Abstract
A rotor for a synchronous machine is disclosed comprising: a cylindrical magnetic solid rotor core; a race-track super-conducting coil winding extending around the rotor core; a coil support extending through the core and attaching to opposite long sides of the coil winding, and a pair of end shafts extending axially from said core and attached to the core.
Claims21
A rotor for a synchronous machine comprising
- a cylindrical magnetic solid rotor core having at least one conduit extending through the core and perpendicular to a core axis;
- a race-track super-conducting coil winding extending around the rotor core, wherein said coil winding is in a plane of the at least one conduit;
- a coil support extending through the at least one conduit of the core and attaching to opposite long sides of the coil winding, wherein a gap is between said coil support and said conduit such that the coil support is thermally isolated from said conduit, and
- a pair of end shafts extending axially from said core and attached to the core.

In a synchronous machine, a rotor comprising:
- a cylindrical rotor core having a pair of planer sections on opposite sides of the core and extending longitudinally along the core, at least one conduit extending through said core and having openings on each of said planer sections;
- a super-conducting coil winding extending around at least a portion of the rotor core, said coil winding having a pair of side sections adjacent said planer sections of the core, and said side sections aligned with the openings of the at least one conduit;
- a coil support extending through the at least one conduit and attached to the side sections of the coil winding wherein said coil support is thermally isolated from the rotor core;
- a first end shaft extending axially from a first end of the rotor core, and
- a second end shaft extending axially from a second end of the rotor core.
