Modelování a simulace asynchronního motoru pro napájení z měniče kmitočtu

Abstract

Direction of this thesis was creating mathematical and simulation model of induction motor for supplying from frequency converter. Were created three separate mathematical models of induction motor that take into account the electromagnetic processes. At first was created model of induction motor that doesn’t take into account the main magnetic circuit saturation. This model served as a ground for creation following models of induction motor. Further were created flux and current models that take into account the main magnetic circuit saturation. At last was created mathematical model of frequency converter. In terms of these mathematical models were created six separate simulation models in special software MATLAB - Simulink 5.3. For examination of correct creation mathematical and simulation models were on all simulation models simulated curves of output signals. Important simulated curves of output signals from flux and current models of induction motor were compared each other.
