Abstract
A rotor is disclosed for a synchronous machine comprising: a rotor core; a super-conducting coil winding extending around at least a portion of the rotor core, the coil winding having a pair of side sections on opposite sides of the rotor core; and a conductive shield around the rotor core and covering the coil winding.
Claims21
In a synchronous machine, a rotor comprising:
- a rotor core;
- a super-conducting coil winding extending around at least a portion of the rotor core, said coil winding having a pair of side sections on opposite sides of said rotor core;
- a conductive shield around the rotor core and covering said coil winding.
A method for shielding 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 ends of the rotor core to collars of end shafts coaxially aligned with the core, and
- c. installing a conductive shield around the rotor core, wherein the shield overlaps each of the collars.
A rotor for a synchronous machine comprising:
- a rotor core having a conduit orthogonal to a longitudinal axis of the rotor;
- a race-track super-conducting (SC) coil winding in a planar race-track shape parallel to the longitudinal axis of the rotor;
- a tension rod inside the conduit of the core;
- a housing coupling the coil winding to the tension rod, and
- a electromagnetic shield around the rotor core.
