Title:
SUPERCONDUCTIVE ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS6026459
Kind Code:
A
Abstract:
PURPOSE:To improve the reliability by concentrically disposing a radiation heat shielding member 21 provided with a coolant passage at the outside of a torque cylinder formed with a coolant chamber. CONSTITUTION:An outer cylinder 2 which operates also as a normal temperature shielding cylinder and a supporting member 3 are integrally interposed between shafts 1a and 1b of a superconductive rotor. A vacuum chamber 4 is formed in the cylinder 2, and a pair of heat exchangers 5, 6 and a torque cylinder 8 which contains a superconductive electromagnet 7 are secured between the member 3 in the chamber 4 and the inside of the shaft 1a. A coolant chamber 9 is formed in the cylinder 8, and a radiation heat shielding cylinder 21 of double cylindrical shape formed with a coolant passage 21a is concentrically provided to form a vacuum layer 14 in the chamber 4. The exchangers 5, 6 connected to the chamber 9 and the passage 21a of the member 31 are connected via conduits 22, 23.
