Permanent Magnet Motors: Feem ntau ua txhaum thiab teeb meem hauv kev ua haujlwm

Piv nrog cov pa motors,ruaj khov hlau nplaum motorsyog tus tshiab nyob rau hauv ntau lub teb. Ua tsaug rau lawv lub zog muaj zog- txuag tau qhov zoo thiab kev ua haujlwm zoo ntawm ob qho tib si siab thiab qis qis, lawv tau dhau los ua qhov kev xaiv zoo rau cov neeg siv khoom thiab tau txais kev txhawb zog ib zaug rau ntau qhov chaw thov hauv xyoo tas los no.

Txawm li cas los xij, nws kuj tseem muaj qhov tsis xws luag: qhov pheej hmoo ntawm demagnetization. Tsis tas li ntawd, qee cov tuam txhab lag luam tsis muaj peev xwm txhob txwm siv cov qib qis- cov hlau nplaum ruaj khov kom nrhiav tau cov txiaj ntsig siab, ua rau muaj qhov sib txawv loj hauv kev ntseeg tau ntawmruaj khov hlau nplaum motorsntawm kev ua lag luam. Qee qhov kev ua haujlwm qeeb qeeb dhau sijhawm, thaum lwm tus raug kev txom nyem los ntawm kev demagnetization thoob plaws. Ntawm no, peb tsom mus rau qhov teeb meem demagnetization rau kev siv thiab kev tshuaj xyuas thaum cov neeg siv ntsib teeb meem cuam tshuam.

DemagnetizationQhov teeb meem no tuaj yeem tshwm sim yog tias qhov kev xam tsim tsis raug thiab qis - cov khoom siv hlau nplaum raug xaiv. Overheating demagnetization yog ib lub ntsiab lus rhiab heev; degraded magnetic zog ntawm cov hlau nplaum kuj tuaj yeem ua rau overcurrent thiab overheating. Thaum lub sijhawm ua haujlwm tam sim no tshaj qhov demagnetization tsis kam ntawm cov hlau nplaum, irreversible demagnetization ntawm cov hlau nplaum yuav tshwm sim.

Sib tham sib Deterioration ntawm Magnetic Properties thiab tam sim no DemagnetizationQhov no yog ib qho kev txhawj xeeb tseem ceeb hauv daim ntawv thov ntawm cov motors. Thaum cov khoom sib nqus tsis zoo thaum lub sijhawm ua haujlwm, lub cev muaj zog tam sim no yuav surge instantaneously, ua rau overheating hnyav. Qhov no ntxiv degrades cov khoom sib nqus ntawm cov hlau nplaum, uas nyob rau hauv lem drives lub tam sim no sawv dua. Lub voj voog sib cuam tshuam no tuaj yeem ua rau lub cev tsis ua haujlwm hauv lub sijhawm luv luv.

Magnet DetachmentIn sib dhos tiag tiag, cov hlau nplaum yog tsau rau hauv cov tub ntxhais nrog cov nplaum, thiab cov nplaum nplaum yog ntim ntawm cov hlau nplaum ruaj khov los txhim kho kev sib raug zoo thiab tiv thaiv cov hlau nplaum los ntawm ya tawm vim yog lub zog centrifugal thaum lub sij hawm siab - kev sib hloov ceev. Magnet detachment tuaj yeem tshwm sim nyob rau hauv kev sib xyaw ua ke ntawm kev ua haujlwm tsis zoo ntawm cov nplaum nplaum, tsis muaj kev ruaj ntseg, qhov kub thiab txias ntau dhau, dej nkag los yog cov av noo siab hauv cov kab noj hniav, ua rau muaj kev sib txhuam ncaj qha thiab tsis ua haujlwm ntawm lub cev muaj zog.

Lub demagnetization tshwm sim los ntawm cov saum toj no sab hauv thiab sab nraud yam yog txwv rau lub cev muaj zog nws tus kheej. Hauv kev xyaum,ruaj khov hlau nplaum motorsyuav tsum tau nruab nrog tshwj xeeb - lub hom phiaj zaus converters thaum ua haujlwm. Qhov kev ua tau zoo ntawm cov zaus hloov pauv kuj tseem muaj feem cuam tshuam rau cov hlau nplaum ruaj khov, thiab kev tiv thaiv demagnetization feem ntau yog nyob ntawm kev tswj software, uas nws cov txheej txheem yog raws li kev sib tham saum toj no thiab yuav tsis piav qhia ntxiv. Cov ntsiab lus tseem ceeb tau txais tos rau kev sib tham tshwj xeeb yav tom ntej.
