Cov yam ntxwv ntawm cov khoom siv tas li hlau
3.5 Corrosion tsis kam
Qhov teeb meem ntawm yooj yim corrosion ntawm NdFeB cov ntaub ntawv muaj ib tug zoo cawv rau qhov zoo ntawm lub cev. Tam sim no, nws qhov teeb meem kev tiv thaiv qhov teeb meem tsis tau raug kho zoo hauv Suav. Cov txheej txheem plating uas siv los ntawm txoj kev ua rau feem ntau ua rau txheej plhaws ntog tawm thiab lub cev quab yuam. Tsis tas li ntawd, lub peev xwm los tiv thaiv tej yam tshwj xeeb puag ncig (xws li cov av noo, cov tshuaj tua ntsev thiab cov roj cua tshwj xeeb), uas cuam tshuam lub peev xwm ntawm lub cev kom ua raws li qhov tshwj xeeb puag ncig. Nws yog vam hais tias cov khoom siv hlau nplua nuj yuav muaj kev txhim kho ntxiv hauv kev tiv thaiv npoo av.
3.6 Kev ruaj ntseg kev ua tau zoo, tsis sib xws, sib xws
Yuav kom ntseeg tau tias qhov kev ua ntawm lub tshuab tsis hloov loj heev thaum lub neej ua neej, tshwj xeeb tshaj yog rau qee cov tub rog kev ua haujlwm nrog cov kev cai tshwj xeeb, kev ua haujlwm tau zoo ua haujlwm tau ntev dua 15 xyoos. Nws yog vam hais tias cov khoom sib nqus ntawm cov khoom siv hlau nplaum tas li yuav nyob ruaj khov mus ntev.
Motors, tshwj xeeb tshaj yog cov cav ua kom siab, yuav tsum tau muaj cov khoom sib nqus khoom sib nqus thiab sib luag ntawm cov khoom siv hlau nplaum tas li. Cov nyhuv tsis muaj hlau nplaum yuav ua rau tsis sib luag ntawm lub cav, tsis muaj zog ntxiv torque ripple, muaj cov zis hluav taws xob khiav tawm ntawm cov generator, tsis muaj tseeb, thiab txo cov neeg ua haujlwm ntawm kev tswj lub cev. Tsis tas li ntawd, cov khoom sib nqus ntawm cov qub qib ntawm cov khoom siv hlau nplaum ntawm cov khoom sib txawv nyias txawv nyias, qee zaum ua rau lub cav tsis poob hauv cov khoom siv. Yog li no, lub siab lub zog yuav tsum tau hais tias cov khoom sib nqus ntawm cov khoom siv hlau nplaum tas li muaj qhov ua tau zoo li ntawm 5%, thiab qhov teeb meem tsis sib xws yog li ntawm 3%.
3.7 ua haujlwm tshuab
Tseem muaj ntau qhov teeb meem ntawm kev ua lag luam ntawm cov tshuab hluav taws xob txuas mus tas li, uas muaj nqis kawm. Piv txwv li, yuav ua li cas kom tus txheej txheem tsis muaj nyob hauv txoj kev ua ke yuav cuam tshuam rau cov khoom sib nqus. Seb qhov teeb meem, kev ua kom vauv thiab kev ua haujlwm thaum lub sij hawm ua tus txheej txheem muaj feem xyuam rau cov khoom sib nqus, thiab yuav ua li cas coj kev tiv thaiv nrog cov khoom sib nqus hauv cov txheej txheem ntawm kev lag luam thiab thaum lub sijhawm sib dhos.
Cov hlau nplaum nyob hauv cov hlau nplaum tas li ntawm cov hlau nplaum tas li yog cov khoom siv hlau nplaum, uas ua rau kom tsis muaj teeb meem ntawm cov cav ntoo, tab sis ua rau cov kev lag luam muaj kev nyuab, xws li cov hlau nplaum sab nraud thiab cov tshuab hluav taws xob sib txuas. Cov hlau nplaum uas sib txuam ntau yog txuas ncaj qha mus rau saum npoo av ntawm lub rotor nto. Kev siv cov sintered high-performance NdFeB yog qhov nyuaj thiab cov txheej txheem khiav lag luam yog qhov nyuaj. Thaum txoj kev sib hloov ceev siab, qhov kev ruaj ntseg yuav tsis zoo rau. Yog hais tias lub sintered hlau nplaum yuav ua rau hauv kev siv hluav taws xob siv ntau npu ntawm tus qauv, cov txheej txheem tsim ntawm lub rotor motor yuav tsum yooj yim heev. Bonding magnets yuav ua tau tam sim no, tab sis cov khoom sib nqus tsis siab. Xws li cov hlau nplaum sintered yuav tsum paub thiab yuav muab nkag rau hauv cov khoom siv thiab cov nqi tsis siab (nws yog qhia tias tuam ntxhab tau nqa tawm qhov kev tshawb fawb no), nws yuav muaj kev cia siab yav tom ntej.
Xaus
Nyob rau hauv kev xaus, kev tsim cov ntaub ntawv magnet tas mus li tau nce kev tsim cov cav ntoo kom ruaj khov, thiab daim ntawv thov kom tau cov txuj ci tas mus li thiab cov khoom yuav tsum tau muaj rau cov ntawv magnet kom zoo ntxiv. Nrog cov hlau nplaum hluav taws xob siv rau hauv av av, aerospace, kev tiv thaiv, kev ua haujlwm thiab kev ua liaj ua teb thiab kev ua liaj ua teb txhua txhua hnub, daim ntawv thov cov khoom ntiag tug hauv cov cav yuav tsum muaj ntau heev.
