Information mathematical model of diagnosing of the operational mode of the tractive electromotor on the basis of the analysis of ranges of amplitude-modulated current of the stator caused by failure of its elements and nodes is made. Parameters of the optimum filter are determined by criterion of a maximum of the relation signal/noise of current of the stator on which it is possible to identify technical condition of an object. It is shown that diagnostics, processing and the analysis of results of technical condition of the tractive electromotor on the basis of the analysis of spectral components of current of the stator allow on set of the measured parameters will increase reliability of the made technical solution about maintenance of operational reliability and to study evolution of technical condition and also to reduce probability of an unreasonable output from maintenance.
