“…The introduction of a Brushless DC Motor (BLDC) [9,10] allowed to increase the traction efficiency of the tractor by an average of 3% in agricultural work. According to [11], the permanent magnet synchronous motor (PMSM) is the best choice for use in the electric drive system of a tractor, because due to proper torque control, it meets the standards of an agricultural tractor [12,13].…”

One of the promising steps to improve the environment in various industrial sectors is the transfer of specialized technical means to alternative clean energy. Agriculture is not an exception, because the introduction of an electric drive on tractors of small traction classes, which are designed to perform traction, as well as small transport work, is relevant today. Such an implementation is implemented by replacing the internal combustion engine with an electric drive, in connection with this; the task of observing the traction properties of the tractor arises. Therefore, the material of this type aims to increase the traction efficiency of the wheeled lowpower tractor by optimizing its design features. The implementation of the outlined goal occurs due to the use of multi-criteria optimization when conducting a simulated numerical experiment of traction test cycles. When solving the set goal, the method of dynamic tests of the German Agricultural Society DLG-PowerMix is used, this includes 12 traction tests of an agricultural tractor. The result is a justified selection of the distribution of the total weight of the low-power tractor in combination with the tire pressure in conditions of compliance with the maximum average integral values of the speed and efficiency of the tractor, as well as the minimum average integral value of skidding, as those that should be implemented in an electric tractor. The practical significance of the work consists in providing specific values of weight distribution on the axle of the low-power tractor and tire pressure when aggregating with a plow, a cultivator, a rotary cutter and a hay mower, as well as taking into account the operation of a manure spreader and a hay baling. The scientific novelty of the work is the establishment of a relationship between the design parameters of the low-power tractor and the change in traction indicators during traction work, namely between the tractor weight distribution, tire pressure, speed, tractor efficiency and wheel slip.

In recent years, studies aiming to use different motor types for traction purpose, such as in electric vehicles, have become increasingly widespread. Among these motor types, permanent magnet assisted synchronous reluctance motor (PMa-SynRM) has become in-creasingly preferred in commercially electric vehicles nowadays. This study addresses the design and control of a PMa-SynRM, also the comparison with the synchronous reluc-tance motor (SynRM). The motor design process is carried out using the finite element method in Ansys-Maxwell environment. A series of a simulation studies is conducted in the MATLAB/Simulink environment for controlling the obtained motor designed in An-sys-Maxwell. The field-oriented control (FOC) approach is chosen for precise speed con-trol. As a result of the simulation studies, it is observed that the designed motor tracks the reference with minimal error under various load conditions within a closed-loop system. Also, this paper investigates how the PM implementation affects the machine perfor-mance comparing to SynRMs. In addition, such a study takes into account that the de-sign of machines involves always several constraints, including geometry, materials, sup-ply limits, and performance constraints.
