Abstract

Improving the reliability of trolley traction motors can be achieved by further improving the traction motor design and their control parameters in the manufacture, repair and operation on the line. Technical diagnostics of traction motor parameters plays an important role in solving these problems.

Known diagnostics methods of traction motors allow to detect their faults. But there is a need to improve these methods, taking into account the capabilities of modern measuring systems and information processing tools. This will allow to improve the performance indicators of urban electric transport enterprises due to improving the operational reliability of traction motors and extending their service life. The relevance of this problem is also caused by the tendency to increase the probability of correct and accurate diagnosis at various faults in electric machines.

The operational reliability of trolley motors was comprehensively analyzed, and regularities of their parameters change during operation depending on several factors were determined in this paper. Mathematical modeling of traction motors to determine their parameters change during operation was conducted. An algorithm for diagnosing and determining the operational reliability of trolley traction motor elements using the boundary criteria was developed and the reliability calculation methods, allowing to predict failures of traction motor elements with a high adequacy degree were proposed. Practical recommendations for the rational selection of diagnostic parameters of traction motors were given.
