CALCULATION AND MATHEMATICAL MODELING OF ELECTROMAGNETIC TRACTION CHARACTERISTICS OF THE DRIVE WORKING AUTHORITY OF OIL EXTRACTION INSTALLATIONS ON THE BASE OF A COAXIAL-LINEAR INDUCTION MOTOR

Today, a promising direction in the development of the field of application of linear motors is their use in the construction of well pumps. This makes it possible to significantly increase the stroke of the working body and improve the efficiency of oil production compared to the traditionally used rod-well analog. When solving such a problem, a dif-ficult issue is forecasting and ensuring the traction force during the working trajectory of the movement, which is what the research conducted in the work is aimed at. As the main result, the application of the grapho-analytical method in the calculations and modeling of the characteristics of linear motors with complex trajectories of motion is substanti-ated. In the course of calculations with its use, the possibility of a four-fold increase in the traction force with a general improvement in the static characteristics of the engine in a given range of movement at the permissible speed of the working body was proven.
