Abstract: Considering the complex structure of existing recuperators, which often struggle to meet the real-time controllability requirements of the recuperation process, this paper proposes an electromagnetic recuperator based on the principle of a double primary tubular permanent magnet synchronous linear motor (DP-TPMSLM). By analyzing the forces acting on each component during the recuperation process, the differential equations governing the recuperation motion are established, and the magnitude of the required recuperator force is clarified. For the DP-TPMSLM, the decoupling of cogging and end effects, along with improvements to the end structure, effectively suppresses both the fundamental and second harmonics of the detent force, resulting in a significant reduction in thrust fluctuations, as verified by experiments conducted with a small-scale prototype. Furthermore, an electromagnetic recuperator based on the principle of DP-TPMSLM is proposed and a joint simulation study is carried out by applying it to a vehicle-mounted gun system. The experimental and simulation results demonstrate that the detent force of the improved DP-TPMSLM has been reduced to 465.9 N, representing an 34.4% decrease compared to the unimproved structure. Furthermore, the proposed electromagnetic recuperator effectively achieves real-time control of the recuperation process, fundamentally addressing the issue of collision between the breech ring and the cradle.
