NdFeB permanent magnet material overview
1. NdFeB magneter introduction
NdFeB magneter, også kendt som NdFeB-magneter, er tetragonale krystaller dannet af neodym, jern, og bor (Nd2Fe14B). NdFeB er den tredje generation af sjældne jordarters permanentmagnet, som hedder “Magnetisk konge” på grund af dens fremragende ydeevne.
High-performance NdFeB refers to sintered NdFeB permanent magnet materials whose sum of intrinsic coercivity (HcikOe) and maximum magnetic energy product ((BH)maxMGOe) is greater than 60.
2. NdFeB permanent magnet material klassifikation
NdFeB permanent magnet material is the representative of rare earth permanent magnet material. I henhold til forskellige produktionsprocesser, it can be divided into three types: sintring, limning og varmpresning.
Sintered NdFeB is currently the most widely used rare earth permanent magnet material.
3. NdFeB permanent magnet material application field
Compared with traditional permanent magnet materials, NdFeB has excellent permanent magnet properties and high cost performance.
På nuværende tidspunkt, sintered NdFeB is widely used in automobiles (electric drives, electric power steering and sensors, etc.), wind power generation, information industry (hard disk drives, CD drives), consumer electronics (Først, digitale kameraer), household appliances (inverter klimaanlæg, refrigerators and washing machines), elevator linear motors, nuclear magnetic resonance imagers and other fields.
