“…Сучасне сільськогосподарське виробництво в Україні та за кордоном характеризується масовим застосуванням мобільних енергетичних засобів малої механізації у вигляді малогабаритних мотоблоків (МБ), міні-тракторів та різноманітних спеціалізованих агрегатів в основному з двигунами внутрішнього згорання [1]. В той же час проведені порівняльні випробування виявили, що електрифіковані мотоблоки з тяговими електродвигунами постійного та змінного струму мають ряд переваг в порівнянні з мотоблоком з двигуном внутрішнього згорання, наприклад, легкість керування, простота пуску та зупинки, надійність та економічність у роботі, відсутність загазованості навколишнього середовища [2][3][4][5].…”

In Ukraine, the number of farms, private land users and protected soil structures has increased significantly in recent years. To increase the efficiency of vegetable production, small-sized mobile units in the form of motoblocks with internal combustion engines of domestic and foreign production have been widely used. However, during the operation of mobile units with internal combustion engines in greenhouses and hotbeds, the noise level and air pollution increase, which negatively affect not only people but also plants. The disadvantages of motoblocks with internal combustion engines should also include a fairly high specific consumption of liquid fuel, which has a high cost, difficulties in starting and stopping the unit, as well as the relatively low reliability of the internal combustion engine. More promising for work in protected soil structures are mobile units with traction motors, called electric motors, as environmentally friendly units that do not have these shortcomings. The main technical characteristics of the experimental sample of a small-sized electrified soil-cultivating motoblock are given in the work. The structural scheme of the power energy channel of the electric motor unit is substantiated, which clearly demonstrates the processes of energy conversion in it. The equation of energy balance of the electric motor unit and the main energy ratios that determine the properties of the traction motor in the drive of the electric motor unit are obtained. The algorithm of optimal control of a direct current traction motor by the maximum efficiency for direct current motors of serial and mixed excitation is substantiated. The results of field tests of the prototype of the electric motor unit are presented. The analysis of the obtained results of experimental researches of the electrified tillage motor-drive driven by the direct current motor of sequential excitation testifies to the reduction of specific energy consumption for the main types of tillage by 12-15%.
