ABSTRACT:
A method and structure for restricting relative sliding motion at the interfaces between a superconducting winding and a supporting structure for the winding. An interface lining material having a low shear modulus of elasticity so as to accommodate large shear displacements with low shear stresses is used as opposed to the use of sliding frictional contact between the contacting surfaces of the electrical winding and the supporting structure. The invention is completed by subjecting the lined interfaced surfaces to large compressional pressure forces so that frictional forces between the interface material and the opposing superconducting winding and supporting structure surfaces, even at low coefficients of friction, are considerably higher than the internal shear forces of the interfacing lining material. The superconducting winding is comprised of a plurality of conductors of superconducting material bunched together in close thermal contact with each other and secured in a solid winding bundle by epoxy resin. The interface lining material preferably is wrapped completely around and surrounds the superconducting winding.
