The optimal mode of operation of an electric car depends to some extent on the technical condition of its mechanical parts. Under operating conditions, unbalanced masses, eccentrically located in relation to the axis of rotation, may occur in the rotor of an electric car, which, in turn, will lead to premature output of machine bearings and, as a consequence, to a deterioration in dynamic characteristics. In this regard, the paper presents a method of compensating for the impact of unbalanced masses of the rotor, during which the analysis of the relationship between the amplitude of the oscillation and the angle of attachment of the compensating load is performed according to the measurement results. One of the downsides of this method is the multiple launches of the electric car and the use of concepts such as balancing sensitivity, corrective mass and more. A relatively flexible method of dynamic balancing of an electric car is shown, based on the measurement of the vibration speed amplitude and vibration phase of the electric car. Relevant oscillograms and analytical images are given, the analysis of which achieves complete suppression of electric vehicle vibration by attaching additional compensating load to the rotor.
