Umhlinzeki weyunithi yokubhuleka uyakukhumbuza ukuthi ukubhuleka okuvuselelayo kwesiguquli sefrikhwensi kubhekise ngakuye isivinini sokuzungeza esiphambene nendawo yetorque yemoto. Isibonelo, ngesikhathi sokunciphisa, lapho isivinini se-rotor singaphezu kwejubane lokuvumelanisa ngenxa ye-inertia yomthwalo, i-motor isesimweni sokuvuselela kabusha. Ukuguqula amandla emishini abe amandla kagesi, isimo sokubhuleka esivuselelwayo samandla kagesi asetshenzisiwe kufanele siguqulwe noma silahlwe.
Uhlobo lokusetshenziswa kwamandla:
Le ndlela ihlanganisa ukuhambisana ne-resistor yokubhuleka kusekethe ye-DC yesiguquli sefrikhwensi, nokulawula ukuvala/ukuvala kwe-transistor yamandla ngokuthola i-voltage yebhasi ye-DC. Lapho i-voltage yebhasi ye-DC ikhuphuka ifinyelele cishe ku-700V, i-transistor yamandla iyaqhuba, idlulise amandla avuselelwe kusiphikisa futhi iwadle ngendlela yamandla ashisayo, ngaleyo ndlela ivimbele ukunyuka kwe-DC voltage.
Ngenxa yokungakwazi ukusebenzisa amandla avuselelwe, ayingxenye yokusetshenziswa kwamandla. Njengohlobo oludla amandla, umehluko wayo ku-DC braking ukuthi idla amandla ku-resistor yokubhuleka ngaphandle kwemoto, ukuze injini ingashisi ngokweqile futhi ingasebenza kaningi.
Uhlobo lokumuncwa kwebhasi le-DC elihambisanayo:
Ifanele izinhlelo eziningi zokushayela izithuthuthu (ezifana nemishini yokwelula), lapho injini ngayinye idinga isiguquli semvamisa, iziguquli zamafrikhwensi amaningi zabelana ngesiguquli eseceleni segridi, futhi wonke ama-inverter axhunywe ngokuhambisana nebhasi elivamile le-DC.
Kulolu hlelo, kuvame ukuba nenjini eyodwa noma eziningana ezisebenza ngokujwayelekile esimweni sokubhuleka. Injini esesimweni sokubhuleka ihudulwa ngamanye amamotho ukuze ikhiqize amandla okuvuselela, abese emuncwa injini esesimweni sikagesi ngebhasi le-DC elihambisanayo. Uma ingakwazi ukumuncwa ngokugcwele, izosetshenziswa nge-resistor yokubhuleka okwabelwana ngayo. Amandla akhiqizwe kabusha lapha amunca kancane futhi asetshenziswa, kodwa awabuyiselwa kugridi yamandla.
Uhlobo lwempendulo yamandla:
Isiguquli eseceleni segridi yohlobo lwempendulo yamandla siyabuyiseleka emuva. Uma amandla okuvuselela ekhiqizwa, isiguquli esibuyiseleka emuva sibuyisela amandla okuvuselela kugridi, okuvumela amandla okuvuselela ukuthi asetshenziswe ngokugcwele. Kodwa le ndlela idinga ukuzinza okuphezulu kokunikezwa kwamandla, futhi uma sekuvele ukuphela kukagesi kungazelelwe, ukuguqulwa nokugumbuqelwa kuzokwenzeka.
