In the article is presented a method of modeling processes in a run down regime of an induction motor with a squirrel-cage rotor with broken bars. This method based on the mathematical model of induction motor with a squirrel-cage rotor. Differential equations of this model are composed of mesh current method for line-to-line voltages. This method allows to calculate the harmonic spectrum of current distribution in rotor bars, the rotor speed, the damping coefficient of the currents in the run down regime and the electromotive difference of potential induced in the stator windings, with an accuracy of 10-15%. Results of calculation and experiment are presented in the article.

W artykule opisano modelowanie silnika indukcyjnego z uszkodzonym wirnikiem na etapie zwalniania ruchu. Metoda pozwla obliczać widmo prądu w prętach wirnika, prędkośc wirnika, wspólczynnik tłumienia prądu oraz potencjał indukowany w uzwojeniu stojana. Wyniki obliczrń porównano z danymi eksperymentalnymi.
