Abstract

In the article an approach to improvement of the belt conveyor performance at the stage of its srart-up has been developed. It was achieved by developing a mathematical model of the conveyor movement under control from the soft starter (the work takes into account the equation of the dynamics of the movement of the mechanical part of the conveyor and the equations of the asynchronous electric drive, which is supplied by the soft starter). The parameters of the soft starter have been determined, which have the strong impact on the dynamic and energy performance of the conveyor. By carrying out numerical experiments, a data array was obtained that connects the settings of the soft starter (the duration of the supply voltage rise and the initial drive supply voltage) with the values of the estimated dynamic and energy performance of the conveyor. Estimates reflected RMS and maximum values. The analysis made it possible to obtain rational values of the optional parameters of the soft starter, at which the dynamic loads and energy losses significantly decreased.
