Umshini uphahlazekile ngemuva kokusebenza isikhashana.Siyini isizathu?Ingabe isiguquli semvamisa sinekhodi enephutha?Uma kunjalo, hlola imanuwali.Iningi lazo lisebenza ngokweqile futhi lingaphansi kwamandla.Uma kuvamile, ukungqubuzana kwemishini ye-inverter epholile emoyeni kungase kube kukhulu futhi ukumelana kuzoba kukhulu.Lungisa inani lamanje kancane kakhulu noma i-torque kakhudlwana.Ungalungisi kakhulu ngesikhathi esisodwa, kuye ngokuthi i-current rated of the motor.Hlola ukuthi izisetshenziswa zamandla aphezulu ziyaqala yini uma isiguquli sefrikhwensi sima, okuholela ekungabini kwamandla kagesi.
Isixazululo kanye nokuhlaziywa kwembangela:
Okokuqala, isikhathi sokunciphisa isiguquli sefrikhwensi sisethwe sibe sifushane kakhulu.Uma isiguquli sefrikhwensi sidonsa umthwalo omkhulu, isikhathi saso sokunciphisa sisethwa sincane kakhulu.Ngesikhathi senqubo yokunciphisa, imvamisa yokuphuma kwesiguquli sefrequency yehla ngokushesha kakhulu, kuyilapho inertia yomthwalo inkulu, okwenza isivinini sangempela semoto sibe phezulu kunejubane elihambisana nemvamisa yokuphuma kwesiguquli sefrequency, okwenza injini ibe semoyeni. isimo sokukhiqiza amandla, ngaleyo ndlela kubangele ukuthi i-voltage yesixhumanisi se-DC maphakathi nesiguquli sefrikhwensi ibe phezulu kakhulu, ifinyelele inani elilinganiselwe kanye nokukhubeka, Ngakho-ke, iziguquli ezinkulu zefrikhwensi ngokuvamile zifakwe amayunithi okucubungula amagama angaphezu kwe-overvoltage.
Okwesibili, lapho ama-motor amaningi eshayela umthwalo ofanayo, ngenxa yokuthi akukho ukusatshalaliswa komthwalo, lapho isivinini sangempela semoto eyodwa sidlula isivinini sesikhathi senye imoto, ijubane elikhulu lilingana nomhambisi oyinhloko, futhi ijubane eliphansi lilingana generator, okungase futhi kubangele iphutha over-voltage.
Okwesithathu, ngenxa yempilo ye-capacitor yesixhumanisi se-DC esiphakathi kwesiguquli se-frequency, ngemva kweminyaka yokusetshenziswa, umthamo we-capacitor uyancipha, nekhono lokulungiswa kwesixhumanisi esimaphakathi se-DC ku-voltage ye-DC liyehla, kanye namathuba okukhubeka ngokweqile.Ekusetshenzisweni okungokoqobo, isici sesibili singaphezulu.Thatha isiguquli se-ladle trolley yesithando somlilo se-rh njengesibonelo.Ishayelwa izinjini ezimbili ezinomthwalo ofanayo.Ukwehluleka kwe-alamu ye-overvoltage kuvame ukwenzeka ngesikhathi sokusebenza, futhi isiguquli esifanayo sivame ukukhala.Ngokubheka, inani le-voltage yesixhumanisi esimaphakathi se-DC sesiguquli liphezulu kumafrikhwensi aphezulu ngesikhathi sokusebenza.Ngokuhlaziya, ijubane langempela lemoto eyodwa liphakeme kunejubane langempela lenye injini, okwenza ukuthi isebenze esimweni sokuphehla amandla, Futhi isixhumanisi esimaphakathi se-DC sisebenzisa le ngxenye yamandla kahle kakhulu, okuholela ku-voltage ngokweqile isixhumanisi se-DC esiphakathi kwesiguquli sefrikhwensi, kanye nephutha le-over-voltage liyabikwa.
