Cost-Effective Force Distribution Optimization in Segmented LSRMs for Enhanced Electric Train Propulsion Performance and Reliability

Linear motors have garnered significant attention in various industrial applications due to their simple structure and capability for direct motion. However, traditional designs of linear motors often face challenges in achieving optimal system performance. This paper introduces a modern structural framework that optimizes force distribution in a segmented linear switched reluctance motor, addressing some of the limitations associated with traditional designs. These types of motors are the most cost-effective electric motors that have gained considerable attention in recent years. The proposed structure leads to improved force distribution and force quality while significantly reducing force ripple effects, resulting in smoother motion. With the enhanced quality of propulsion force and a considerable reduction in force ripple, the proposed structure can be highly beneficial in industrial systems such as electric trains and elevators, and it can compete with other conventional electric motors. The proposed system not only achieves optimal force distribution but also enhances system reliability, allowing the motor to continue functioning in the presence of a fault in one of its phases. Simulation and experimental results confirm the superior performance of the proposed system compared to conventional systems.
