Abstract
Tram systems for space vehicles are disclosed. 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.
Claims27
A movable tram for a space vehicle, comprising:
- control electronics configured to control operation of the movable tram, wherein
- the movable tram is configured to move along at least a portion of a track of a space vehicle, and
- the movable tram is configured to:
- connect to at least one other space vehicle, at least one other tram of another space vehicle, at least one other structure, or any combination thereof,
- provide power, data, fuel, heat, or any combination thereof, to at least one other space vehicle,
- act as a support structure that holds external components that can be articulated, or
- any combination of the above.
4 more elements
A movable tram, comprising:
- a primary coil;
- a plurality of armature teeth;
- respective motor coils wound around the plurality of armature teeth on an end of the armature teeth closest to a conducting track;
- and
- control electronics configured to perform motor commutation and control operation of the movable tram, wherein
- the movable tram is a component of a space vehicle.

A movable tram, comprising:
- a primary coil;
- a plurality of armature teeth;
- respective motor coils wound around the plurality of armature teeth on an end of the armature teeth closest to a conducting track;
- control electronics configured to perform motor commutation and control operation of the movable tram;
- and
- a mechanical system configured to hold the tram on the conducting track when the primary coil and the motor coils are not powered on, wherein
- the movable tram is a component of a space vehicle.
