Abstract
In the article, for a specific example, the model of the asynchronous motor with short-circuited rotor in the MATHCAD software environment is considered. In compiling the model, displacement of the current in the rotor (skin effect) is taken into account by representing the rotor with two short -circuited cells. For simulation a complete system of differential equations is used, written for stator circuits, rotor and for the rotor motion equation. The simulation results are graphical relationships that reflect the change in the basic parameters of the asynchronous motor, which, in turn, allow them to be analyzed over time. The obtained data give the opportunity to continue the work on modeling machines of asynchronous type from the point of view of diagnostics and analysis in case of changes in individual values that directly or indirectly influence their operation.
