Permanoy Alloy Hlau nplaum, raws li lub npe qhia meej qhia tau, yog tshwj xeeb alloys tsim los tswj cov khoom sib nqus ruaj khov tsis muaj kev xav tau ntawm lub zog sab nraud. Cov hlau nplaum no tau pom los ntawm lawv cov khoom sib nqus Qhov tshwj xeeb no ua rau lawv tsis tseem ceeb hauv ntau yam kev lag luam.
Hauv kev lag luam hluav taws xob, cov hlau nplaum tas mus li ua si lub luag haujlwm tseem ceeb hauv kev tiv thaiv ntau yam khoom siv. Hauv hluav taws xob cov tshuab hluav taws xob, piv txwv li, lawv yog cov khoom siv tseem ceeb. Cov khoom siv hauv tsev neeg zoo li cov khoom siv hauv tsev neeg, ntxhua khaub ncaws, thiab kiv cua cia siab rau cov hlau nplaum tas mus li hauv lub zog hluav taws xob. Lawv cov chaw sib nqus uas ruaj khov ua kom muaj kev lag luam du thiab ib txwm muaj zog ua haujlwm, txo kev co thiab suab nrov. Hauv cov khoom siv suab xws li cov neeg hais lus thiab lub mloog pob ntseg, cov hlau nplaum tas mus li tsim nyog rau cov sib nqus uas xav tau rau cov sib nqus rau cov sib nqus kom pom tseeb, yog li ua suab. Lub zog loj lub zog thiab kev ruaj khov ntawm cov hlau nplaum no ua rau muaj qib siab - falpic suab shoppuction, txhim kho kev mloog. Nyob rau hauv hard disk drives, cov hlau nplaum tas nrho yog siv los txhawb kev txav mus los ntawm kev nyeem - sau cov ntaub ntawv nkag mus thiab chaw ua haujlwm sai sai rau cov kev ua haujlwm zoo ntawm kev siv computer tshiab.
Kev ntsuas tsheb txhais tau cov txiaj ntsig zoo heev los ntawm kev siv cov hlau nplaum tag nrho. Hauv hluav taws xob thiab cov tsheb hybrid, cov khoom siv hlau nplaum tas mus li (pmsms) tau ua nrov ntau dua. Cov motors no suav cov hlau nplaum thoob plaws hauv lawv cov rotors, muab cov khoom siv hluav taws xob ntau ntxiv piv rau cov khoom siv Induction Induction. Kev siv cov hlau nplaum tas li Qhov no tsis tsuas yog txo qhov hnyav tag nrho ntawm lub tsheb tab sis kuj ua rau muaj kev txhawb nqa thiab ua tau zoo dua. Ib qho ntxiv, cov hlau nplaum tas mus li yog siv hauv cov cav ntsuas hluav taws xob, xws li lub log ceev sensors thiab txoj kev tswj hwm. Cov sensors cia siab rau cov sib nqus ntawm cov hlau nplaum sib nqus ntawm cov hlau nplaum tas nrho kom pom kev txav mus los thiab txoj haujlwm ntawm kev nyab xeeb thiab kev ua haujlwm zoo ntawm lub tsheb.
Saib tom ntej, kev txhim kho cov hlau nplaum tag nrho yog tsom rau txhim kho ob qho kev ua tau zoo thiab kev ruaj khov. Cov kws tshawb nrhiav tau niaj hnub tshawb xyuas cov khoom lag luam tshiab tshiab los txhim kho cov khoom sib nqus ntawm cov hlau nplaum sib txawv. Piv txwv li, kev siv zog tau ua kom nce cov khoom sib nqus khoom, uas yog qhov taw qhia tseem ceeb ntawm cov hlau nplaum lub zog. Cov khoom lag luam muaj zog dua yuav ua rau kev tsim cov me dua muaj cov khoom siv hluav taws xob ntau dua hauv ntau yam kev siv. Hais txog kev ruaj khov, muaj ib qho kev tsav tsheb loj zuj zus los txhim kho cov hlau nplaum tag nrho uas txo qis kev siv cov khoom tsis tshua muaj nqi thiab kim. Raws li qhov kev thov rau cov hlau nplaum tas li tseem nce thoob plaws hauv kev lag luam, cov kev nce qib no yuav yog qhov tseem ceeb rau kev sib ntsib ntawm technology.
