Uma uke waba nethuba lokubamba iqhaza ekuhlolweni kwezinjini, ungase ube nokuqonda okujulile kobuchwepheshe bokuguqula imvamisa. Ikakhulukazi labo abahlangabezane nemishini yokuhlola endala bangazizwa kangcono izinzuzo zobuchwepheshe bokuguqula imvamisa.
Noma ngabe ukuhlolwa kokuhlolwa kwemoto noma uhlobo lokuhlolwa, inqubo yokuqala yemoto izotholwa. Ikakhulukazi esimweni samandla amakhulu e-motor kanye nomthamo wegridi encane, ukuqala kwe-motor no-load kuzoba nzima kakhulu. Inqubo yokuhlola ifana nalokhu, futhi inqubo yokufaka injini ekusebenzeni nayo ingacatshangwa.
Ukuhlolwa kwetafula ukuqinisekisa ukuthi i-motor rotor isesimweni esimile. Kuyisivivinyo sezici zokuqalisa injini nezici zokugcwala ngokweqile. Kumamotho amafrikhwensi ezimboni, ukuqala kuhlale kuyisici esibucayi kakhulu, ikakhulukazi ngezikhathi ezithile ezikhethekile. Ngenxa yezici ezifana nezimo zokusebenza noma izingqinamba zokusebenza kwemishini, kuvame ukuba khona ugesi wemvamisa yezimboni kuphela, futhi vele kuzokhethwa ama-motor frequency embonini.
Izimboni eziningi zezimoto, ikakhulukazi lezo ezisanda kuthenga noma ezithuthukisiwe imishini yokuhlola, nazo zamukele ukunikezwa kwamandla kagesi okuguquguqukayo, okuyixazulule ngokuphelele inkinga yokuqaliswa kwezimoto. Kodwa-ke, kukhona futhi nezinkinga, okungukuthi, ubuthakathaka bokusebenza kwemoto abukwazi ukutholakala ngokugcwele. Kwake kwaba nenqwaba yamamotho anesivinini esikabili angatholanga noma yikuphi okungalungile ngesikhathi sokuhlolwa komkhiqizi, kodwa umsebenzisi wehlulekile ukuqala ngesivinini esithile. Ukuhlolwa okwengeziwe kuveze ukuthi injini ihlolelwe kuphela ukuthi iqala ukusebenza ngesivinini esisodwa, kanti ukusebenza kwemoto kwesinye isivinini akutholakalanga ukuthi ayenele. Kodwa-ke, injini yaqalwa ngesivinini esihambisanayo ngokungasebenzi kahle kokuqala ngesikhathi sokusetshenziswa kwangempela. Eqinisweni, kulula kakhulu ukuqalisa injini ngefrikhwensi eguquguqukayo, yingakho ingaqala ngesikhathi sokuhlolwa kodwa ingase ibe nezinkinga ngaphansi kwezimo zokusebenzisa imvamisa yamandla.
Izinjini ezisebenza kahle kakhulu ziwumkhiqizo wesiqondiso senqubomgomo kazwelonke. Izidingo ezisebenza kahle kakhulu zochungechunge oluyisisekelo lwamamotho ziphoqa abakhiqizi abahlukene ukuthi benze ukuthuthukiswa kwedizayini ngokusebenzisa izindlela zobuchwepheshe, okungase kubandakanye ukutshalwa kwezimali kwezinto ezibonakalayo.
Lapho injini yefrikhwensi yezimboni iqalwa nge-voltage egcwele, ngenxa yemfuneko ye-torque yokuqala ye-motor, i-current current izikhathi ezi-5-7 zamanje ezilinganiselwe, ezimosha ugesi futhi zidale umonakalo omkhulu kugridi yamandla. Uma imvamisa eguquguqukayo iqala yamukelwa, umthelela wamanje wokuqala kugridi yamandla uyancishiswa, izikweletu zikagesi zigcinwa, futhi umthelela we-inertia yokuqala ngesivinini se-inertia enkulu yemishini iyancishiswa, okwandisa impilo yesevisi. kwemishini. Iyazuzisa igridi yamandla, injini kanye nemishini edonsayo. Umthelela wobuchwepheshe befrikhwensi eguquguqukayo ekuqaliseni kwezimoto usobala kakhulu, kodwa futhi kunezici ezithile ezingezinhle ekusetshenzisweni kwamamotho ashintshashintshayo. Isibonelo, amagagasi angewona ama-sinusoidal akhiqizwa yi-inverter anomthelela omkhulu ekuthembekeni kwe-motor futhi ajwayele ukukhiqiza imisinga ye-shaft. Ikakhulukazi kumamotho anamandla amakhulu kanye ne-voltage enezinga eliphezulu, inkinga inkulu kakhulu. Ukuze ugweme inkinga yamanje ye-shaft, ukukhethwa kwezinto zokufaka umoya we-motor kanye nezinyathelo zokuvimbela zamanje ze-shaft kuyadingeka kakhulu.
