Improvement the calculation methods of the electromechanical drive taking into account variability of loading

In paper the problem of the description of non-stationary processes of separate class of electromechanical systems on the example of seine raising complex is considered. As a result of researches the problem of improvement the methods of calculation of the electromechanical drive taking into account variability of loading has been solved. The received analytical dependences for determination of tension force of purse line can be used at a design stage of EMD of fishing winches. Also the results of research stated in this work at a design stage can provide increase of operational reliability and overall performance of system of the drive on the basis of the choice of rational parameters of operation.
