Abstract
Tram systems for space vehicles are movable thereon. When the space vehicle is a nested ring cell, for example, the structural ring portion of the design may be mostly or completely passive and contain conducting parts, such as electrical steel. The moving trams may use field coils instead of magnets to generate the magnetic flux to propel the tram. Additional coils on the tram may steer the magnetic flux to generate the forward or reverse thrust forces. These coils may also add the overall motive flux.
