Iphuzu eliyinhloko lokuqala: Namathela esimisweni sokuthiisilinganiso se-U/f esingaguqukiNgaphansi kwesivinini sesisekelo, ukugeleza kukazibuthe esikhaleni somoya semoto kuhambelana ngqo ne-i-voltage ye-stator kanye nemvamisa. Ukuqina kwesilinganiso se-voltage-frequency (U/f) kunquma ngqo ukuthi i-magnetic flux ihlala njalo. Ekulawuleni, i-voltage kanye ne-frequency kudingeka kulungiswe ngesikhathi esisodwa ukuze kugcinwe ngokuqinile isilinganiso se-U/f singashintshi, kugwenywe ukukhukhuleka kwe-torque okubangelwa ukugcwala kwe-magnetic flux noma ukungasebenzi kahle. Ngaphezu kwalokho, kuma-motor asynchronous, kuyadingeka ukukhokhela ukwehla kwe-stator voltage ukuze kulwiswane nomthelela wokwehla kwe-voltage ebangeni lejubane eliphansi ekuqondeni kwe-torque futhi kuthuthukiswe ukuthembeka kokusebenza kwejubane eliphansi.
Iphuzu Eliyinhloko Lesibili: Ukulawulwa Okunembile Kwezingxenye Zamanje. Ngokusebenzisa ukwakheka kokulawula i-vector, imisinga yesigaba esithathu ye-stator iguqulwa ibe izingxenye zesistimu ye-dq coordinate. Umsinga we-q-axis uhambelana ngqo ne-ukuphuma kwe-torquefuthi kudingeka kuqiniswe ngenani elibekiwe ngokusebenzisaukulawula okuvaliwe. Umsinga we-d-axis ugcina ukuvusa okuqhubekayo ukuqinisekisa ukuzinza kokuhamba kwamandla kazibuthe. Ngesikhathi esifanayo, imikhawulo yamanje esethiwe isethwe ukuze ibhekane nokushintsha komthwalo okungazelelwe kanye nezimo zokuqala, igweme ukushiswa kwamadivayisi kagesi ngenxa yamandla okushaya kanye nokuqinisekisa ukuphuma kwe-torque okubushelelezi nokungathuki.
Iphuzu Lesithathu Eliyinhloko: Isinxephezelo Sokuphazamiseka Okusebenzayo kanye Nokuzivumelanisa Nezimo Zokusebenza. Ukuqapha kwangempela kwamapharamitha afana nesivinini, umthwalo, kanye nokushisa kwenziwa. Lapho umthwalo ushintsha ngokuzumayo, izilinganiso ze-voltage kanye nezamanje zilungiswa ngokushesha ukuze kulungiswe umthelela wokuphazamiseka ku-torque. Ukuze kube nokukhukhuleka kwamapharamitha okubangelwa ukwanda kwezinga lokushisa, kuhlinzekwa indlela yokulinganisa enamandla ukulungisa ukuphambuka ekumelaneni nasekungeneni. I-logic yokuqalisa ilungiselelwe, futhi kusetshenziswa indlela yokuqalisa ethambile ukuze kuncishiswe ukushaqeka kwe-torque, kufezwe ukuqalisa okubushelelezi ezimweni zemithwalo esindayo futhi kuqinisekiswe ngokuphelele ukunemba nokuzinza kokulawulwa kwe-torque okuqhubekayo.
