Abstract
A rotor for a synchronous machine is disclosed comprising: a rotor; a super-conducting coil winding extending around at least a portion of the rotor, said coil winding having a pair of side sections on opposite sides of said rotor; at least one tension rod extending between the pair of side sections of the coil winding and through conduits in said rotor; and a coil housing at each of opposite ends of said tension rod, wherein said coil housing wraps around said coil winding and is attached to said tension rod.
Claims27
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;
- at least one tension rod extending between the pair of side sections of the coil winding and through said rotor;
- a coil housing at each of opposite ends of said tension rod, wherein said housing wraps around said coil winding and is attached to said tension rod.
A method for supporting a super-conducting coil winding on a rotor core of a synchronous machine comprising the steps of:
- a. extending a tension bar through a conduit in said rotor core;
- b. inserting a housing over a portion of the coil;
- c. attaching an end of the tension bar to the housing.
A rotor for a synchronous machine comprising:
- a rotor core having a conduit orthogonal to a longitudinal axis of the rotor;
- a racetrack super-conducting (SC) coil winding in a planar racetrack shape parallel to the longitudinal axis of the rotor;
- a tension rod inside the conduit of the core;
- and
- a housing coupling the coil winding to the tension rod.
