The algorithm of forecasting of resource of electric brushes traction motors

In this article the generalized results of researches of change of intensity of wear of electrical brushes in the traction motors of electric locomotives. On the basis of the conducted research the author proposes an algorithm to predict the operating life of the brushes, given the parameters of the operation. In order to increase the reliability of the calculation has been developed algorithms, which allow additionally taking into account the effect of the collector’s surface.
