Mwambo Neodymium mphete Magnet kwa Motor ndi Wokamba
Mafotokozedwe Akatundu
Neodymium ndi chitsulo chosungunula komanso chosalala chasiliva-choyera.Neodymium ndi paramagnetic kwambiri.Kugwiritsa ntchito kwakukulu kwa neodymium kuli mu maginito okhazikika amphamvu kwambiri ozikidwa pa Nd2Fe14B omwe amagwiritsidwa ntchito pama injini amagetsi ochita bwino kwambiri ndi ma jenereta, komanso maginito opindika a ma hard drive apakompyuta ndi ma turbine amphepo.Maginito a Neodymium amapezeka mumitundu yosiyanasiyana, makulidwe ndi magiredi.Maginito a mphete ali ngati ma disc kapena masilinda, koma okhala ndi dzenje lapakati.
Pete NdFeB Maginito Makhalidwe
1. Kutentha kwakukulu kwa ntchito
Maginito a mphete a N48H neodymium ali ndi kukana kwambiri kutentha.Pakuti NH mndandanda NdFeB maginito, pazipita ntchito kutentha akhoza kufika 120 ℃.

3. Kuphimba / Kuyika
Zosankha: Ni-Cu-Ni, Zinc (Zn), Black Epoxy, Rubber, Gold, Silver, etc.
4. Maginito Direction
Maginito a mphete amatanthauzidwa ndi miyeso itatu: Kunja kwa Diameter (OD), M'kati mwa Diameter (ID), ndi Kutalika (H).
Mitundu ya maginito ya maginito a maginito a maginito ndi axially magnetized, diametrically magnetized, radially magnetized, and multi-axially magnetized.
