Analitycal dependencies providing inductances calculations of squirrel-cage motor mathematical model including rotor eccentricity (static and dynamic) are presented in the paper. Equations shown in the paper are used for numerical modelling of motor drives with rotor damages. Considerations are supported by simulation test results of an induction motor fed by voltage inverter, controlled by Direct Torque Control method.

PL

W pracy przedstawiono analityczne zależności umożliwiające obliczenia macierzy indukcyjności modelu matematycznego silnika klatkowego z uwzględnieniem uszkodzeń w postaci mimośrodowego osadzenia wału wirnika (mimośród statyczny i dynamiczny). Wyprowadzone zależności wykorzystano do numerycznego modelowania układów napędowych z uwzględnieniem uszkodzeń wirnika. Rozważania poparto wynikami badań symulacyjnych silnika zasilanego z sieci napięciem sinusoidalnym oraz falownika napięcia sterowanego metodą DTC.
