Eckels, P W

Cryostability is achieved by a superconductive rotor of a dynamoelectric machine constructed in accordance with the invention. The superconductive rotor comprises: a rotor shaft; a support rim; a plurality of slot teeth formed at the outer periphery of said rim, said teeth located between and defining a plurality of rotor slots; and a plurality of slot assemblies, one within each rotor slot. Each slot assembly comprises: a plurality of stacks of superconductors, each superconductor within a stack having insulation on only two of its sides and being disposed one on top of another in generally radial direction relative to the rotor shaft; a plurality of insulative separators, one between each pair of stacks; a top insulative strip and a bottom insulative strip, respectively radially above and below said conductor stacks; and a side panel on either side of the slot assembly and next to a slot tooth. Cooling channels are disposed on the surfaces of the separators, the side panels and the top and bottom strips so as to establish at least one coolant path along which coolant may be circulated to, within and from the slot assembly by natural convection.
