Sintered NdFeB leman yo se leman pèmanan komèsyalize ki pi pwisan ki disponib jodi a, ak pwodwi enèji maksimòm ki sòti nan 26 MGOe a 52 MGOe. Nd-Fe-B se twazyèm jenerasyon leman pèmanan devlope nan ane 1980 yo. Li gen yon konbinezon de remanans trè wo ak coercivity, epi li vini ak yon pakèt klas, gwosè ak fòm. Avèk ekselan karakteristik mayetik li yo, abondan materyèl bwit ak pri relativman ba, Nd-Fe-B ofri plis fleksibilite nan konsepsyon nouvo oswa ranplase materyèl leman tradisyonèl yo tankou seramik, Alnico ak Sm-Co pou reyalize efikasite segondè, pri ki ba ak plis ankò. aparèy kontra enfòmèl ant.
Avantaj nan leman sintered
* Ekstrèm fò endiksyon Br Rezidan.
* Ekselan kapasite rezistans demagnetization.
*Bon pri parapò ak pwopriyete segondè mayetik li yo.
