In this paper, a sparse representation-based intuitionistic fuzzy clustering (SRIFC) approach is presented for solving the large-scale decision making (LSDM) problem. It consists of two algorithms: clustering-exactly precision algorithm (which an exactly requirement), and clustering-soft scalable proposed soft requirements). SRIFC approach, makers are clustered into several interest groups according to their preferences relation sparsity assessment information. The purpose investigate group...
An experimental platform of high temperature superconducting (HTS) synchronous motor with HTS flux pump has been designed and under construction. The as an exciter eliminates thermal load from the metal current leads, which will reduce cryogenic volume improve efficiency machine. A finite element model (FEM) using T-A formulation was developed to analyze electromagnetic characteristics a double-pancake (DP) racetrack coil. no-insulation (NI) coil wound by YBCO tapes fabricated winding...
To investigate the impact of applied magnetic field wavelength on pumped current, compact linear-motor type high temperature superconducting (HTS) flux pump devices two difference wavelengths were designed and built. These pumps are small in size, which generate DC-biased AC travelling waves, charge DC current into HTS closed-loop contactless manner. In this work, by comparing λ = 34.2 mm 21.0 mm, we had experimentally investigated how affects an insulated YBCO double pancake coil (DPC)....
This paper presents an electromagnetic design of a 1.5 T REBCO magnet for dedicated orthopedic magnetic resonance imaging (MRI). makes MRI portable as well cheaper. Due to the application no-insulation high temperature superconductor (HTS) technology, composed double-pancake coils (DPC) is highly compact; its outer diameter and axial length are both less than 300 mm, room-temperature bore 200 mm. On other hand, we used multiflux pumps charge DPCs separately reduce tape consumption costs...
High-temperature superconducting (HTS) flux pump can supply DC current into the magnet coil in a contactless manner. The works similarly as power supply, with low output voltage and high current. In this paper, based on linear-motor type previously introduced from our laboratory (W. Wang et al. 2018), we miniaturized it measured its voltage. By using different peak values frequencies of applied AC travelling magnetic wave, obtained pumping characteristics pump. With same strength, was found...
A high temperature superconducting (HTS) synchronous motor with brushless HTS flux pump exciters was designed and is under construction. This composed of copper armature windings, field exciters, vacuum chamber, rotary gas seal, etc. The double racetrack-type coils are wound second-generation (2G) YBCO tapes cooled directly by the cold heads. operation about 30 K. An to be used as DC power supply inject large currents into coils, which eliminates slip ring in avoids thermal load from current...
A high-temperature superconducting (HTS) no-insulation (NI) magnet charged by multiple flux pumps has been constructed and tested.

To avoid current limitation single DPC on whole fully use capacity each DPC, DPCs were 3 separate to provide different DC currents. rotor speed pump was controlled LABVIEW program microcontroller regulate charging central magnetic field, which...
This paper investigated the method of using multiple linear-motor flux pumps to increase central magnetic field an HTS magnet composed six stacking insulated YBCO double pancake coils. In this work, we compared two different excitation methods based on pumps, i.e., in series and segmented excitations, investigate their exciting performances magnet. Experiments showed that excitation, maximum operation current was limited by coil smallest critical current. On other hand, both each were...
This paper presents a Rogowski coil that can be used to measure the current in second-generation (2G) high-temperature superconducting (HTS) coils cryogenic environments.
