Cov pa hluav taws xob ntawm cov qauv siv hluav taws xob muaj ntau qhov sib txawv los ntawm kev sib luag hauv txoj kev lawv tsim cov teb sib nqus. Tus Circuit Court rau hloov ntawm lub cev muaj zog, hom ntawm tam sim no thiab tus naj npawb ntawm cov theem rau nws lub zog hluav taws xob, nrog rau thaj tsam ntawm kev thov, nyob ntawm qhov no.
Cov Lus Qhia

Cov tsav tsheb DC lub cev muaj ob txoj hau kev. Yog tias koj siv lub ntsuas hluav taws xob tsis tu ncua rau nws ntawm qhov ntsuas qhov ntsuas ntawm tus ncej, nws yuav pib tig ntawm qhov kev ceev ceev hauv phau ntawv hla tebchaws. Txhawm rau kom txo nws, txo qis rau qhov tsis txaus (tab sis tsis ntau dhau, txwv tsis pub nws yuav nres thiab yuav hlawv tawm). Txhawm rau hloov qhov ceev ntawm lub cev muaj zog, thim rov qab qhov polarity ntawm qhov muab cov voltage. Lub zog muaj zog ntawm hom no tsis tuaj yeem hloov mus yam tsis muaj thauj khoom kom tsis txhob muaj kev puas tsuaj rau tus kheej los ntawm kev nce nrawm.

Lub tshuab tsav tsheb dav dav muaj peev xwm khiav ntawm ob qho DC thiab AC voltage. Qhov tos ntawm nws qhov kev sib hloov ceev ntawm qhov ntsuas hluav taws xob tsis yog kab, raws li nyob rau hauv lub cav saum toj no, tab sis qhia nyob rau hauv txoj kab nkhaus uas nyuaj. Thaum AC voltage raug thov, nws yuav tig ntawm tib zaus raws li thaum thov ntawm tib lub thauj khoom, DC voltage sib npaug rau AC rms tus nqi. Thaum muab cov khoom siv hluav taws xob ncaj qha, lub polarity thim rov qab ntawm lub tswv yim yuav tsis pauv qhov kev taw qhia kev sib hloov ntawm lub cev muaj zog. Nws tuaj yeem thim rov qab los ntawm kev hloov pauv qhov polarity ntawm kev sib txuas ntawm ob qho tib si stator, lossis tsuas yog cov khoom siv sib tsoo-sib dhos. Xws li lub cev muaj zog yog qhov nkag siab ntau tshaj rau cov overloads thiab tsis muaj thauj khoom hloov dua li ib qho dhau los.

Lub asynchronous peb-theem hluav taws xob lub cev muaj peev xwm tsuas muab tau nrog kev hloov pauv tam sim no. Ntawm nws qhov teeb meem, ob qhov tseem ceeb ntawm voltage tau qhia los ntawm cov feem: qhov me me yog rau kev tig mus nrog ib daim duab peb sab, thiab qhov loj dua yog rau kev tig mus nrog lub hnub qub. Hauv av lub cev muaj zog, txuas nws rau hauv peb-theem network, txuas cov cua kab nrog kab txiav lossis hnub qub, nyob ntawm tus nqi ntawm cov hluav taws xob loj, thiab tsis txuas rau xoom txhua qhov. Txhawm rau rov qab cov lub cev muaj zog no, tua nws, tso nws los rau qhov chaw nres kom tiav, thim ob ntu ntxiv, thiab tig rov qab.

Ib leeg-theem asynchronous motors tau muab faib ua ib leeg-winding thiab ob-winding. Hauv yav dhau los, txoj kev taw qhia ntawm kev sib hloov yog txiav txim siab los ntawm tus qauv tsim ntawm lub sib nqus shunt thiab tuaj yeem hloov mus rau tau. Xws li lub cev muaj zog ib zaug ntom nti, rau qhov uas nws txaus txuas rau lub network nrog qhov voltage thiab zaus qhia ntawm lub npe. Hauv ob-winding lub cev muaj zog, txuas lub winding nrog lub siab tsis kam rau lub network ncaj qha, thiab nrog lub zog me dhau los ntawm lub zog (tsim nyog ntawv), lub peev xwm thiab cov ntsuas hluav taws xob ntawm cov uas tau qhia ntawm lub cev muaj zog. Txhawm rau rov qab nws, koj yuav tsum pauv qhov kawg ntawm ob tog ntawm ob kab.
