An analysis of the drive characteristics of technological machines and mechanisms of agricultural production showed that their working bodies in 56.3% of cases have rotational motion, and in 43.7% they have translational motion. Special electromechanical and electromagnetic converters - an electric drive with a linear asynchronous motor - are very promising for driving the working bodies of technological equipment that perform translational and oscillatory motion, as well as rotational motion with a rotation speed of up to 500 min−1. A linear asynchronous electric drive makes it possible to implement technologically specified drive characteristics, integrate the power parts of an electric motor with a working body with the exception of mechanical converters, while reducing material and energy consumption, increasing operational reliability of process equipment as a whole. The choice of the optimal winding scheme and the design of the magnetic circuit of the inductor, the material of the secondary element increases the energy and traction performance of the linear induction motor. The study and modeling of electromagnetic processes and the optimization of geometric dimensions, winding data of the inductor and electrical parameters can be effectively carried out on a mathematical model of a linear induction motor by a numerical method, represented by a system of three matrix equations describing the states of the magnetic and electrical circuits of the machine, detailed to the level of tooth division and winding section.

Since induction motors were invented, human civilization has changed forever. Due to their beneficial characteristics, induction motors are widely used and have become the most prevalent electrical counterparts. Many control strategies for induction motors have been developed, varying from scalar to vector control. In the class of vector control, the Direct Torque Control (DTC) was proposed as an alternative that ensures separated flux and torque control while remaining completely in a stationary reference frame. It offers direct inverter switching, reasonable simplicity than other vector control techniques, and less sensitivity to parameter variation. However, the use of hysteresis controllers in conventional DTC involves non-desired ripples in the system's flux and torque, which leads to bad system performances, primarily in low-speed operations. This paper aims to minimize the chattering and ensure the augmented system's performance in terms of robustness and stability. The proposed method is an improved version of DTC, which combines the addition of the Space Vector Machine (SVM) algorithm to the DTC and the increased number of DTC sectors that generate reference control voltages. Satisfactory results have been obtained by numerical simulation in MATLAB/Simulink. Eventually, the proposed method is proven to be a fast dynamic decoupled control that robustly responds to external disturbance and system uncertainties, especially in the low-speed range.

Application of linear induction motors (LIM) on enterprises of non-ferrous metallurgy involves accomplishing specific engineering and economic tasks of building a power unit of electric drive, engineering, modeling, designing, as well as technical and economic assessing of electric drive indicators. The paper presents an overview and analytical information on these issues, which allows industry specialists to perform a feasibility study of LIM usage. The prospects of LIM application in electric drives of processing and auxiliary equipment of non-ferrous metallurgy sub-sectors are justified and respective examples are given. The designing tasks of layout synthesis and calculation of the output characteristics with corresponding modeling aids are classified. It is established that there are no methods and means of solving both problems currently prevalent and accepted by professional community. Low operating rate of an electric drive and edge effects reduce energy data of LIM. At the same time, electric drives based on LIM or rotary motion electric motors are competitive variants of a linear electric drive. A mathematical model for layout synthesis of LIM is suggested. The model includes the means of forecasting estimation of electromagnetic, technical, weight-size and dynamic parameters of the object. On this basis, the main magnetic field of LIM was calculated. The LIM service life model calculation is implemented, what has allowed to evaluate cost-effectiveness of LIM application. It is established that in certain situations the use of a linear electric drive with LIM is advisable and cost-effective. The question of expediency of LIM usage in each concrete case should be settled based on a feasibility study.
