Ukwenzela iinjini enamanqanaba amathathu, i-stator winding ineentlobo ezimbini zonxibelelwano, unxantathu kunye neenkwenkwezi, unxibelelwano lweenkwenkwezi kukudibanisa umsila we-three-phase winding kunye, kwaye intloko ye-three-phase winding iqhagamshelwe nombane; Indlela yonxibelelwano lweenkwenkwezi ineemeko ezimbini zonxibelelwano lwangaphandle kunye nonxibelelwano lwangaphakathi, i-internal star connection motor yi-star point eqhagamshelwe ne-three-phase winding imiselwe kwindawo efanelekileyo ye-stator winding, kukho iziphelo ezintathu zokuphuma eziphumayo, kwaye unxibelelwano lwangaphandle luyintloko kunye nomsila we-three-phase winding zonke zikhokelwa ngaphandle, kwaye unxibelelwano lwangaphandle kunye neentambo zemoto.
Indlela yoqhagamshelo olunxantathu kukudibanisa intloko ye-phase winding nomsila we-phase winding enye, oko kukuthi, i-U1 kunye ne-W2, i-V1 kunye ne-U2, i-W1 kunye ne-V2, kwaye indawo yoqhagamshelo iqhagamshelwe kumbane.
Ukuba ukujija kwesigaba ngasinye kuthathwa njengomgca, emva kokuba iinkwenkwezi ziqhagamshelwe, kufana nenkwenkwezi ekhazimlayo, kwaye umthetho woqhagamshelo lwenxantathu ufana nonxantathu, ngoko ke kubizwa ngokuba luqhagamshelo lweenkwenkwezi okanye uqhagamshelo lwenxantathu. Singadibanisa nemoto enxantathu kwiimeko ezimbini ze-Angle yangaphakathi kunye ne-Angle yangaphandle.
Ukuba yimoto ene-voltage enye, zombini ngaphakathi nangaphandle zinokudityaniswa, kodwa kwimoto ene-voltage ezimbini, kuphela intloko nomsila we-winding yesigaba sesithathu onokutsalwa, uze emva koko uqhagamshelo lwangaphandle lwenziwe ngokwemeko ye-voltage, kwaye i-voltage ephezulu ihambelana noqhagamshelo lweenkwenkwezi kwaye i-voltage ephantsi ihambelana noqhagamshelo lwe-Angle.
Kutheni usebenzisa uqhagamshelo lweenkwenkwezi kwiimoto ezine-voltage ephezulu：
Kwiimoto ezine-voltage ephantsi, ziya kwahlulwa ngokwamandla, njengoluhlu olusisiseko lweemoto ngokwesahlulo se-3kW, kungabi ngaphezu kwe-3kW ngokwesahlulo seenkwenkwezi, enye ngokwesahlulo se-Angle, kwayeiimoto zefrequency eziguquguqukayo, ngokwe-45kW division, kungabi ngaphezu kwe-45kW ngokwe-star connection, enye ngokwe-Angle connection; Kwii-lifting kunye nee-metallurgical motors, kukho ii-star joints ezingaphezulu, kwaye ii-lifting motors ezinkulu nazo ziya kusebenzisa ii-Angle joints. I-high voltage motor ngokubanzi yindlela yokudibanisa inkwenkwezi, injongo kukuphepha i-motor winding ukuze imelane ne-voltage ephezulu. Kwi-star connection, i-line current ilingana ne-phase current, kwaye i-line voltage iphindwe kathathu ingcambu ye-phase voltage (kwi-triangle connection, i-line voltage ilingana ne-phase voltage kwaye i-line current ilingana ne-√I-phase current iphindwe kathathu), ngoko ke i-voltage ethwalwa yi-motor winding iphantsi kakhulu. Kwii-motor ezine-voltage ephezulu, i-current idla ngokuba ncinci, kwaye inqanaba le-insulation ye-motor liphezulu, ngoko ke i-insulation ye-star connection motor iphathwa ngcono kwaye ingabizi kakhulu.
