The tests were carried out according to IEEE Std 112 and IEC 60034-2-1. The parameters of the equivalent circuit were identified and entered into the model. Validation was performed by comparing the torque–speed and current–speed curves at 180 V and 220 V, while the nominal behaviour at 400 V was estimated using the model and voltage scaling. The model was then calibrated to reduce the discrepancy between the simulation and measurements, and the error was quantified using the root-mean-square error (RMSE) and mean absolute percentage error (MAPE). An automated load-simulation setup that reproduces the torque test is also presented, enabling rapid evaluation of parameter influence. The results show a very good match in the current channel, with larger deviations in the prediction of characteristic torque points, indicating the limitations of linearised parameters and motivating nonlinear model extensions. The approach enables summarised reliable estimates at nominal voltage when direct measurements are not feasibleČlanek predstavlja metodološki okvir za gradnjo digitalnega dvojčka asinhronskega motorja na podlagi standardiziranih preskusov in dvoosnega (dq) simulacijskega modela. Preskusi so bili izvedeni v skladu s standardoma IEEE Std 112 in IEC 60034-2-1. Parametri ekvivalentnega vezja so bili določeni in vneseni v model. Validacija je bila izvedena s primerjavo krivulj navor–hitrost in tok–hitrost pri 180 V in 220 V, medtem ko je bilo nazivno obnašanje pri 400 V ocenjen? z uporabo modela in skaliranja napetosti. Model je bil nato umerjen za zmanjšanje razlike med simulacijo in meritvami, napaka pa je bila kvantificirana z uporabo srednje kvadratne napake (RMSE) in povprečne absolutne odstotne napake (MAPE). Predstavljena je tudi avtomatizirana merilna postavitev za simulacijo obremenitve, ki ponazarja preskus navora in omogoča hitro oceno vpliva parametrov. Rezultati kažejo zelo dobro ujemanje v kanalu toka, pri napovedi značilnih točk navora pa so večja odstopanja, kar nakazuje omejitve lineariziranih parametrov in spodbuja razširitve modela na nelinearne. Pristop omogoča zanesljive povzetke ocen pri nazivni napetosti, kadar neposredne meritve niso izvedljiveTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
