Txhua lub hlau nplaum Fullzen yuav tsum dhau Helmholtz coil kuaj ua ntej xa khoom - qhov no yog thawj kauj ruam hauv peb cov txheej txheem QC tus qauv.

Kev Ntsuas Ntsuas Hall (Kev Faib Tawm Hauv Tebchaws)

Kev ntsuas ntsuas ntawm Hall probe ntsuas qhov kev faib tawm ntawm lub zog sib nqus thoob plaws qhov chaw ntawm lub zog sib nqus - qhov tseem ceeb tshaj plaws rau cov nplhaib ntau tus ncej.

Lub Ntsiab Cai:Ib lub Hall probe tig thiab luam theej raws qhov chaw ntawm lub hlau nplaum, sau cov zog ntawm txhua qhov chaw kaum sab xis.

Lub Hom Phiaj:Txheeb xyuas qhov sib npaug ntawm cov ncej (inter-pole symmetry), cov duab ntawm lub zog (sinusoidal/square-wave purity), thiab qhov sib xws ntawm cov ncej (pole-pitch) hauv cov nplhaib ntau lub ncej (multi-pole rings).

Cov ntsuas tseem ceeb:Qhov sib txawv ntawm thaj chaw ntawm cov ncej sib ze yuav tsum tsis pub tshaj ± 3%; cov nplhaib encoder xav tau ± 1%.

Cov neeg siv khoom encoder feem ntau xav tau cov ntawv qhia txog Hall probe scan. Ntawm Fullzen, qhov no yog ib yam khoom QC txheem rau cov encoder rings.

Txoj Kev Siv Hmoov Hlau (Tshawb Xyuas Sai)

Txoj kev siv hmoov hlau yog txoj kev tshuaj xyuas zoo tshaj plaws - hmoov hlau uas tau muab nchuav rau ntawm qhov chaw ntawm lub hlau nplaum sib dhos raws cov kab ntws, qhia ncaj qha rau qhov kev faib tawm ntawm thaj chaw.

Lub Hom Phiaj:Kev txheeb xyuas sai sai tias qhov kev taw qhia magnetization yog qhov tseeb, tus lej ncej yog qhov tseeb, thiab tsis muaj qhov tsis zoo ntawm magnetization pom tseeb.

Kev txwv:Tsuas yog qhov zoo xwb; tsis muab cov nqi lej. Qhov tseeb yog qis dua li ntawm Hall probe scanning.

Txoj kev siv hmoov hlau feem ntau yog siv rau kev tshuaj xyuas thawj zaug thiab kev cais cov khoom sai sai ntawm cov kab ntau lawm - tsis haum rau QC tawm mus, tab sis zoo heev rau kev tshuaj xyuas tuaj thiab kev lees paub sai tom qab magnetization.

Cov Lus Nug Feem Ntau

Q: Puas tuaj yeem rov ua dua lub nplhaib hlau nplaum rau hauv qhov kev taw qhia sib txawv tom qab pib magnetization?

A: Tsis yog. Rau cov hlau nplaum NdFeB ring sintered, qhov kev taw qhia magnetic raug txiav txim siab thaum lub sijhawm nias. Thaum magnetized, rov magnetizing hauv lwm qhov kev taw qhia yuav tsis ua haujlwm vim tias cov magnetic domains twb tau sib phim lawm. Yog tias koj xav tau hloov qhov kev taw qhia magnetization, koj yuav tsum xaj cov hlau nplaum tshiab nrog qhov kev taw qhia raug teev tseg ua ntej nias. Ntawm Fullzen Technology, peb paub meej qhov kev taw qhia magnetization hauv theem kos duab kom tsis txhob muaj teeb meem no.

Q: Lub hlau nplaum 30 hli OD nplhaib tuaj yeem txhawb nqa pes tsawg tus ncej?

A: Lub hlau nplaum 30 hli OD feem ntau tuaj yeem txhawb nqa txog li 16–20 tus ncej, nyob ntawm seb phab ntsa tuab npaum li cas thiab qhov dav tsawg kawg nkaus ntawm tus ncej. Nrog rau qhov tsawg kawg nkaus ntawm tus ncej arc ntawm 3 hli, qhov ncig sab nraud tso cai kwv yees li 31 tus ncej siab tshaj plaws, tab sis cov kev txwv ua tau zoo - kev sib nqus ntawm cov khoom siv, qhov tuab ntawm phab ntsa, thiab kev xau dej ntawm tus ncej - txwv feem ntau cov qauv tsim rau 16–20 tus ncej. Peb xav kom paub meej koj cov lej ncej nrog peb pab neeg ua haujlwm engineering ua ntej xaj cov khoom siv.

Q: Vim li cas radial magnetization kim dua li axial?

A: Kev sib nqus radial xav tau ib lub khoom siv tshwj xeeb uas tsim kom muaj lub zog radial los ntawm ID mus rau OD, uas nyuaj rau tsim thiab tsim dua li lub phaj axial yooj yim. Cov khoom siv radial feem ntau raug nqi 5–20 npaug ntau dua li cov khoom siv axial ($ 600–$ 6,000+ nyob ntawm qhov loj ntawm lub nplhaib thiab suav tus ncej). Tsis tas li ntawd, kev sib nqus radial muaj qhov tso zis qis dua (feem ntau 90–95% vs 98%+ rau axial) vim yog qhov xav tau lub zog teb siab dua thiab kev sib dhos precision xav tau.

Q: Tus qauv magnetization twg zoo tshaj plaws rau BLDC motors?

A: Rau feem ntau ntawm BLDC lub cev muaj zog, ntau-pole radial magnetization yog qhov kev xaiv txheem. Inrunner BLDC lub cev muaj zog feem ntau siv 8-14 ncej; outrunner lub cev muaj zog siv 12-24 ncej. Qhov kev taw qhia radial teb (ID-rau-OD) sib phim nrog txoj kev sib txawv ntawm huab cua, muab 15-20% kev siv ntau dua li axial magnetization. Ntawm Fullzen Technology, ntau dua 70% ntawm peb cov neeg siv khoom lub cev muaj zog xaj qhia ntau-pole radial magnetization.

Q: Qhov kub siab tshaj plaws rau cov hlau nplaum ntau lub nplhaib yog dab tsi?

A: Cov hlau nplaum ntau tus ncej ua raws li qhov kub thiab txias ib yam li cov hlau nplaum txheem - N35–N45 qib ua haujlwm txog li 80 ° C, thaum SH qib kov 150 ° C thiab UH qib kov 180 ° C. Txawm li cas los xij, cov nplhaib ntau tus ncej ntsib kev pheej hmoo demagnetization siab dua ntawm qhov kub siab vim tias cov seem ncej nyias muaj qhov tsis kam demagnetization qis dua. Rau cov ntawv thov lub cev muaj zog saum toj no 120 ° C, peb pom zoo kom siv 38SH lossis 40UH qib es tsis yog tus qauv N42.
