Abstract
The end turn region of a superconducting rotor is provided with end region support blocks that together provide channels for coil location. Within the support block channels there are intermittent supports in the form of insulating spacers extending radially both to the front and to the rear of the coil and also bottom spacers, with sheets of side insulation between the front and rear spacers and the adjacent support blocks. The intermittent supports provide access of coolant to the superconductor. They may also be formed in a manner to tilt the end region toward the pole piece for better mechanical support. A top insulating spacer is provided with cooling channels and is utilized with banding to provide secure compressive support for the end windings. Apertures in the support blocks and grooves in the spacers provide collant circulation.
