“…The mathematical expectation of the average wear rate of the brushes vsh is determined using the formula, where, together with the found value of Pv, the constants A, B and C from Table 1 should be substituted [15]. The choice of the latter should be coordinated with the choice of the brand of brushes planned for use.…”

The paper presents a new approach to the selection of characteristic points on the current-voltage curve (CVC) of the brush contact of traction electric machines, for their approximation in the form of three different functions, with characteristic points of transition to the field weakening mode. The problem of raising resources by using new design electro brushes. This constructive solution is consistent with the specific types of traction motors used in urban and rail transport and satisfies the technical conditions for their operation. A construction brush holders, which will save the cost of electro, in connection with their wear and tear due to friction on the walls of the brush holders. Improving the quality of machines saves material means and human resources, increase the profitability of their use, resulting in a significant increase in productivity. The method of calculating the current-voltage characteristics of a new type electro brushes, the distinguishing feature of which is the introduction of a cross section of the body brush. In the course of the experiment revealed steadily increasing rate of proposed electro brushes, compared with the standard of the same type EG61A. Data collected during the experiment showed that electro brushes with a transverse incision is more stable contact with the collector.
