Umsebenzisi womnatha ucebise ukuba ingcaciso ethelekisekayo nohlalutyoyenqanaba lesithathu lemoto yenqanaba elinye kufuneka liqhutywe.Ukuphendula lo mbuzo womnatha, sithelekisa kwaye sicazulule ezi zimbini kule miba ilandelayo.
Njengoko igama libonisa, kukho ucingo lwesigaba esisodwa kuphela sombane wesigaba esisodwa, kwaye ucingo lwayo luqulunqwe ngocingo oluphilayo kunye nocingo olungathathi hlangothi; Umbane wamanqanaba amathathu unezigaba ezintathu, kwaye iingcingo zawo zinezigaba ezithathu zocingo, oko kukuthi, iingcingo ezintathu eziphilayo kunye nolunye ucingo olungathathi hlangothi.Unokuguqula ucingo oluphilayo kunye nocingo olungathathi hlangothi ukusuka kumgca wesigaba sesithathu ukuya kumbane wesigaba esisodwa.Kumgca wonikezelo lwamandla, onke amanqanaba amathathu ombane angena kwindawo yamandla, kwaye emva koko aguqulwa abe yinqanaba elinye okanye inqanaba lesithathu lonikezelo lwamandla ngokuhambelana nobudlelwane bokulinganisa umthwalo kunye nokusetyenziswa okuthe ngqo.
I-stator winding yesigaba sesithathu se-AC induction motor iqulethwe ngamanqanaba amathathu e-windings apho izigaba ezithathu zihluke ngamadigri ombane angama-120 kwindawo ebonakalayo. Isenzeko somzimba apho ukwakheka kwemigca yamagnetic yokusika phakathi kwemicu kusebenza.Xa i-stator-stator winding ye-motor idityaniswe kwinqanaba lesithathu le-symmetrical alternating current, i-magnetic field ejikelezayo iya kuveliswa, kwaye i-magnetic field iya kunqumla i-rotor winding.Ke ngoko, i-current induced current iveliswa kwi-rotor winding yendlela evaliweyo, kwaye umqhubi we-rotor ophetheyo ngoku uya kuvelisa amandla ombane we-electromagnetic phantsi kwesenzo sombane ojikelezayo we-stator, ngaloo ndlela ubumba i-torque ye-electromagnetic kwi-motor shaft. ukuqhuba i-motor ukujikeleza, kunye nesalathiso sokujikeleza kwemoto kunye necala lendawo yamagnetic ejikelezayo. efanayo.
Kwiimotor zesigaba esinye, i-stator winding ngokuqhelekileyo iqulunqwe yinto ehamba phambili kunye ne-second winding. Ngokwahlulahlulo lwamacandelo ahlukeneyo, imisebenzi yee-windings zesibini ayifani.Sithatha i-capacitor-started single-phase motor njengomzekelo we-AC.Ukwenza i-motor-phase-single-motor ijikeleze ngokuzenzekelayo, singongeza isiqalo sokuqalisa kwi-stator. Ukuqala ukujija ngamaqondo angama-90 ahlukileyo ukusuka kwindawo ephambili yokujija. Umahluko wesigaba malunga ne-90 degrees, into ebizwa ngokuba yi-phase-splitting okanye i-phase-shifting principle.Ngale ndlela, imisinga emibini enomahluko we-90 degrees ngexesha idlula kwi-windings ezimbini ezinomahluko we-90 degrees kwindawo, eya kuvelisa (izigaba ezibini) intsimi yamagnetic ejikelezayo kwindawo. Ngaphantsi kwesenzo sale ntsimi yamagnetic ejikelezayo, i-rotor ingaqala ngokuzenzekelayo. Emva kokuqala, xa isantya sifikelela kwinqanaba elithile, ukuvuthwa kokuqala kunqanyuliwe ngokutshintsha kwe-centrifugal okanye esinye isixhobo sokulawula ngokuzenzekelayo esifakwe kwi-rotor, kwaye kuphela umbane oyintloko usebenza ngexesha lokusebenza okuqhelekileyo.Ngoko ke, ukuqala ukujika kungenziwa kwimodi yokusebenza kwexesha elifutshane.
Ngokujonga imida yonikezelo lwamandla kwiindawo ezahlukeneyo, iinjini zenqanaba elinye zisetyenziswa kakhulu kwiindawo zokuhlala, ngelixa iinjini zenqanaba lesithathu zisetyenziswa kakhulu kwiindawo zoshishino.
