Ama-motor ane-voltage ephezulu yesigaba sesithathu awuhlobo lwama-motor e-AC asetshenziswa kabanzi ezinhlotsheni ezahlukene zezimboni ngenxa yezinzuzo zawo eziningi zobuchwepheshe. Njengoba ekwazi ukukhiqiza i-torque ephezulu ngesivinini esiphansi, lolu hlobo lwe-motor lufanele imishini esindayo. Kulesi sihloko, sixoxa ngezinzuzo zobuchwepheshe zama-motor ane-voltage ephezulu yesigaba sesithathu.
ukusebenza kahle okuphezulu
Enye yezinzuzo eziyinhloko zama-motor ane-voltage ephezulu yezigaba ezintathu ukusebenza kahle okuphezulu. Lawa ma-motor asebenza ngama-voltage aphezulu, okusho ukuthi adinga ugesi omncane ukuze akhiqize amandla afanayo. Lokhu kuholela ekulahlekelweni kwamandla amancane kanye nezindleko zokusebenza eziphansi. Ngaphezu kwalokho, ama-motor ane-voltage ephezulu yezigaba ezintathu aguqula amandla kagesi abe amandla omshini ngendlela ephumelela kakhulu, okuholela ekusebenzeni okungcono kakhulu.
nciphisa ukulungiswa
Amamotha ane-voltage ephezulu yesigaba sesithathu ngokuvamile anezingxenye ezimbalwa kunezinye izinhlobo zamamotha, okwenza kube lula ukuwanakekela. Aphinde akhiqize ukushisa okuncane nokudlidliza okuncane, okusho ukuthi agugile futhi adabuke kancane ngokuhamba kwesikhathi. Ngaphezu kwalokho, lawa mamotha asebenzisa amafutha amancane kunezinye izinhlobo zamamotha, okunciphisa isidingo sokulungiswa njalo.
Thuthukisa amandla
Ama-motor ane-voltage ephezulu yesigaba sesithathu ane-power factor ephezulu, okusho ukuthi angcono ekuguquleni amandla kagesi abe amandla omshini. Lokhu kwandisa ukusebenza kahle kwenjini futhi kunciphisa amandla alahlekela ekushiseni.
ukulawula okungcono
Ama-motor ane-voltage ephezulu anezigaba ezintathu avumela ukulawula okungcono isivinini kanye nesiqondiso semoto. Lokhu kungenxa yokuthi asebenza ngogesi onezigaba ezintathu, okuvumela ukulawula okunembe kakhudlwana ukusebenza kwemoto. Ngaphezu kwalokho, lawa ma-motor angalawulwa kusetshenziswa ama-variable frequency drive (ama-VFD), avumela ukulawula okunembe kakhudlwana isivinini kanye nesiqondiso semoto.
amandla amakhulu okukhipha
Ama-motor ane-voltage ephezulu yesigaba sesithathu ayakwazi ukukhiqiza amandla amaningi kunezinye izinhlobo zama-motor. Lokhu kungenxa yokuthi angakwazi ukusingatha ama-voltage aphezulu kanye nemisinga, okuwavumela ukuthi akhiqize i-torque namandla amaningi. Lokhu kuwenza afaneleke kakhulu emishinini esindayo kanye nasezindaweni zezimboni ezidinga amandla aphezulu.
Ekuphetheni
Ngamafuphi, ama-motor e-AC anezigaba ezintathu anezinzuzo eziningi zobuchwepheshe kunezinye izinhlobo zama-motor. Asebenza kahle kakhulu, adinga ukulungiswa okuncane, futhi anikeza ukulawula okungcono kanye nokukhipha amandla. Ngenxa yokusebenza kwawo okuhle kakhulu kanye nokuthembeka, lawa ma-motor asetshenziswa kabanzi ezinhlotsheni ezahlukene zezimboni. Uma udinga i-motor yemishini esindayo noma yezimboni, i-motor enezigaba ezintathu ingase ibe yisinqumo esingcono kakhulu sezidingo zakho.
