Abstract
A rotor is disclosed for a super-conducting synchronous machine comprising: a rotor core; a super-conducting coil extending around at least a portion of the rotor core, said coil having coil side sections on opposite sides of 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.
Claims30
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.
A rotor comprising:
- a rotor core having an axis;
- an end shaft [note:
- why just “an” end shaft, i.e. a “single”? Compare with claim 17] 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.
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.
A method for providing a vacuum around a super-conducting coil winding on a rotor core of a synchronous machine comprising the steps of:
- a. assembling the coil winding and rotor core;
- b. attaching end shafts coaxially to said core;
- c. straddling a vacuum housing over a side section of the coil winding and sealing the housing to said rotor core, and
- d. sealing the vacuum housing to said end shafts to form a vacuum region around said coil winding.
