The transient rotation of the asynchronous electric motor is studied under external loading generated by a vibration field. The present paper studies the synchronization effect between the angular velocity of the rotor and the frequency of external vibrations, which usually appears in practice under some defined conditions. This leads to the elongation of transient motions, as well as, to some electric energy loss. As a result the lifetime of the engineering structure falls down. Experimental studies of the problem of decreasing the vibration level are focused on using hydraulic dampers tested on the railway locomotive ВЛ-8ОС. Some economical benefits of using such dampers in practice are discussed.
