Txhua yam khoom siv hluav taws xob, suav nrog cov khoom siv lub cev muaj zog, tau kawg, teev cov ntsuas hluav taws xob rau nws cov haujlwm ib txwm muaj.Ib qho kev sib txawv ntawm qhov hluav taws xob yuav ua rau muaj qhov tsis zoo rau kev ua haujlwm ntawm cov khoom siv hluav taws xob.

Rau cov cuab yeej siv high-end, cov cuab yeej tiv thaiv tsim nyog tau siv.Thaum lub hwj chim mov voltage yog txawv txav, lub hwj chim mov raug txiav tawm rau kev tiv thaiv.Rau cov cuab yeej meej heev, qhov hluav taws xob tsis tu ncua yog siv rau kev hloov kho.Cov khoom siv lub cev muaj zog, tshwj xeeb tshaj yog rau cov khoom lag luam muaj zog, qhov ua tau ntawm kev siv cov khoom siv hluav taws xob tas li yog qhov me me, thiab muaj ntau qhov kev tiv thaiv hluav taws xob.

Rau ib-theem lub cev muaj zog, tsuas muaj ob qhov xwm txheej ntawm high voltage thiab low voltage, thaum rau peb-theem lub cev muaj zog, kuj muaj qhov teeb meem ntawm qhov voltage.Qhov ncaj qha tshwm sim ntawm kev cuam tshuam ntawm peb qhov kev sib txawv ntawm qhov hluav taws xob yog qhov nce tam sim no lossis qhov tsis txaus ntseeg tam sim no.

Cov txheej txheem ntawm lub cev muaj zog qhia tias lub sab sauv thiab qis sib txawv ntawm qhov ntsuas hluav taws xob ntawm lub cev muaj zog tsis tuaj yeem tshaj 10%, thiab lub zog ntawm lub cev muaj zog yog proportional rau lub square ntawm lub cev muaj zog davhlau ya nyob twg voltage.Thaum qhov voltage siab dhau lawm, cov tub ntxhais hlau ntawm lub cev muaj zog yuav nyob rau hauv lub xeev ntawm magnetic saturation, thiab cov stator tam sim no yuav nce.Nws yuav ua rau muaj cua sov loj ntawm winding, thiab txawm tias qhov teeb meem zoo ntawm winding hlawv;thiab rau cov ntaub ntawv uas tsis tshua muaj voltage, ib tug yog hais tias tej zaum yuav muaj teeb meem nrog lub pib ntawm lub cev muaj zog, tshwj xeeb tshaj yog rau lub cev muaj zog khiav nyob rau hauv load, nyob rau hauv thiaj li yuav ua tau raws li lub load khiav ntawm lub cev muaj zog, qhov tam sim no kuj yuav tsum tau nce, thiab cov qhov tshwm sim ntawm qhov nce tam sim no kuj yog qhov cua sov thiab txawm tias kub hnyiab ntawm windings, tshwj xeeb tshaj yog rau kev ua haujlwm ntev-voltage, qhov teeb meem loj dua.

Unbalanced voltage ntawm peb-theem lub cev muaj zog yog ib qho teeb meem ntawm kev siv fais fab.Thaum lub voltage tsis sib npaug, nws yuav inevitably ua rau unbalanced motor tam sim no.Qhov cuam tshuam tsis zoo ntawm qhov tsis sib npaug ntawm qhov hluav taws xob tsim hluav taws xob sib nqus hauv lub cev muaj zog cua qhov sib txawv uas tawm tsam lub rotor tig.Ib qho me me tsis zoo ib ntus hauv qhov hluav taws xob yuav ua rau tam sim no los ntawm winding kom loj dua thaum qhov hluav taws xob sib npaug.Qhov zaus ntawm qhov tam sim no ntws hauv cov rotor tuav yog yuav luag ob npaug ntawm qhov ntsuas zaus, yog li qhov tam sim no squeezing nyhuv nyob rau hauv cov rotor tuav ua rau qhov poob ntawm rotor windings ntau loj dua li ntawm stator windings.Qhov kub nce ntawm stator winding yog siab dua li thaum ua haujlwm ntawm qhov hluav taws xob sib npaug.

Thaum qhov hluav taws xob tsis sib npaug, qhov chaw torque, qhov tsawg kawg nkaus torque thiab siab tshaj plaws torque ntawm lub cev muaj zog yuav raug txo.Yog tias qhov tsis sib xws ntawm qhov hluav taws xob loj heev, lub cev muaj zog yuav tsis ua haujlwm zoo.

Thaum lub cev muaj zog khiav ntawm tag nrho cov load nyob rau hauv unbalanced voltage, txij li thaum lub swb nce nrog qhov nce ntawm qhov ntxiv poob ntawm lub rotor, qhov ceev yuav txo me ntsis nyob rau lub sij hawm no.Raws li qhov voltage (tam sim no) tsis sib npaug nce, lub suab nrov thiab kev vibration ntawm lub cev muaj zog tuaj yeem nce ntxiv.Kev vibration tuaj yeem ua rau lub cev muaj zog lossis tag nrho lub cev tsav.

Txhawm rau txhawm rau txheeb xyuas qhov ua tau zoo ntawm qhov tsis sib xws ntawm lub cev muaj zog, nws tuaj yeem ua los ntawm kev siv hluav taws xob ntsuas hluav taws xob los yog qhov hloov pauv tam sim no.Cov cuab yeej siv feem ntau yog nruab nrog lub ntsuas ntsuas hluav taws xob, uas tuaj yeem txheeb xyuas los ntawm cov ntaub ntawv sib piv.Rau cov ntaub ntawv uas tsis muaj cov cuab yeej saib xyuas, yuav tsum tau siv qhov ntsuas tsis tu ncua lossis ntsuas tam sim no.Nyob rau hauv cov ntaub ntawv ntawm dragging cov cuab yeej, ob-theem fais fab mov kab yuav arbitrarily pauv, tam sim no hloov tau pom, thiab qhov voltage tshuav nyiaj li cas yuav soj ntsuam indirectly.
