Title:
ROTOR OF SUPERCONDUCTING ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2023112554
Kind Code:
A
Abstract:
To make it possible to provide a feedthrough so as to maintain a vacuum state in a rotor even when a diameter of a center hole of a rotor shaft is small, and transmit a measurement signal to the outside by passing wiring through the feedthrough.SOLUTION: A rotor of a superconducting rotary electric machine according to an embodiment includes a feedthrough through which wiring for supplying a measurement signal measured by a sensor provided in a superconducting rotor to the outside is passed, and a feedthrough attachment member having a center hole to which the feedthrough is attached, and being joined to a shaft of the superconducting rotor in a rotor shaft direction. The center hole of the feedthrough attachment member has a first center hole portion in which the feedthrough is disposed and a second center hole portion having a diameter smaller than that of the feedthrough and corresponding to that of the center hole of the shaft of the superconducting rotor.SELECTED DRAWING: Figure 2
