The system vibration caused by thrust ripple in double-sided linear induction motors (DSLIMs) is an urgent problem to be solved in precision control fields such as high-speed electromagnetic propulsion, rail transit, and industrial drives. An in-depth study on the secondary structure of DSLIMs was conducted, and an arrow-shaped secondary design was proposed to reduce thrust ripple. First, the key shape parameters of the arrow-shaped secondary design were derived. Three-dimensional finite element models of DSLIMs incorporating flat, square-misaligned, and arrow-shaped secondary designs were established to analyze their thrust output characteristics. Then, the eddy current distribution features and layered thrust distribution characteristics of different secondary structures were compared to elucidate the mechanism of thrust ripple suppression by the arrow-shaped secondary design. Finally, the thrust of the arrow-shaped secondary structure before and after optimization under motion conditions was compared using a three-dimensional transient finite element model. The results indicate that the optimized arrow-shaped secondary design improves the utilization of secondary conductors and enhances the thrust ripple suppression effect by optimizing the eddy current path in the end regions. In the region near the operational slip, the thrust ripple rate can be reduced to below 2%, and the thrust under the same mass can reach 21.51 kN, representing an increase of 1.03% compared with the square-misaligned secondary design.
