Kev siv hluav taws xob motors

Feem ntau siv los ntawm ntau lub tshuab hluav taws xob yog AC asynchronous lub cev muaj zog (tseem hu ua induction motor). Nws yog ib qho yooj yim mus use, txhim khu kev qha rau kev khiav lag luam, pheej yig, thiab structurally sturdy, tab sis muaj ib tug tsawg zog yam tseem ceeb thiab nyuaj ceev tswj. Lub peev xwm loj thiab lub zog qis qis feem ntau siv cov motors synchronous (saib synchronous motors). Synchronous motors tsis tsuas yog muaj lub zog loj, tab sis lawv qhov ceev yog ywj siab ntawm qhov loj me thiab tsuas yog nyob ntawm daim phiaj zaus. Kev ua haujlwm kuj ruaj khov. DC motors feem ntau yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau muaj ntau yam ceev kev tswj. Tab sis nws muaj ib tug commutator, uas yog complex nyob rau hauv cov qauv, kim nyob rau hauv tus nqi, nyuaj rau tswj, thiab tsis haum rau hnyav ib puag ncig. Tom qab xyoo 1970, nrog rau kev tsim hluav taws xob hluav taws xob thev naus laus zis, kev tswj hwm kev ceev ntawm AC motors tau maj mam loj hlob, thiab cov khoom siv tau txo qis, uas tau pib siv. Qhov siab tshaj plaws cov khoom siv hluav taws xob uas lub cev muaj zog tuaj yeem tiv taus raws li qhov kev ua haujlwm tau teev tseg (nruam, luv luv, sib cuam tshuam lub voj voog) yam tsis ua rau overheating ntawm lub cev muaj zog hu ua nws lub zog ntsuas. Thaum siv nws, yuav tsum xyuam xim rau cov kev cai ntawm daim ntawv teev npe. Thaum lub cev muaj zog khiav, kev saib xyuas yuav tsum tau them nyiaj rau kev sib piv nws cov yam ntxwv ntawm lub cev muaj zog kom tsis txhob muaj kev nrawm lossis nres. Lub tshuab hluav taws xob muaj peev xwm muab tau ntau lub zog, txij li milliwatts mus txog kaum txhiab kilowatts. Kev siv thiab tswj cov tshuab hluav taws xob yog qhov yooj yim heev, nrog lub peev xwm pib tus kheej, nrawm, nres, thim rov qab, thiab tuav. Lub zog tso zis ntawm lub tshuab hluav taws xob dav dav sib txawv nrog qhov nrawm thaum tswj kev ceev.
