Abstract

Under conditions of rolling production the actual problem is the problem of insuring trouble-free service for all equipment, particularly direct current motors. That is why this article presents the diagnostics methods of direct current motors, which do not require removing the motor from exploitation: vibrational, by the consumption current of the motor, thermal-imaging; the disadvantages of these motors were marked, and another method was offered, based on the analysis of commutations in commutator and partial discharges in the motor windings. This method allows to increase the accuracy and the objectivity of the control of the commutation status during exploitation of the electrical machines. Rolling production characterized by the availability of the groups of similar motors, which are being working in the same mode, at that, the load variation is the same for all of the motors. That is why potential method of diagnosis is based on the analysis of the signal ratios of the parameters of the same type (vibration, currents, high-frequency radiation).
