Nyob rau hauv lub ntsiab lus ntawm kev hloov pauv thoob ntiaj teb kev lag luam mus rau kev ua haujlwm zoo, kev txuag hluav taws xob thiab kev txo nqi, cov cav asynchronous tau maj mam hloov cov cav slip ring ib txwm muaj nyob rau hauv ntau qhov chaw lag luam, ua lub hauv paus tseem ceeb rau kev tsim khoom lag luam thiab kev txhim kho. Qhov kev hloov pauv no tsis yog tsuas yog ua kom zoo dua qhov kev ua haujlwm ntawm cov tuam txhab lag luam xwb tab sis kuj pab txo cov nqi tsim khoom, cim ib theem tshiab hauv kev txhim kho cov khoom siv hluav taws xob kev lag luam.
Muaj kev tshaj tawm tias cov cav slip ring tau siv dav hauv cov xwm txheej kev lag luam hnyav xws li metallurgy, mining thiab tshuaj lom neeg vim lawv qhov zoo hauv kev pib hnyav thiab kev tswj hwm qhov ceev. Txawm li cas los xij, nrog kev txhim kho tas mus li ntawm cov kev xav tau ntawm kev tsim khoom hauv kev lag luam, cov kev txwv ntawm cov cav slip ring tau dhau los ua qhov tseem ceeb.
Cov neeg sab hauv kev lag luam tau taw qhia tias cov cav tov ib txwm muaj cov qauv nyuaj, suav nrog cov khoom tseem ceeb xws li cov nplhaib nplua thiab cov txhuam carbon. Cov khoom no yooj yim hnav thiab rhuav thaum lub sijhawm ua haujlwm ntev, xav tau kev tshuaj xyuas tsis tu ncua, kev saib xyuas thiab hloov pauv. Tus nqi txij nkawm siab, lub sijhawm tsis ua haujlwm ntau zaus thiab muaj kev phom sij rau kev nyab xeeb (xws li cov hluav taws xob los ntawm kev sib cuag tsis zoo) tau dhau los ua cov yam tseem ceeb uas txwv tsis pub ua haujlwm zoo ntawm cov tuam txhab.
Vim yog qhov no, cov cav tov asynchronous (tshwj xeeb tshaj yog cov cav tov asynchronous squirrel-cage) tau maj mam dhau los ua qhov kev xaiv zoo tshaj plaws rau cov lag luam kev lag luam vim lawv cov txiaj ntsig tshwj xeeb. Piv nrog cov cav tov slip ring, cov cav tov asynchronous muaj peb qhov zoo tseem ceeb hauv kev siv tiag tiag:
Ua ntej, tus nqi txij nkawm raug txo qis heev. Cov cav asynchronous muaj cov qauv yooj yim, tsis muaj cov khoom yooj yim hnav xws li cov nplhaib plam thiab cov txhuam carbon. Cov lag luam tsuas yog yuav tsum ua qhov kev tshuaj xyuas tsis tu ncua, uas txo qhov kev ua haujlwm txij nkawm thiab lub sijhawm tsis ua haujlwm, thiab zam kev cuam tshuam kev tsim khoom los ntawm kev ua tsis tiav ntawm cov khoom.
Qhov thib ob, kev ua haujlwm ruaj khov thiab muaj kev nyab xeeb dua. Cov cav asynchronous txais yuav kev sib kis tsis sib cuag, uas zam kev phom sij kev nyab xeeb xws li hluav taws xob thiab kev sib cuag tsis zoo los ntawm kev hnav ntawm cov cav slip ring. Lawv muaj kev hloov pauv zoo rau cov chaw ua haujlwm nyuaj xws li kub siab, av noo thiab hmoov av, thiab tus nqi ua tsis tiav qis dua li ntawm cov cav slip ring.
Qhov thib peb, tus nqi ua tau zoo dua. Cov txheej txheem tsim khoom ntawm asynchronous motors yog laus, tus nqi yuav khoom qis dua li ntawm slp ring motors, thiab tus nqi txij nkawm tom qab qis. Nws tuaj yeem ua tau raws li qhov xav tau hluav taws xob ntawm cov lag luam me thiab nruab nrab thiab cov xwm txheej tsim khoom hnyav, pab cov lag luam txo cov nqi ua haujlwm.
Ib tug neeg uas saib xyuas lub tuam txhab tshuaj lom neeg loj tau hais tias: "Tom qab hloov lub cev muaj zog qub nrog lub cev muaj zog asynchronous, qhov zaus txij nkawm ntawm cov khoom siv tau txo qis 60%, lub sijhawm cuam tshuam kev tsim khoom tau luv dua yuav luag ib nrab, thiab tus nqi ua haujlwm txhua xyoo tau txuag tau kwv yees li 30%. Lub tswv yim no tau lees paub los ntawm ntau lub tuam txhab uas tau ua tiav qhov kev hloov lub cev muaj zog.
Cov kws tshaj lij hauv kev lag luam kwv yees tias nrog kev nce qib tas mus li ntawm kev txawj ntse hauv kev lag luam thiab kev txuag hluav taws xob thiab txo cov pa phem, cov cav asynchronous yuav nthuav dav lawv cov xwm txheej siv, maj mam hloov cov cav slip ring hauv ntau qhov chaw lag luam. Yav tom ntej, nrog kev txhim kho tas mus li ntawm cov thev naus laus zis tswj lub cev muaj zog, kev ua haujlwm ntawm cov cav asynchronous yuav raug kho kom zoo dua, muab kev txhawb nqa zoo dua rau kev txhim kho zoo ntawm kev lag luam.
