Repulsorlift/Legends
The repulsorlift or repulsorlift engine, often referred to simply as a repulsor, was an anti-gravity technology capable of levitating an object. It was created from subnuclear "knots" of space-time made by enormous unmanned power refineries encompassing black holes.[1] Repulsorlifts were widely used, and were included on virtually every type of vehicle.
Description
Repulsorlifts only worked within a gravity well, as the technology required mass to push against. For a typical habitable planet such as Alderaan, "antigrav range" was approximately six planetary diameters, or around seventy-five thousand kilometers. Repulsorlifts used minimal power and were reliable enough to be utilized continuously.
Repulsorlifts could be assembled in arrays, clusters, or vanes studded with micro-coils of gravitic "knots". These units were then mounted on a vehicle or spacecraft, usually on the underside. The many repulsorlifts needed for a large ship were typically powered by a dedicated "antigrav generator."[1]

Vehicles that commonly employed repulsors include speeder bikes, swoops, landspeeders, airspeeders and starships capable of operating in Gravity Wells. Power chairs, repulsorsleds and skimboards also used this technology.
History
The five planets of the Corellian system possessed massive repulsors on their surface. They were so powerful that they could destroy capital ships in nearby space, and even stop the devastating firepower of Centerpoint Station, which created gravitational shifts great enough to destroy stars.
The Verpine of the Roche asteroids utilized repulsorlifts in asteroid shepherding.
