Aplikasi: Digunakake ing motor tanpa sikat, motor industri magnet permanen, motor tekstil, motor mobil, motor penggerak langsung magnet permanen, motor linear, motor kompresor AC, peralatan mekanik motor magnet permanen, generator laut, generator magnet permanen, motor propulsi magnet permanen , Pertambangan motor magnet permanen, motor kopling, motor magnet permanen kimia, motor penggerak kanggo EV, motor pompa, motor EPS, sensor lan area liyane.
Product selaras: magnet kabeh selaras, dawa bisa saka 0.5mm-200mm, jembaré saka 0.5mm-150mm, kekandelan saka 0.5mm-70mm, kang bisa ketemu paling requirement pelanggan.
Coating: NdfeB magnet gampang dioksidasi, mula biasane butuh lapisan, lapisan sing umum digunakake ing pasar kaya:
1. ZN plating (sejenis lapisan logam, test semprotan uyah bisa tekan 24-48 jam, kinerja biaya dhuwur, supaya iku salah siji saka pilihan sing paling apik kanggo paling pelanggan).
2. NICUNI (sejenis lapisan logam, tes semprotan uyah bisa nganti 48-72 jam, kinerja biaya luwih dhuwur tinimbang ZN, nanging isih akeh digunakake ing pasar kondisi perakitan atos, syarat resistance karat produk saka customer bisa milih).
3. Epoxy (lapisan non-logam, konduktivitas non-magnetik, bisa nyuda mundhut saiki eddy motor, test semprotan uyah bisa tekan 72-96 jam, biaya luwih saka ZN lan lapisan NICUNI.)
4. Lapisan liyane sing uga digunakake: Fosfat, Sn, Au, Ag, Parylene lan liya-liyane ...
Toleransi: Biasane toleransi magnet kita +/- 0.05mm sawise lapisan.
