Abstract <p>The article provides information about the operating gearmotors and their modifications depending on the gearbox configuration. An analysis of existing information in this area has been carried out, and the advantages and disadvantages of the parts layout in three design (structural) versions have been revealed. Based on the analysis and theoretical justification, an improved model of the gearmotor is proposed. The changes made in the design of the transmission system are described, and a comparative analysis of the technical parameters of the samples is performed. The results of the constructive solutions given by the authors are summed up, and the positive effect of the practical application of these solutions is summarized.</p>
