| Noat: · Under wurkjende temperatuer 20 ℃ ± 2 ℃, boppe magnetyske parameters en fysike eigenskippen wurde hifke, mei ûnûntkomber ferlies fan magnetyske krêft net mear as 5%. · De maksimale wurkjende temperatuer fan magneet is feroare fanwege ferhâlding fan lingte en diameter en miljeu faktoaren . | ||||||||
Foardiel:
De eigenskippen fan dizze magneten binne fier superieur oan tradisjonele en se binne op it stuit de machtichste yn tapassing. Harren hege
twang en hege remaninsje tastean it nije ûntwerp en de mooglikheid fan tanimmend magnetysk fjild fan tapassing dêr't romte is beheind
of wêr't in sterk magnetysk fjild nedich is.
NdFeB magneten binne tige gefoelich foar corrosie. Dêrom fereaskje in beskermjende oerflak coating. Gebrûk fan NdFeB-magneet wurdt betingst
troch de temperatuer yn in breed berik rint fan 80ºC oant 230ºC. En ek it wurket by temperatueren ûnder 0 ℃.
Oanfraach:
Neodymiummagneten wurde brûkt as ferskate soarten magnetyske linzen foar fokus, ôfwiking fan opladen dieltsjes yn elektroanika, remsystemen,
drip, sensor, magnetysk systeem yn rotor- en mikromotoren, en fjild fan wittenskip, medisinen (tomografy, NMR-spektrometers), ensfh.
Hjoed, NdFeB magneten wurde brûkt yn grutte hoemannichten oer de hiele wrâld. De ûntwikkeling fan dit materiaal is noch net folslein; de remaninsje
en twangfjildsterkte wurde kontinu ferhege. De hege enerzjy fan NdFeB magneten betsjut dat motors en sensors kinne wurde boud
hieltyd lytser - en dit betsjut in ferheging fan prestaasjes effisjinsje. De oanhâldende ferbetteringen meitsje it mooglik om dit nijsgjirrige materiaal te kontinu-
jierliks ynfierd yn nije gebieten.
Alle oanjûne wearden waarden bepaald mei standertmonsters neffens IEC 60404-5. De folgjende spesifikaasjes tsjinje as referinsje wearden en
kin ferskille. Foar mear ynformaasje nim dan kontakt op mei ús applikaasje-yngenieurs.
