Muri Fullzen Technology, aho crossover ikoresha kugira ngo ihendutse ni ibice bigera kuri 500 ku kwezi.

Q: Ni izihe certification ukeneye kuri magnets za moteri za EV?

A: Magneti za moteri za EV zisaba icyemezo cy’ubwiza bwa IATF 16949, inyandiko za PPAP, no gukurikirana neza kuva ku bikoresho fatizo kugeza ku bicuruzwa byarangiye. Guhagarara neza mu bushyuhe ni ingenzi cyane: moteri nyinshi zitwara amashanyarazi zikora kuri dogere selisiyusi 150-180 buri gihe, bigasaba 40UH cyangwa 45UH NdFeB. Muri Fullzen Technology, dukomeza kubika amakuru yose yerekeye gukurikirana neza kandi dushyigikira kohereza PPAP ku rwego rwa 3 ku bakiriya b’imodoka.

Q: Ni gute wakwirinda ko moteri zikoresha moteri zikoresha ubushyuhe bwinshi zikoresha moteri zikoresha amashanyarazi?

A: Ibintu bitatu bibuza gukuraho ingufu za magnetiki: guhitamo neza amanota (igipimo cya SH kuri 150°C, UH kuri 180°C), ingano ihagije y’imbaraga za magnetiki (Hcj igomba kurenga nibura 30%), hamwe n’imiterere y’ubushyuhe butuma ubushyuhe bw’ubuso bwa magnetiki buguma munsi y’igipimo ntarengwa cy’igipimo. Turakugira inama yo gukora isesengura ry’inyuguti za magnetiki ku bushyuhe bukabije bw’imikorere ya moteri mbere yo kurangiza amanota.

Q: Ni ryari igihe gisanzwe cyo gukoresha magneti za moteri zikozwe mu buryo bwihariye?

A: Ingero zisanzwe mu bunini busanzwe no koherezwa mu rwego rwa N42SH mu minsi 7-10. Ibipimo byihariye hamwe n'ibikoresho bishya bya magnetizing bikunze gusaba iminsi 15-25 ku ngero za mbere. Igihe cyo gutanga umusaruro ni iminsi 15-20 nyuma yo kwemezwa kw'icyitegererezo, bitewe n'ingano y'ibicuruzwa n'uburemere. Impeta nyinshi zifite inkingi zigera kuri 24 zisaba igihe cy'inyongera cyo gushyiraho. Muri Fullzen Technology, dukomeza kubika ibikoresho bisanzwe kugira ngo tugabanye ihindagurika ry'igihe cyo gushyiraho.
