摘要

The replacement of steam catapults with electromagnetic ones is becoming an overwhelming trend in aircraft launch systems. Recently, the double-sided linear launcher has attracted more and more attention from researchers. This paper presents the design and analysis of the moving-magnet-type permanent-magnet linear synchronous motor (PMLSM). The thrust density is the most important indicator for a powerful motor, so an analytical expression of the thrust-density coefficient is derived from basic electromagnetic force laws. Based on the analytical results, the thrust and the thrust ripple are analyzed using the finite element method in different conditions. In order to modularize easily, the ring windings have been applied in the double-sided PMLSM, and then, the design features and parameter optimization of the windings are discussed. This paper can provide references to select the suitable type of motor for the launch systems and accomplish the fundamental work for the design of a prototype.
