kukana kwabwino kwa dzimbiri koma mphamvu yocheperako ya maginito

AlNiCo Magnets - "akatswiri akale okhwima"

Chimodzi mwazinthu zakale kwambiri zamaginito zokhazikika

Kukhazikika kwapadera kwa kutentha

Monga othamanga obiriwira omwe ali ndi mphamvu zotsutsana ndi demagnetization

Maginito a SmCo - "olemekezeka apamwamba"

 

Wina mkulu-ntchito osowa padziko maginito

Zosatentha komanso zosachita dzimbiri

Yamtengo wapatali kuposa NdFeB, yopangira mapulogalamu apamwamba

 

2. The Superpowers wa NdFeB Channel maginito

 

Chifukwa chiyani amawatcha "Iron Man"? Chifukwa iwo ali ndi luso lodabwitsa:

 

Mphamvu Zamaginito Zosafanana

10 wamphamvu kwambiri kuposa maginito a ferrite! (Tangoganizani wonyamulira zitsulo motsutsana ndi wophunzira wapulaimale)

Remanence imafika pa 1.0-1.4 Tesla (maginito okhazikika amangopeza 0.2-0.4)

Kuthekera kwapamwamba kotsutsa demagnetization, ngati mphemvu yosawonongeka

 

Mapangidwe Anzeru a Channel

Mapangidwe a Groove amalola kuwongolera koyenera kwa maginito, monga kupereka maginito GPS navigation

Okhazikika bwino, ocheperako "fractures"

Zosavuta kukhazikitsa, monga kusonkhanitsa midadada ya Lego

 

King of Cost Performance

Ngakhale mtengo wagawo ndi wapamwamba kuposa ferrite, umapereka mtengo wotsika kwambiri pagawo lililonse la maginito

Imakwaniritsa maginito amphamvu ndi kukula kochepa, ndikupulumutsa malo ndi ndalama

 

3. Nthawi Yosankha "Superhero" iti?

 

Sankhani NdFeB Channel maginito pamene:

Malo ndi ochepa koma maginito amphamvu amafunikira (monga makutu opanda zingwe, ma motor vibration motors)

Kuwongolera koyenera kwa maginito kumafunika (mwachitsanzo, zida zamagetsi zamagetsi, masensa)

Kuyenda pafupipafupi komwe kumakhudzidwa (mwachitsanzo, ma EV motors, ma drone motors)

Kupanga kopepuka ndikofunikira kwambiri (zida zam'mlengalenga)

 

Sankhani maginito ena pamene:

Kutentha kwambiri (kupitirira 200 ° C)

Kuwononga kwambiri (zida zam'mphepete mwa nyanja)

Bajeti yolimba yopangira zinthu zambiri

Zida zomwe zimakhudzidwa kwambiri ndi kusintha kwa kutentha

 

4. Malangizo Ogwiritsa Ntchito Maginito a NdFeB

 

Apatseni "zovala":Kuphimba pamwamba (nickel, zinki, kapena epoxy) pofuna kupewa dzimbiri

Iwo ndi "galasi-mtima":Gwirani mosamala pakuyika - ndizovuta

Zosamva kutentha:Kutentha kwambiri kungayambitse "kutayika kwa minofu" kosatha (demagnetization)

Direction ndi yofunika: Ayenera kukhala ndi maginito molingana ndi kapangidwe kake

Gwirani ntchito mosamala:Maginito amphamvu amatha kukhudza makhadi a ngongole, mawotchi; khalani kutali ndi ogwiritsa ntchito pacemaker

 

5. Kodi Tsogolo Lili Lotani?

 

Matembenuzidwe amphamvu:Asayansi akupanga magiredi atsopano amphamvu kwambiri

Zosatentha kwambiri:Kuwapangitsa kuti asamavutike kwambiri ndi kutentha kwambiri

Mapangidwe anzeru:Kugwiritsa ntchito makompyuta kukhathamiritsa machanelo

Njira zobiriwira: Kupititsa patsogolo ukadaulo wobwezeretsanso, kuchepetsa kugwiritsidwa ntchito kosowa kwapadziko lapansi

Zokwera mtengo: Kuchulukitsa zopanga kuti zichepetse ndalama

 

Malingaliro Omaliza

Maginito a NdFeB ali ngati "akatswiri ozungulira" a dziko la maginito, chisankho choyamba pamapulogalamu apamwamba kwambiri. Koma siamphamvuzonse - monganso simungagwiritse ntchito galimoto yamasewera kunyamula katundu, chinsinsi ndikusankha chida choyenera pantchitoyo.
