ROTOR FOR SUPERCONDUCTING DYNAMO-ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a rotor for superconducting dynamo-electric machine wherein stress on the base side (inner radius side) of tooth portions due to centrifugal force exerted on field winding or circumferential electromagnetic force is reduced. SOLUTION: The rotor for superconducting dynamo-electric machine is provided with slot lids which are engaged with the side walls of tooth portions on both sides of open slots and close the open slots so as to prevent the field winding from flying out. A pair of engaging portions which can be slid in the direction of the axis of a field winding installation shaft and cannot be rotated in the direction of the circumference thereof are placed on the top faces of the tooth portions of the field winding installation shaft, and on the inner circumferential surface of a cylindrical body.
