Analysis of the Results of Mathematical Modeling of the Process of Applying Micropits to the Commutator Surface

The article presents an analysis of the results of mathematical modeling of the process of applying micropits to the surface of an electric motor commutator using abrasive belt grinding. Based on mathematical modeling, a computer model of the process of forming micropits on the commutator surface was developed to enhance its wear resistance. The computer model enabled a numerical analysis of the micropit formation process and its visual representation through graphs. It was shown that as the grit size of the abrasive belt increases, the number of micropits decreases, while the total surface area of the micropits increases. The dependence of the total surface area of micropits and their number on the number of abrasive belt passes was also established.
