Super-conducting rotor coil support with tension rods and bolts

In a synchronous machine, a rotor comprising:

• a rotor core;
• a super-conducting coil winding extending around at least a portion of the rotor, said coil winding having a side section adjacent a side of the rotor core;
• at least one tension rod extending through a conduit in said rotor core;
• at least one tension bolt extending between an end of the tension rod;
• a housing attached to the tension bolt and connected to the side section of the coil winding, and
• wherein the housing comprises side panels bracketing the side section of the coil, and wedge between the side panels and abutting an outside surface of the side section.

A rotor for a synchronous machine comprising:

• a rotor core having a conduit, wherein the conduit extends through the core and is perpendicular to an axis of the core;
• a race-track super-conducting (SC) coil winding in a race-track in a plane parallel to a longitudinal axis of the rotor, wherein the conduit is parallel to the plane of the coil winding;
• a tension rod in the conduit of the core, wherein said tension rod is parallel to the plane of the coil winding and perpendicular to the rotor axis;
• a tension bolt in each end of said tension rod, and
• a housing coupling the coil winding to each tension bolt.
