This article presents a comprehensive analysis of electromagnetic and structural errors that occur in toroidal core linear motion systems and evaluates their influence on the operational accuracy and stability of the device. Linear motion drives based on toroidal cores are widely used in modern electromechanical and mechatronic systems thanks to their compact structure, high efficiency and ability to generate stable electromagnetic forces. However, various electromagnetic and constructive imperfections that arise during the design and manufacturing processes can have a negative impact on system performance, positioning accuracy and dynamic characteristics. So, finding and fixing these mistakes is an important job for scientists and engineers. The primary aim of this research is to identify the essential parameters that guarantee stable traction force generation, diminish vibration levels, and enhance positioning accuracy in toroidal core drives. The study focuses on the effects of magnetic flux distribution, air-gap geometry, winding symmetry, magnetic saturation, and structural alignment on the system's electromagnetic behavior. The study further investigates how fluctuations in these parameters result in alterations of electromagnetic force, energy dissipation, and dynamic instability within the motion system. Mathematical modeling and simulation techniques were utilized to examine the electromagnetic phenomena in toroidal core structures, aiming to fulfill the research objectives. We then checked and compared these results with experimental data to see how different sources of error affected system performance. We paid special attention to studying the drive system's dynamic properties, like how stable the force is, how it vibrates, and how accurately it responds while it's running. The findings demonstrate that enhancing the structural precision of the toroidal core, optimizing magnetic flux distribution, and employing advanced control algorithms can markedly improve the performance, reliability, and positional accuracy of linear motion systems. Also, reducing the difference in windings and carefully designing the air-gap geometry makes electromagnetic distortions and vibrations less noticeable. This research gives scientists and engineers a scientific and practical way to design, improve, and control toroidal core linear motion drives. The suggested methods and analytical findings can be effectively utilized in the advancement of high-precision electromechanical systems for industrial automation, robotics, precision positioning devices, and cutting-edge mechatronic technologies.
