Abstract: A magnetic levitation test system and an electromagnet test method. A vehicle-mounted controller (1024), an electromagnet controller, and an electromagnet are subjected to joint test by means of the magnetic levitation test system integrated with a vehicle-mounted controller test bed (102), an electromagnet controller test bed (104), and an electromagnet test bed (106). The running condition of a train can be simulated, and the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are subjected to joint test under the simulated running condition of the train. Therefore, the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are subjected to function verification, thereby reducing the fault rate when the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are used at the same time.
Abstract: A winding for use in a superconducting electric generator having a rotating rotor assembly surrounded by a non-rotating stator assembly is provided. The winding comprises at least one conductor structure associated with a component in the superconducting electric generator. The conductor structure comprises a plurality of conductive elements formed from a high temperature superconductive material. At least a portion of the conductive elements is arranged in a transposed relationship. A protective shell is positioned about the conductive elements and formed from a high strength alloy suitable for cryogenic temperatures.
Abstract: A magnetic thrust bearing (110) comprises a magnet (112) mounted on a shaft (114) and a plurality of equi-angularly spaced superconductors (116) mounted on a static structure (118). Each superconductor (116) is mounted onto the static structure (118) by a parallel hinge strip (120) which allows the superconductor (116) to move radially relative to the axis of rotation of the shaft (114). The radial movement of the superconductors (116) changes the cross-sectional area of the magnetic field between the magnet and the superconductors (116) and this changes the stiffness of the magnetic bearing (110). The superconductors (116) move radially due to the pivoting of the parallel hinge strips (120) due to changes in the loads acting on the magnetic bearing (110). It is possible to detect movement of the shaft and to actively move the superconductors to control the stiffness of the magnetic bearing and to control the clearance in the magnetic bearing as in FIG. 5.
