“…The main disadvantage of linear asynchronous electric motors is low energy performance due to the openness of the magnetic circuit of the inductor along the longitudinal axis [8][9][10][11][12][13]. Also, in this regard, the analysis of electromagnetic processes in linear induction motors (LIM) due to a number of their features is quite complicated [8][9][10][11][12][13][14][15][16][17].…”

“…The analysis of a number of basic drive characteristics of technological equipment of agricultural production showed that the drive of a number of working bodies that perform translational and oscillatory movements, as well as rotational movement with a rotation speed of up to 500 rpm, is effectively, from the point of view of energy and resource saving, carried out using special electromechanical and electromagnetic converters -induction electric drives with a motor with an open magnetic circuit. The optimal choice of an induction motor with an open magnetic circuit makes it possible to obtain the necessary technologically specified drive characteristics, to achieve the integration of the elements of the electric motor with the working body with the complete exclusion of mechanical converters, as a result of which material and energy consumption are reduced, and the performance of technological equipment of agricultural production as a whole is increased [3][4][5][6][7][8][9][10][11].…”

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.

“…A systematic approach, analysis from the standpoint of the greatest efficiency for the entire national economy leads to the conclusion that the total mass, overall dimensions and cost with the indicated traditional solution of the electric motor and gearbox in a fairly large class of applications differ very significantly from the corresponding parameters of the electric motors themselves. Consideration of the main alternative -gearless electric drives (ie electric motors directly connected to the working mechanism) is of significant interest [1][2][3][4]. The task of creating a gearless electric drive can be solved while maintaining the principle of «movement of the driving and driven element in the same coordinate».…”

“…These are multi-pole machines powered by an industrial network or a low-frequency source, machines with a rolling rotor, machines powered by a rotor and stator from sources with different frequencies, gear motors, machines operating on magnetic field subharmonics. The same characteristics have been widely developed in recent years induction motors with an open magnetic circuit (linear, arc and end motors) [1][2][3][4][5][6].…”

Linear asynchronous electric motors drive the working bodies of the mechanisms directly and quite fully fulfill their drive characteristics, allow eliminating mechanical converters and increase performance. This solves the problem of maximum articulation, splicing of a source of mechanical energy - an electric motor and an executive technological mechanism. Linear electric motors with a massive ferromagnetic secondary are the most cost-effective, taking into account the operating modes - when operating in starting modes and on stop, therefore, in practice, it often becomes necessary to calculate them in a short circuit mode. With a simplified calculation, it is convenient to use correction factors for increasing magnetic fluxes in the yoke, secondary losses and efforts of linear induction motors compared to the same values in a circular analogue. The dependences of such coefficients on the quality factor, the number of pairs of poles and the relative magnetic resistance of shunting. In the general case, the comparison and selection of the design of a linear induction motor is carried out at the stage of preliminary design using the optimality criteria - the quality factor.
