BATTERY POWERED ELECTRIC GUIDED VEHICLE

Zadana naloga zajema preučitev porabe avtomatsko vodenega vozička in pridobitev ostalih informacij, povezanih z njim. Predstavljen je obstoječi voziček, ki je ožičeno napajan. Za pridobitev podatkov glavnega pogona obstoječega vozička so bile izvedene meritve na neobremenjenem in obremenjenem vozičku. Izračunane so sile, ki delujejo na voziček med pospeševanjem, enakomernim gibanjem in pojemanjem vozička. Opravljene so tudi meritve uporabljenega asinhronskega motorja v prostem teku in kratkem stiku za določitev parametrov, ki so uporabljeni v modelu. Prikazano je tudi nadomestno vezje asinhronskega motorja, pripadajoče enačbe in enačbe za dvoosni dinamični model stroja. Na koncu naloge so podane še primerjave rezultatov meritev in rezultatov uporabljenega modela pogona za neobremenjeni in obremenjeni voziček, poraba energije in določitev kapacitete baterije.The thesis deals with examination of use of an automatically guided vehicle and gaining other information concerning the vehicle. The vehicle powered by cables is presented. To get information about the main drive of the vehicle measurements had to be carried out on an unloaded as well as on a loaded vehicle. The forces that have an effect on the vehicle during acceleration, steady movement and deceleration have been calculated. Furthermore, measurements of the used asynchronous motor in no-load test and locked rotor test were used in the model. The thesis also shows a equivalent circuit of the asynchronous motor, corresponding calculations and calculations for two-axis dynamic model of the machine. The final part of the thesis introduces comparisons of the measurement results and the results of the used drive model of a loaded and unloaded vehicle, consumption of energy and determination of battery capacities
