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, 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 and abutting the side section of the coil winding; and a channel housing attached to the tension bolt and the coil winding.
Claims23
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, and
- a housing attached to the tension bolt and connected to the side section of the coil winding.
A method for supporting a super-conducting coil winding in the rotor core of a synchronous machine comprising the steps of:
- a. extending a tension rod through a conduit in said rotor core;
- b. inserting at least one tension bolt into an end of the rod;
- c. assembling at least one housing around one of the side sections of the coil winding;
- d. positioning the coil winding with housing around the rotor core such that the tension rod and tension bolt span between side sections of the coil winding with housing, and
- e. securing the bolt to one of the housings.
A rotor for a synchronous machine comprising:
- a rotor core having a conduit;
- a race-track super-conducting (SC) coil winding in a race-track in a plane parallel to a longitudinal axis of the rotor;
- a tension rod in the conduit of the core;
- a tension bolt in each end of said tension rod, and
- a housing coupling the coil winding to each tension bolt.
