A: Feem ntau, yog. Lub qhov hloov feem ntau txo qhov torque ripple los ntawm 8-15% mus rau 2-5%, txhim kho rotor mechanical integrity, thiab ua kom yooj yim sib dhos. Qhov kev txwv tseem ceeb yog qhov loj me: cov hlau nplaum nplhaib yog qhov tsim nyog tshaj plaws rau cov rotor diameters hauv qab 150mm. Rau cov motors loj heev saum 200mm OD, segmented arcs tej zaum tseem yuav siv tau ntau dua. Ntawm Fullzen Technology, qhov crossover point rau kev siv nyiaj txiag feem ntau yog nyob ib puag ncig 500 daim ib hlis.

Q: Koj xav tau daim ntawv pov thawj dab tsi rau EV lub cev muaj zog hlau nplaum?

A: Cov hlau nplaum EV lub cev muaj zog xav tau IATF 16949 daim ntawv pov thawj kev tswj hwm zoo, cov ntaub ntawv PPAP, thiab kev taug qab tag nrho los ntawm cov khoom siv raw mus rau cov khoom tiav. Kev ruaj khov thermal yog qhov tseem ceeb: feem ntau EV traction motors ua haujlwm ntawm 150-180 ° C tas li, xav tau 40UH lossis 45UH qib NdFeB. Ntawm Fullzen Technology, peb khaws cov ntaub ntawv taug qab tag nrho thiab txhawb nqa PPAP Qib 3 xa rau cov neeg siv khoom tsheb.

Q: Koj ua li cas thiaj tiv thaiv tau demagnetization hauv cov ntawv thov lub cev muaj zog kub siab?

A: Peb yam tseem ceeb uas ua rau tsis muaj zog demagnetization: xaiv qib kom raug (SH qib rau 150 ° C, UH rau 180 ° C), qhov sib npaug ntawm coercivity txaus (Hcj yuav tsum tshaj qhov demagnetization teb tsawg kawg 30%), thiab tsim thermal uas ua rau qhov kub ntawm qhov chaw magnet qis dua qhov ntsuas siab tshaj plaws ntawm qib. Peb xav kom khiav qhov kev tshuaj xyuas kab demagnetization ntawm qhov kub ua haujlwm phem tshaj plaws ntawm lub cev muaj zog ua ntej ua tiav qib.

Q: Lub sijhawm ua khoom siv rau cov hlau nplaum sib nqus lub cev muaj zog yog dab tsi?

A: Cov qauv qauv hauv qhov ntau thiab tsawg sib xws thiab qib N42SH xa khoom tsis pub dhau 7-10 hnub. Cov lus qhia tshwj xeeb nrog cov khoom siv magnetizing tshiab feem ntau yuav tsum tau 15-25 hnub rau thawj cov qauv. Lub sijhawm ua khoom loj yog 15-20 hnub tom qab kev pom zoo qauv, nyob ntawm qhov ntau thiab tsawg thiab qhov nyuaj. Cov nplhaib ntau tus ncej nrog 24+ tus ncej xav tau lub sijhawm ntxiv. Ntawm Fullzen Technology, peb khaws cov khoom siv raw khoom kom txo qis lub sijhawm ua khoom sib txawv.
