Umphakeli weyunithi yempendulo ye-frequency converter ukukhumbuza ukuthi indlela yokumisa injini ngokushesha ngokuyinika itorque kagesi ephambana nendawo yangempela yokuzungezisa ngenkathi unqamula ukunikezwa kwamandla. Izindlela ezisetshenziswa kakhulu ukubhuleka ukusetshenziswa kwamandla kanye nokuhlehla amabhuleki.
1. Ukubhuleka ukusetshenziswa kwamandla
Indlela yokukhiqiza inkambu kazibuthe emile ngokunqamula ukunikezwa kwamandla kagesi e-AC enjinini futhi inikeze noma iyiphi isamba samandla e-DC ku-stator winding, kuncike ekujikelezeni kwe-rotor ukuze kusike futhi kulungiswe indawo kazibuthe emile futhi kukhiqize i-torque yokubhuleka.
2. Ukuhlehla ukubhuleka
Indlela yokuguqula ukulandelana kwesigaba samandla se-stator winding yenjini ngenkathi inqamula ukunikezwa kwamandla okusebenza okuvamile, ukuze ibe nokuthambekela kokuhlehla futhi ikhiqize i-torque enkulu yokubhuleka. Ingqikithi ye-reverse braking ukwenza injini ifune ukuhlehla futhi ibhuleke. Ngakho-ke, lapho isivinini se-motor sisondela ku-zero, ukunikezwa kwamandla okubuyela emuva kufanele kunqanyulwe, ngaphandle kwalokho injini izohlehla. Ekulawuleni okungokoqobo, i-relay yesivinini isetshenziselwa ukunqamula ngokuzenzakalelayo ukunikezwa kwamandla okubhuleka.
3. Ukubhuleka impendulo yokukhiqiza amandla
Lapho ijubane lemoto kagesi lidlula ijubane lensimu kazibuthe ezungezayo, isiqondiso se-torque kagesi iphambene nokuqondisa kokunyakaza kwe-rotor, ngaleyo ndlela ikhawulela isivinini se-rotor futhi idlala indima yokubhuleka. Ngoba lapho ijubane le-rotor likhulu kunejubane lokujikeleza lensimu yamagnetic ejikelezayo, amandla kagesi abuyiselwa kusuka ku-stator ye-motor kuya emthonjeni wamandla, futhi empeleni, injini isivele ishintshele ekusebenzeni kwe-generator. Ngakho-ke, lolu hlobo lokubhuleka lubizwa ngokuthi i-power generation feedback braking.
