  • Maginito a SmCo

    Kufotokozera Kwachidule:

    Maginito a SmCo amaimira mibadwo yatsopano yamagetsi yamagetsi. Zimapangidwa zaka zoposa 40 zapitazo ndipo zidabweretsa nthawi yamagalimoto okhazikika maginito. Panthawiyo, zinthu zosowa zapadziko lapansi zinali zodula kwambiri. M'zaka za m'ma 1980, zinthu za SmCo zinali m'malo mwa maginito a NdFeB. Chifukwa cha kukwera kwamitengo yayikulu mu neodymium ndi dysprosium (Nd / Dy) wosowa kwambiri, nkhaniyi tsopano yatchuka chifukwa chogwiritsa ntchito kutentha kwambiri (150 ° C - 200 ° C). Komabe, pali malire omwe akhazikitsidwa pazinthu zakuthupi pazakufikirika kwakanthawi. Mitundu iwiri ikuluikulu ya maginito SmCo zilipo, 1: 5 mtundu (SmCo5) ndi 2:17 mtundu (Sm2Co17). Maginito SmCo ndi katundu wapamwamba mkulu maginito ndi katundu kutentha.

     Zindikirani:
    · Tikhalabe ofanana ndi pamwambapa pokhapokha titanenedwa kuchokera kwa kasitomala. Kutentha kwa curie ndi koyefishienti yakutengera ndi yongotchula kokha, osati ngati maziko osankhira.

     

    Mwayi:
    Kugwiritsa ntchito maginito awa kutenthedwa ndi kutentha kosiyanasiyana kothamanga kuchokera ku 250ºC mpaka 350ºC ndipo kutentha kwawo kwa Curie kumatha kukhala kwakukulu

    monga 710 mpaka 880 ° C. Choncho, maginito a SmCo ali ndi maginito abwino kwambiri chifukwa chokana kutentha kwambiri.

    SmCo maginito amakhala ndi kukana kwambiri dzimbiri, palibe coating kuyanika chofunika chitetezo pamwamba.

     

    Mbali:
    Chosavuta cha maginito a SmCo ndikumveka kofewa kwa zinthuzo - chinthu chomwe chiyenera kukumbukiridwa makamaka pokonza.

    Ma maginito amawerengedwa kapena wokutidwa ndi cathodic electrodeposition pazinthu zina.

     

    Ntchito:
    M'madera otentha kwambiri, kutentha kwakukulu ndi kukaniza makutidwe ndi okosijeni ndizofunikira. Monga, Magnetron yamagetsi,Maginitokufalitsa kwa ic,

    Chithandizo cha maginito, Magnistor, ndi zina zambiri.

    Malingaliro onse adatsimikizika pogwiritsa ntchito zitsanzo zofananira malinga ndi IEC 60404-5. Zotsatirazi zikugwiritsidwa ntchito ngati zowunikira ndipo mwina

    kusiyana. Zolemba. kutentha opaleshoni kumadalira dimesion maginito ndi ntchito yeniyeni. Kuti mudziwe zambiri lemberani athu

    akatswiri opanga mapulogalamu.
