Abstract
A rotor is disclosed for a super-conducting synchronous machine having: a rotor core; a super-conducting coil extending around at least a portion of the rotor core, the coil having coil side sections on opposite sides of the rotor core; a vacuum housing covering at least one of the coil side sections, and a conductive shield over the vacuum housing and coil side sections.
Claims23
In a synchronous machine, a rotor comprising:
- a rotor core;
- a super-conducting coil mounted on said rotor core;
- a vacuum housing covering at least one of said coil side sections, and
- a conductive shield over said vacuum housing and coil side sections.
1 more element
A rotor comprising:
- a rotor core having an axis;
- an end shaft extending axially from an end of said core, wherein said end shaft has a slot adjacent the core end;
- a super-conducting rotor coil having at least one coil side parallel to the core axis and at least one coil end transverse to said core axis, wherein said coil end extends through said slot in the end shaft;
- a vacuum housing over said coil side and seal with said slot to define a vacuum region around said coil.
1 more element
A rotor comprising:
- a rotor core having an axis;
- a pair of end shafts extending axially from opposite ends of said core, wherein said end shafts each have a slot adjacent the core end;
- a super-conducting rotor coil having at least one coil side section parallel to the core axis and adjacent opposite sides of said core, and said coil having coil end sections transverse to said core axis and adjacent the ends of said core, wherein said coil end sections each extend through one of said slots in the end shafts;
- a vacuum housing over each said coil side sections and having ends each being sealed to one of slots, and
- a vacuum region around said coil defined by said the slot in said pair of end shafts and the vacuum housing over each of said coil side sections.
