20.500.12556/DKUM-18026 ANALIZA RAZLIČNIH NAČINOV ZAVIRANJ ASINHRONSKEGA MOTORJA ANALYSIS OF DIFFERENT WAYS OF BRAKINGS OF ASYNCHRONOUS ENGINE V diplomski nalogi so predstavljeni različni načini zaviranja asinhronskega motorja, primerjave med njimi ter posamezne specifičnosti različnih zaviranj. Izvedli smo generatorsko in protitočno zaviranje ter zaviranje z enosmernim tokom. Pri meritvah smo merili čas, vrtljaje, navor, napetost, tok in moč. Iz moči in časa smo izračunali energijo, ki jo motor črpa iz omrežja. Ob izračunani energiji so v diplomski nalogi predstavljeni in opisani še merjeni vrtljaji in tok. Najprej smo zavirali protitočno in generatorsko, nato pa smo s pomočjo variaka, s katerim smo zagotovili motorju enosmerno napajanje, zavirali z enosmerno napetostjo. Meritve pri zaviranju z izmenično napetostjo smo izvajali pri treh različni momentih bremena. Pri zaviranju z enosmerno napetostjo smo imeli dve različni vezavi in dva nastavljena toka na statorju. In this diploma, we introduce different ways of applying braking methods to an asynchronous engine, comparisons between them and the individual specifications of different braking methods. We carried out tests using generator braking, countercurrent braking and DC braking. For measurements, we measured the time, rotations, torque, voltage, current and power. From the power and time we calculated the energy that draws from the engine system. In addition to calculating the energy, we also introduced and described measured rotations and current. First we applied the countercurrent and regenerative braking methods, then we used variak, with which we provided DC power to the engine for braking it with DC voltage. Measurements of the inhibition of AC voltage were performed at three different torque loads. We had two different weaves and two current configurations when braking with DC. asinhronski motor zaviranje induction motor braking true true false [D.
