Hauv qee cov ntu ntawm lub tsheb niaj hnub, siv lub tshuab hluav taws xob, thiab thaum kho thiab kho tsheb, feem ntau tsis tuaj yeem ua yam tsis muaj lub tshuab hluav taws xob uas tsav ntau yam khoom siv pabcuam. Rau kev ua haujlwm siab, lub cav yuav tsum raug txuas nrog thiab teeb tsa. Cov txheej txheem kev sib txuas yog txiav txim siab, ua ntej txhua yam, los ntawm hom hluav taws xob thiab nws cov qauv tsim.

Cov Lus Qhia
Kauj ruam 1
Nrhiav qhov xaus ntawm lub cev muaj zog windings. Nyob ntawm seb hom twg, lawv tuaj yeem txuas nrog lub block nrog peb lossis rau qhov kawg. Yog tias cov cuab yeej muaj peb qhov kawg, siv daim ntawv sib txuas lossis cov hnub qub sib txuas. Nrog rau lub davhlau ya nyob twg, kev tiv thaiv winding tsis txuas nrog txhua lwm.
Kauj ruam 2
Txuas qhov kawg ntawm cov kab hlau nrog "hnub qub" yog tias cov lus qhia kev siv lub tshuab ua haujlwm tau qhia tias cov cua ntsawj yog tsim los rau kev ua haujlwm ntawm 220 V. uas qhia tau tias lawv tuaj yeem siv hauv kev sib txuas nrog voltage ntawm 220/380 V.
Kauj ruam 3
Thaum txuas lub tshuab hluav taws xob raws li hom "lub hnub qub", nrhiav qhov kawg ntawm windings ntawm tib lub npe thiab muab lawv txuas rau hauv ib qho thiaj li hu ua "zero" taw tes. Feem ntau, hom kev sib txuas ntawm cov kab hlau tsis yooj yim.
Kauj ruam 4
Siv cov khoom siv sib txuas ntawm cov cua ntsawj ua kom zoo, sib txuas ntawm qhov kawg ntawm thawj lub tshuab qoj cua nrog qhov pib ntawm kev sib hloov ntawm qhov thib ob, qhov kawg ntawm qhov thib ob nrog thaum pib ntawm peb, thiab tom qab ntawd txuas tus pib ntawm thawj winding mus rau thaum xaus ntawm qhov thib peb. Siv cov ntawv cim hlau rau kab txhawm rau txhawm rau nrhiav kab windings.
Kauj ruam 5
Yog tias tsis muaj tus cim ntaus cim, thiab cov ntaub ntawv pov thawj rau lub cev tsis muaj lossis tsis ploj, siv lub tshuab ntsuas kom txiav txim siab qhov kawg ntawm kev sib tw, hloov nws mus rau ohmmeter hom. Raug xwm txheej sau cov cim rau cov zauv nrog tus xov tooj lossis insulating kab xev ntawm cov xim sib txawv.
Kauj Ruam 6
Txhawm rau kom nrhiav qhov kawg ntawm cov kab windings, txuas rau qhov xwm yeem ib qho ntawm ob kab thiab muab lub zog ntawm tsawg kawg 6V rau lawv. Txuas tus xov tooj voltmeter mus rau qhov seem thib peb winding.
Kauj Ruam 7
Txheeb xyuas nrog voltmeter yog tias muaj AC voltage hauv Circuit Court. Cov hluav taws xob tsis txaus txhais tau hais tias thawj ob kab hlau txuas nrog hauv kev rov qab. Hauv qhov no, cov lus xaus ntawm cov thawj winding thim rov qab, muaj yav tas los cim qhov pib thiab xaus ntawm windings.
Kauj ruam 8
Rov ua dua qhov kev ua tau piav qhia, tab sis nrog cov thib ob thiab thib peb windings ntawm lub tshuab hluav taws xob. Qhov no yuav tso cai koj los nrhiav qhov pib thiab xaus ntawm qhov thib peb winding.
Kauj Ruam 9
Tom qab txuas cov windings, txuas lub tshuab hluav taws xob mus rau lub zog muab hluav taws xob thiab xyuas cov cuab yeej rau kev ua haujlwm. Thaum lub sij hawm tshuaj ntsuam, nws yuav pom tias cov kev taw qhia ntawm kev sib hloov ntawm lub cev muaj zog yog tsis muaj tseeb. Kho qhov teeb meem no los ntawm kev sib hloov cov xov hluav taws xob ntawm lub zog hluav taws xob thiab lub stator winding.
