Methods of research of linear motors used in cutting systems

This paper presents a comprehensive analysis of the research methods and modeling techniques for linear induction motors (LIMs) used in modern cutting systems. Special attention is given to cylindrical LIMs, which offer significant advantages such as high positioning accuracy, reduced energy losses, and the elimination of mechanical conversion components. The study considers analytical and numerical approaches, as well as modeling based on magnetic equivalent circuits. For model validation, software tools such as MATLAB/Simulink, FEMLAB, and ELCUT were employed to evaluate the drive’s dynamic, electromechanical, and transient characteristics. Functional schemes for the programmable logic controller (PLC), power section, and control algorithms of the cutting system are developed. The results demonstrate the efficiency of LIMs in industrial automation tasks and highlight their potential to improve the reliability and energy efficiency of electromechanical drives. The findings have practical relevance for the design of intelligent control systems in mechatronics and robotics applications.
