Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
89 words
A method for supporting a super-conducting coil winding in the rotor core of a synchronous machine comprising: a. extending a tension rod through a conduit in said rotor core; b. positioning the coil winding around the rotor core such that the tension rod spans between side sections of the coil winding; c. assembling a pair of side panels of at least one housing around a side section of the coil winding; d. securing side panels together, and e. attaching the housing to a first end of the tension rod.
Claim 2
Independent Claim
89 words
A method for supporting a super-conducting coil winding in the rotor core of a synchronous machine comprising: a. extending a tension rod through a conduit in said rotor core; b. positioning the coil winding around the rotor core such that the tension rod spans between side sections of the coil winding; c. assembling a pair of side panels of at least one housing around a side section of the coil winding; d. securing side panels together, and e. attaching the housing to a first end of the tension rod.
Claim 3
Dependent Claim
33 words
A method as in claim 1 further comprising repeating steps (c) and (d) to secure a second housing around the side section of the coil to a second end of the tension rod.
Claim 4
Dependent Claim
30 words
A method as in claim 1 wherein step (c) is performed by assembling a plurality of side panels around an a flange head at an end of the tension rod.
Claim 5
Dependent Claim
35 words
A method as in claim 1 wherein step (c) is performed by assembling a plurality of side panels to form a serrated hole and engaging a serrated end of the tension rod into the hole.
Claim 6
Dependent Claim
27 words
A method as in claim 1 wherein several tension rods are inserted into a series of conduits in the rotor core and secured to the coil winding.
