Title:
SUPERCONDUCTING DIRECT-CURRENT MOTOR WITHOUT COMMUTATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/160514
Kind Code:
A1
Abstract:
A superconducting direct-current motor without a commutation device, comprising a housing (11) and a rotating shaft (12) penetrating through the housing (11). A rotor assembly located in the housing (11) is mounted on the rotating shaft (12); a stator assembly arranged around the rotor assembly is mounted in the housing (11); the stator assembly comprises a superconducting armature assembly; a superconducting shielding cover (21) is provided outside the superconducting armature assembly; a V-shaped groove protruding towards the superconducting armature assembly is formed on the peripheral wall of the superconducting shielding cover (21); a first cooling loop (22) is provided on the superconducting shielding cover (21); the housing (11) is provided with a first cooling port (23) communicated with the first cooling loop (22); and direct current is induced in the superconducting armature assembly, and also passes through the rotor assembly. Therefore, there is no alternating current loss in the superconducting armature assembly and the rotor assembly, thereby improving the mechanical efficiency of a superconducting motor, reducing the difficulty of manufacturing the superconducting motor, reducing the manufacturing cost and the operation cost, and further expanding the selection range of a superconducting wire.
