Compact Annular Fais Fab rau Rotary Applications
Rau cov kws tsim qauv tsim cov khoom siv sib hloov uas yuav tsum muaj ob qho tib si hauv nruab nrab thiab siab sib nqus flux, lubmuaj zog neodymium hlau nplaum nplhaibmuab kev daws teeb meem zoo. Cov annular sintered NdFeB hlau nplaum tsim tuav lub zog los yog tsav torques piv rau cov khoom discs tab sis cia bolts, rods, los yog shafts mus rau hauv nruab nrab. Cov ntawv thov muaj xws li sib nqus couplings (torque kis tau tus mob los ntawm qhov thaiv qhov thaiv), brushless DC lub cev muaj zog rotors, teb encoders, thiab cov hlau nplaum ruaj khov grippers. Pebmuaj zog neodymium hlau nplaum ringsyog tsim los ntawm 100% nkauj xwb tsis tshua muaj-lub ntiaj teb cov ntaub ntawv (purity Ntau tshaj los yog sib npaug rau 95%) nrog tag nrho ntsug kev koom ua ke - los ntawm alloy melting mus rau qhov kawg magnetization. Qib ntau ntawm N35 (kev lag luam) txog N52 (lub zog siab tshaj plaws), nrog rau qhov kub siab N42SH, N40UH, thiab N38EH kev xaiv rau ib puag ncig txog 200 degree. Precision ID / OD sib tsoo ua tiav concentricity nyob rau hauv ± 0.03 hli thiab phab ntsa thickness uniformity ntawm ± 0.02 hli, tseem ceeb rau high-ceev kev sib hloov thiab zoo ib yam ntawm cov huab cua sib txawv. Standard Ni‑Cu‑Ni triple plating (13-18 μm) muab ntau dua lossis sib npaug rau 72 teev ntsev tsuag tshuaj tiv thaiv; epoxy lossis kub txheej yog muaj rau cov kev xav tau tshwj xeeb. Kev cai ntau thiab tsawg (OD los ntawm 5 hli mus rau 150 hli, ID los ntawm 2 hli mus rau 120 hli), multi-pole magnetization qauv (2 mus rau 48 ncej), thiab axial los yog diametrical orientation yog muaj rau OEM tej yaam num.
Vim li cas lub Nplhaib Geometry muab kev sib xyaw ua ke zoo tshaj plaws
Los ntawm-ncej Mounting
A muaj zog neodymium hlau nplaum nplhaibslides ncaj qha mus rau ib tug ncej los yog ntsia liaj qhov rooj. Qhov no tshem tawm cov nplaum nplaum sib txuas lossis cov vaj tsev sab nraud, ua kom yooj yim sib dhos thiab txo cov rotor inertia tag nrho.
Multi-Pole Magnetization
Peb magnetize rings nrog leej axial (los ntawm thickness) los yog diametrical qauv. Kev teeb tsa ntau tus ncej (txog 48 tus ncej) muaj rau kev tawm tswv yim encoder thiab kev ntsuas siab ceev.
Siab Torque Density
Concentrating cov khoom sib nqus nyob ze ntawm txoj kab uas hla sab nraud uas lub zog tangential siab tshaj tso cai rau amuaj zog neodymium hlau nplaum nplhaibkom ua tau zoo heev torque ib chav tsev qhov hnyav, zoo tagnrho rau compact couplings thiab motors.

FAQ
Q: Dab tsi txhais tau tias "muaj zog" neodymium hlau nplaum nplhaib piv rau cov nplhaib txheem?
A: A strong ring typically uses grade N48–N52, with Br >1.42 T. Phab ntsa tuab yog txo kom haum rau hauv cov rooj sib txoos ua ke thaum tswj cov dej ntws siab. Lub zog kuj yog nyob ntawm cov kev taw qhia magnetization: axial rings xa ntau zog rub rau lub ntsej muag-to-fab attraction tshaj radially magnetized rings ntawm tib qhov loj.
Q: Yuav ua li cas yog ob qho tib si magnetization cov lus qhia rau ib tug neodymium nplhaib hlau nplaum?
A: Axial magnetization (sab qaum teb ntawm ib lub ntsej muag tiaj tus, sab qab teb ntawm lwm qhov) yog tus qauv rau kev tuav thiab sib txuas. Radial magnetization (sab qaum teb ntawm OD, sab qab teb ntawm ID) yog siv rau hauv motors, sensors, thiab magnetic bearings. Radial rings yuav tsum tau tshwj xeeb fixtures thiab raug nqi 30-50% ntau tshaj axial.
Q: Koj yuav ua li cas tiv thaiv kev tawg thaum sib sau ua ke lub nplhaib neodymium rau ntawm cov ncej hlau?
A: Lub zog muaj zog tuaj yeem slam lub nplhaib rau hauv cov ncej, ua rau tawg tawg. Siv cov lus qhia uas tsis yog hlau nplaum (xws li, tooj dag lossis yas), nias maj mam nrog lub xovxwm arbor, lossis thermally shrink lub nplhaib (kub mus rau 150 degree) kom nthuav ID ua ntej zawv zawg mus rau ntawm ncej.
Q: Vim li cas neodymium nplhaib hlau nplaum muaj zog rub qis dua li lub disc ntawm tib OD thiab tuab?
A: Lub nplhaib muaj qhov chaw hollow, txo qhov chaw sib nqus zoo. Rau axial magnetization, rub quab yuam scale roughly nrog thaj tsam annulus (π(OD²-ID²)/4). Ib lub disc ntawm tib OD tuaj yeem muaj 30-60% siab dua rub quab yuam, tab sis lub nplhaib tso cai rau lub taub hau lossis cable hla dhau.
Q: Lub nplhaib neodymium muaj zog tuaj yeem siv los ua cov khoom sib nqus sib nqus?
A: Yog lawm, lub nplhaib sib nqus hlau nplaum ntau lub nplhaib (alternating N / S ncej nyob ib ncig ntawm lub voj voog) yog ib qho kev sib hloov encoders. Nws yuav tsum muaj lub suab meej meej (piv txwv li, 2 hli ib tus ncej-pair) thiab qis qis. Qib N42SH lossis N38EH zoo dua rau kev ua haujlwm ruaj khov ntawm -40℃txog +150℃.
