Segment Ferrite Magnets
Segment Ferrite Magnets, tseem hu ua ceramic ntu / arc hlau nplaum, yog siv dav hauv motors thiab rotors.
Ferrite Magnets muaj qhov dav tshaj plaws sib nqus ntawm tag nrho cov hlau nplaum thiab zoo tiv thaiv corrosion. Txawm hais tias nws yog cov hlau nplaum uas tsis muaj zog, Ferrites tau siv ntau yam kev siv xws li motors, dej txias, hais lus, reed keyboards, crafts thiab magnetic kho.
Vim yog txoj kev siv los tsim lawv, cov hlau nplaum nyuaj ferrite qee zaum hu ua cov hlau nplaum ceramic. Hlau oxide nrog strontium lossis barium ferrites yog siv feem ntau hauv cov hlau nplaum ferrite. Ob leeg isotropic thiab anisotropic ntau yam ntawm hard ferrite (ceramic) hlau nplaum yog tsim. Cov hlau nplaum ntawm hom isotropic tej zaum yuav magnetized nyob rau hauv ib qho kev taw qhia thiab yog manufactured yam tsis muaj orientation. Thaum tsim, anisotropic hlau nplaum yog raug rau ib qho chaw electromagnetic thiaj li yuav ua rau kom lawv lub zog sib nqus thiab cov yam ntxwv. Qhov no yog ua tiav los ntawm squeezing qhuav hais los yog slurry, nrog los yog tsis muaj orientation, mus rau hauv ib tug xav tuag kab noj hniav. Sintering yog txheej txheem ntawm kev xa cov khoom mus rau qhov kub thiab txias tom qab compaction rau hauv cov tuag.
Nta:
1. Muaj zog coercivity (= siab tsis kam rau demagnetization ntawm cov hlau nplaum).
2. Muaj kev ruaj khov nyob rau hauv ib puag ncig hnyav, tsis tas yuav tsum muaj kev tiv thaiv npog.
3. High oxidation tsis kam.
4. Lub neej ntev - cov hlau nplaum ruaj khov thiab zoo ib yam.
Ferrite hlau nplaum yog dav siv nyob rau hauv automotive sector, hluav taws xob motors (DC, brushless, thiab lwm yam), sib nqus sib nqus (feem ntau daim hlau), cov khoom siv hauv tsev, thiab lwm yam kev siv. Permanent Tsav Rotor Magnets nrog Segment Ferrite.
