Muaj peb pawg tseem ceeb ntawm cov vuas sib nqus raws li lawv cov ntaub ntawv raw:
①Ferrite sib nqus pobzeb ②NdFeB sib nqus pobzeb ③AlNiCo sib nqus pobzeb
1. Lub hom phiaj ntawm cov nplais sib nqus:
Cov vuas hlau nplaum feem ntau yog siv rau hauv cov hlau nplaum ruaj khov DC motors, uas txawv ntawm cov tshuab hluav taws xob electromagnetic uas tsim cov peev txheej sib nqus los ntawm cov coils excitation. Cov hlau nplaum tas mus li siv cov khoom siv hlau nplaum tas li los tsim cov khoom siv hlau nplaum tas li. Cov pobzeb hlau nplaum ruaj khov muaj ntau yam zoo es tsis txhob siv hluav taws xob, uas tuaj yeem ua rau lub cev muaj zog yooj yim hauv cov qauv, yooj yim hauv kev saib xyuas, lub teeb hauv qhov hnyav, me me, txhim khu kev qha hauv kev siv, siv tooj liab tsawg, tsis siv tooj liab, thiab kev siv hluav taws xob tsawg. .
Kev cuam tshuam ntawm kev ua haujlwm ntawm cov nplais sib nqus ntawm lub cev muaj zog:
(1) High residual magnetic induction intensity Br tuaj yeem xyuas kom meej tias lub cev muaj zog muaj kev kub ceev, cov zis loj torque, thiab lub zog loj. Lub cev muaj zog yuav muaj kev ua haujlwm siab dua.
(2) High Hcb tuaj yeem ua kom lub zog hluav taws xob xav tau los ntawm lub cev muaj zog, ua kom lub cev muaj zog ua haujlwm ze rau qhov khoom siv hluav taws xob ntau tshaj plaws, thiab ua kom muaj peev xwm ntawm cov hlau nplaum.
(3) High Hcj tuaj yeem ua kom ntseeg tau tias lub cev muaj zog tiv thaiv overload demagnetization thiab tiv thaiv kev laus, tiv thaiv qhov kub tsis tshua muaj peev xwm.
(4) Siab (BH) max. Qhov siab dua qhov (BH) max, qhov zoo dua qhov ua haujlwm coefficient ntawm cov hlau nplaum ruaj khov ferrite hauv lub cev muaj zog.
(5) Qhov loj dua lub zog sib nqus, qhov zoo dua, uas yuav ua rau kev ua haujlwm zoo ntawm lub cev muaj zog.
(6) Qhov zoo dua qhov squareness ntawm demagnetization nkhaus, qhov me dua qhov poob ntawm lub cev muaj zog.
(7) Qhov siab dua qhov kev tiv thaiv ntawm cov hlau nplaum ruaj khov ferrite, qhov me dua qhov hws poob.
(8) Qhov kub coefficient ntawm cov hlau nplaum ruaj khov ferrite yog me me, thiab nws muaj qhov kub thiab txias stability ntawm qhov kub thiab txias.
Plaub, kev txhim kho ntawm cov pobzeb sib nqus hloov raws li qhov xav tau ntawm lub tshuab hlau nplaum ruaj khov nws tus kheej.
Cov hlau nplaum tas mus li tau muab faib ua cov hlau nplaum ruaj khov DC motors thiab cov hlau nplaum ruaj khov AC motors.
1. Cov hlau nplaum tas mus li AC lub cev muaj zog yog hais txog ntau theem synchronous lub cev muaj zog nrog cov hlau nplaum ruaj khov rotor, feem ntau yog siv ferrite thiab AlNiCo sib nqus vuas. Tsawg tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, thiab tam sim no NdFeB cov vuas sib nqus tau dav siv nyob rau hauv lub tshav pob ntawm high-power synchronous motors thiab generators. Tau kawg, vim muaj nuj nqis hauv ntiaj teb tsis tshua muaj peev txheej ntawm NdFeB cov vuas sib nqus, tus nqi ntawm cov khoom siv raw tau nce ob npaug, thiab nws cov nqi tsim khoom thiab cov khoom lag luam yuav nce ntxiv rau yav tom ntej, uas yuav cuam tshuam rau nws cov kev siv loj hauv qee qhov qis- kawg teb. NdFeB hlau nplaum nws tus kheej muaj qhov tsis zoo ntawm qhov kub thiab txias, uas txwv nws daim ntawv thov hauv lub sijhawm kub.
2. Cov hlau nplaum tas mus li DC motors tau muab faib ntxiv rau hauv brushless motors thiab zoo tib yam DC motors nrog commutators. Kev txiav txim los ntawm cov duab ntawm cov hlau nplaum thiab cov naj npawb ntawm cov ncej, nws cov ntawv thov feem ntau yog 2- ncej thiab 4- ncej ntawm cov DC motors zoo tib yam, thiab cov nplais sib nqus hauv paus, nws yog siv los ua lub cev muaj zog stator. Feem ntau ntawm cov me me DC motors siv ferrite magnetic vuas, uas yog siv rau hauv cov khoom ua si, khoom siv hauv tsev, thiab tsheb. Thaum lub cev tsis muaj zog siv cov nplais sib nqus ua lub stator, nws feem ntau tshaj li 6 tus ncej, yog li nws lub kaum sab xis yog me dua li ntawm DC lub cev muaj zog. Txawm li cas los xij, thaum cov pobzeb sib nqus siv los ua lub rotor ntawm lub cev tsis muaj zog, nws tuaj yeem muaj ntau tshaj 4 tus ncej. Rau 4 tus ncej, sab nrauv ntawm lub rotor yog magnetized, thiab txij li lub hauv paus lub kaum sab xis yog ze li ntawm 90 degree los ua ib lub voj voog, qhov no tuaj yeem paub qhov txawv. rau DC motors zoo tib yam.
3. Cov vuas sib nqus muaj cov kev xav tau sib txawv rau kev ua haujlwm thiab sib nqus teb waveform raws li daim ntawv thov sib txawv.
Thib tsib, yog cov txheej txheem ntau lawm. Nyob ntawm cov khoom siv thiab hom pobzeb sib nqus, cov craftsmanship kuj txawv heev.
ferrite sib nqus vuas feem ntau yog sintered ferrite, thiab NdFeB cov vuas sib nqus tau muab faib ua ob hom: sintered thiab bonded.
1. Qhia cov txheej txheem ntawm kev ntub dej ntawm kev sib deev
Cov txheej txheem ntub dej ntws yog cov khoom siv raw--- ua ntej kub kub thiab ntxhib crushing (thib ob lub pob milling)--- batching theem nrab pob milling (ntub milling)---magnetic teb sib sau--- sintering sib tsoo--- ntxuav--- magnetization. Vim hais tias cov molding slurry muaj noo noo, molding hais nyob rau hauv magnetic teb yog yooj yim tig, yog li ib tug ntau dua kev taw qhia yuav tau txais ntau dua qhuav nias, thiab nws cov kev ua tau zoo kuj yog siab dua.
2. Sintered NdFeB sib nqus pobzeb: batching---melting--- tawg cib hmoov magnetic teb ua---isostatic nias--- nqus sintering thiab tempering--- hlau txiav thiab lwm yam kev ua haujlwm---electroplating--- -Magnetizing
