Magnets SmCo e tupulaga lona lua o le lalolagi seāseā magnets tumau , o se maneta tumau tulaga maualuga faia mai Sm, Co, Fe ma isi Lolomi elemene uamea. E ese a Max vevela faigaluega o le 300 ℃, ei ai tetee ofoofogia e faasaga i corrosion ma oxidation. O lea la, e mafai ona faaaogaina i alamanuia aeronautic ma avanoa aomng isi.
Gaosia SmCo5 ma Sm2Co17 magnets i siepi eseese. O le tele o auaunaga e manaomia ai togi YXG28, YXG30, YXG32, SmCo28, SmCo30, SmCo32, ma isi
Machining ma tolerances
Tatou ausia faatafa tele ma le faapalepale e tipiina po o olo ma abrasives maoae. Samarium Cobalt (SmCo) e le mafai ona eleele i le viliina masani, liliu po milling faagasologa, ma e tatau ona machined i luma o latou magnetized. Gata, fonotaga tele po o faigata e masani ona magnetized ao lumanai ai le faapotopotoga. tolerances tagavai mo Samarium magnets Cobalt e +/-. 005 "mo fua eleele. Tatou oloa magnets SmCo i poloka, mama ma avea o se tisiketi i le tele o ituaiga ma togi, ma ua atoatoa ona tatou saunia ina ia maua ai le tele ma le faapalepale e manaomia ai.
1: 5 mea uʻamea filogia
1: 5 ofoina 16 MGOe (malosi oloa) i le 22 MGOe ma e faia aʻe e tusa ma le 50% samarium ma le 50% cobalt. Le 1: 5 faasologa ua i ai se tapulaa maualuga o le vevela faagaoioia fautuaina o le 250 ° C. SmCo 1: 5 magnets manaomia malosiaga fanua maualalo ifo nai lo 2:17 mea e magnetize. I nisi tulaga, 1:15 mea e mafai ona magnetized ma pou tele, vagana ai e faapea e maua se tasi e toetoe magnetizing.
2:17 mea uʻamea filogia
2:17 ofoina 24 MGOe e 32 MGOe ma e aofia ai le tusa ma le 25% samarium, 5% kopa, 18% uʻamea, 2% hafnium po zirconium, faatasi ai ma le vaega o totoe cobalt avea. O le 2:17 faasologa o loo i ai se vevela faagaoioia aupito maualuga o le 350 ° C. o loo maua togi faapitoa o le 2:17 e mafai ona faagaoioia e oo lava i le vevela maualuga. manaomia SmCo 2:17 matua fanua magnetizing sili, ma e le mafai ona tele magnetization pou.
Tatala ma sii Technical faamaumauga o Magnets SmCo
- Meatotino maneta Faavae
- Features
- Faagasologa o Oloa Gaosia
- Lamatiaga autu
- masani Talosaga
- SmCo Magnets VS Magnets Sintered Neodymium
Faavae o Meatotino maneta:
Tapulaa maualuga le vevela faigaluega: 250-350 ° C
Tapulaa maualuga Malosiaga Oloa: (Bhmax) (15-35 MGOe)
vevela Tapulaa maualuga Galulue: (Temp.Tw) 250-350
Induction faamalosi Force: (Hcb) 4-12 (Koe )
residual magnetism: br 0.8-1.2 (T)
coefficient vevela feliuai o magnetism residual (br) -0.04 - -0,01
Vaega:
1. Silisili Coercity
2. Mausali le vevela manaia
3. Ona o le tau maaleale o cobalt, o lona tau e taugata ma faigofie ona mātalasi
O Oloa Gaosia Faagasologa o Samarium Cobalt Tumau maneta:
efuefu faagasologa → fetaomi → Sintering → vavaeina → suega meatotino maneta → uma oloa
o loo gaosia masani Samarium mea cobalt lalo o-le magnetized tulaga, faatasi ai ma uili faʻamanifi taimane ma susu olo lelei, lea e talafeagai. Ona o maualalo o le vevela o sulu, e le tatau ona matutu atoatoa samarium cobalt. Na o se tamai aloiafi pe le eletise static i tuuina e mafai ona faigofie ona faatupuina o se afi, ma le matua vevela maualuga, lea e faigata ona pulea.
Lamatiaga Autu:
Samarium magnets cobalt e magaugau. Faamolemole agalelei puipuia o outou mata, lima ma le tino pe a feagai ma i latou.
Common applications
- motors faatinoga maualuga
- couplings maneta
- eseese o maneta
SmCo Magnets VS Magnets Sintered Neodymium
O le eseesega i le va SmCo magnets ma magnets Sintered NdFeB faapitoa e aofia ai vaega nei:
1. malosi maneta
maneta tumau Neodymium e sili atu le malosi nai lo maneta SmCo faamamaluina maneta.
(BH) Max o sintered NdFeB lava i 53MGOe, ao le (BH) Max o mea SmCo o 32MGOe.
SmCo mea e malosi i le teteeina demagnetization nai lo mea NdFeb.
2. tetee vevela Ese
NdFeB e le sili o SmCo i tetee maualuga le vevela. O le vevela o le galuega aupito maualuga o NdFeB o le 200 ℃ ma ua i luga o SmCo e 350 ℃.
3. Corrosion tetee
e le ina lelei magnets NdFeB i tetee oxidation ma corrosion. E masani lava latou e tatau ona puipuia e plating po o teuina lagona gaogao. Ituaiga taatele o -O aofia metala paʻepaʻe, limasene, epoxy ma isi. SmCo magnets le a le rusting aunoa plating.
4. foliga, gaosiga ma faapotopoto
NdFeb ma SmCo ua uma mea maʻaleʻale, ina ia mafai ai ona gaosia i latou e gaosi vavaeina masani.
O le auala lautele gaosi o vavaeina uaea-electrode ma taimane vavaeina uili. O le foliga producible o nei magnets ua faatapulaaina. Ua foliga faigata e le aogā. Matua tautala, SmCo mea e sili atu ona maaleale ma sili atu ona faigofie ona solia. O le mea lea, faamolemole ia faaeteete lava ia i le faatulagaina ma le faaaogaina o magnets SmCo.
5. Tau
I ni nai tausaga ua mavae, o le tau o magnets SmCo sa faalua po o le sili atu nai lo o magnets NdFeB.
I tausaga talu ai nei, o le tau o NdFeB ua toetu tele ona o le faiga tapulaa a le Atunuu i le laʻuina o le masani-lalolagi. Lona uiga moni lava, magnets masani NdFeB e taugofie nai lo samarium cobalt.
