    摘要： Locking strips secure winding modules to a rotor. The locking strips have paired deep and shallow recesses along a long edge and are disposed in a groove along the rotor. Upon assembly of the winding module, the deep recesses of the locking strips are aligned, enabling the winding supports of the winding module to engage in the deep recesses. The strips are then axially displaced in opposite directions relative to one another to engage portions of the strips within grooves of the winding supports and edges of the shallow recesses to straddle the winding supports. Pins are received in aligned holes of the locking strips in the locked configuration. Consequently, the modular winding is retained against axial and peripheral movement and outward displacement along a parallel face of the rotor shaft.

    摘要： A method is disclosed for fitting a rotor enclosure over at least one assembly of field windings mounted on a rotor core, said method comprising the steps: applying a force to elastically reduce a circumference of the at least one assembly of field windings mounted on the rotor core, where the reduction in circumference is greater than a circumference reduction due to just eliminating clearances between adjacent end-turns of windings; generating a clearance between the field windings and the rotor enclosure due to the application of the force; axially sliding the rotor enclosure over the at least one assembly of field windings while the circumference is reduced, and releasing the force to allow the circumference of the at least one assembly of field windings to expand and cause the enclosure to tightly fit on the at least one assembly of field windings.

    摘要： A cooling fluid coupling is disclosed for providing cooling fluid to a rotor having a super-conducting winding of a synchronous machine and a source of cryogenic cooling fluid. The fluid coupling comprises an inlet cooling tube and an outlet cooling tube in the rotor and coaxial with an axis of the rotor. The inlet cooling tube has an input port coupled to receive inlet cooling fluid from the source of cryogenic cooling fluid. The outlet cooling tube has an output port coupled to return cooling fluid from the rotor to source. A stationary motion gap seal separates the input port and output port of the coupling.
