Small-sized mobile aggregates in the form of motoblocks with internal combustion engines with the capacity of 1-7 kW domestic and foreign production were widely used to increase the efficiency of production of vegetables in protected ground soils. During the work of mobile units with internal combustion engines in greenhouses and greenhouses, noise and gas pollution increase, which negatively affects not only people but also plants.
More promising for work in protected soil structures are mobile aggregates with traction electric motors, which are called electric motors, as ecologically clean aggregates that do not have the named drawbacks.
The purpose of the research is to substantiate and elaborate the structural and electromechanical scheme of an energy-saving soil cultivation system based on an electrified motor block, to obtain a balance of capacities, and to create a mode of control of the DC motor by successive excitation along the maximum of efficiency in the main sections of its mechanical characteristics. \
The electric power unit receives power with a flexible cable, which is supplied with electricity from the AC network. The gate converter converts the electric energy of an alternating current into the electric power of a direct current necessary for further electromechanical transformation in a traction electric motor.
The structural and electromechanical schemes of the energy-saving soil tillage system based on the electrified motor block are substantiated. The obtained control characteristics provide the control of the DPS at the maximum efficiency and the set value of the load factor. In a relatively large zone, the change in the load factor of the engine efficiency is close to the maximum value with a loading coefficient of 0.7-0.9. This significantly simplifies the practical implementation of the modes of control of the DPS with the use of simple design of the gate transducers in the form of thyristor voltage regulators.
