Okweinjini yesigaba ezintathu, i-stator winding inezinhlobo ezimbili zokuxhuma, unxantathu nenkanyezi, uxhumano lwenkanyezi luhlanganisa umsila we-three-phase winding ndawonye, futhi ikhanda le-three-phase winding lixhunywe nokunikezwa kwamandla; Indlela yokuxhuma inkanyezi inezimo ezimbili zokuxhumeka kwe-alien kanye nokuxhumeka kwangaphakathi, i-internal star connection motor iyi-star point exhunywe ne-three-phase winding ibekwe engxenyeni efanele ye-stator winding, kuneziphetho ezintathu zokuphuma eziphumayo, kanti uxhumano lwe-alien luyikhanda nomsila we-three-phase winding konke kuholwa ngaphandle, futhi uxhumano lwangaphandle kanye nezintambo zemoto.
Indlela yokuxhumanisa engunxantathu iwukuxhumanisa ikhanda le-phase winding nomsila we-phase winding enye, okungukuthi, i-U1 ne-W2, i-V1 ne-U2, i-W1 ne-V2, bese indawo yokuxhumanisa ixhunywe kugesi.
Uma ukugoqa kwesigaba ngasinye kubhekwa njengomugqa, ngemva kokuba izinkanyezi zixhunyiwe, kufana nenkanyezi ekhanyayo, kanti umthetho wokuxhuma unxantathu ufana nonxantathu, ngakho-ke ubizwa ngokuthi uxhumano lwenkanyezi noma uxhumano lonxantathu. Singaxhuma futhi imoto engunxantathu ezimweni ezimbili ze-Angle yangaphakathi kanye ne-Angle yangaphandle.
Uma kuyimoto ene-voltage eyodwa, kokubili ngaphakathi nangaphandle kungaxhunywa, kodwa kumoto ene-voltage ezimbili, kungadonswa ikhanda nomsila kuphela we-winding yesigaba sesithathu, bese uxhumano lwangaphandle lwenziwa ngokwesimo se-voltage, futhi i-voltage ephezulu ihambelana noxhumano lwenkanyezi kanti i-voltage ephansi ihambelana noxhumano lwe-Angle.
Kungani usebenzisa uxhumano lwenkanyezi kuma-motor ane-voltage ephezulu：
Kumamotha ane-voltage ephansi, azohlukaniswa ngokwamandla, njengochungechunge oluyisisekelo lwamamotha ngokuya ngesigaba se-3kW, kungabi ngaphezu kwe-3kW ngokuya ngesixhumanisi senkanyezi, esinye ngokuya ngesixhumanisi se-Angle, kanyeama-motor emvamisa eguquguqukayo, ngokwesigaba esingu-45kW, hhayi ngaphezu kuka-45kW ngokwesixhumanisi senkanyezi, esinye ngokwesixhumanisi se-Angle; Kuma-motor okuphakamisa kanye ne-metallurgical, kunezinhlanganisela zezinkanyezi eziningi, futhi ama-motor okuphakamisa amakhulu azosebenzisa nezinhlanganisela ze-Angle. I-motor ye-voltage ephezulu ngokuvamile iyimodi yokuxhuma inkanyezi, inhloso iwukugwema ukugoqa kwemoto ukuze imelane ne-voltage ephezulu. Ekuxhumekeni kwenkanyezi, umugqa wamanje ulingana nomugqa wamanje wesigaba, kanti umugqa wamanje uphindwe kathathu kunempande ye-voltage yesigaba (ekuxhumaneni kukanxantathu, umugqa wamanje ulingana nomugqa wamanje wesigaba kanti umugqa wamanje ulingana no√Izikhathi ezi-3 zamandla kagesi esigaba), ngakho-ke i-voltage ethwalwa yi-motor winding iphansi kakhulu. Kuma-motor ane-voltage ephezulu, i-current ivame ukuba yincane, kanti izinga lokufakwa kwe-motor liphakeme, ngakho ukufakwa kwe-insulation ye-motor connection star kuphathwa kangcono futhi kuyonga kakhulu.
