Relaxation of Levitation Force of a Stack of HTS Tapes
IEEE Transactions on Applied Superconductivity, 2016Nowadays, magnetic bearings are used to design motors, generators, separating platforms, and flywheel energy storage systems. High-temperature superconducting (HTS) magnetic bearing construction is based on YBa 2 Cu 3 O 7-x (YBCO) bulks through its ability to capture and hold significant magnetic field for a long time.

The Levitation Force Characteristics of Stacked HTS Tapes
2020 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2020High temperature superconducting (HTS) tapes can be stacked into a block structure and be used in HTS magnetic levitation systems. This paper proposes a simulation method based on H-formulation to study the levitation force characteristics of the stacked HTS tapes on the permanent magnet guideways (PMG) in Comsol Multiphysics.

Levitation Force of Magnetized HTS Tape Stacks
IEEE Transactions on Applied Superconductivity, 2017High-temperature superconductors (HTS) have the significant potential of magnetic-force-based applications. Nowadays, wide spread of coated conductors tapes (CC-tapes) enables the use of HTS stacks in levitation applications. For the development of CC-tapes-based bearings and transportation systems, it is important to have information on stability of ...

Stresses and strains in multi-filament HTS tapes
IEEE Transactions on Appiled Superconductivity, 1999High temperature superconducting tapes are now commercially available for practical applications such as magnets and cables. However, still today the published data on strength and allowable deformation limits of these tapes are not altogether in agreement. Definitions and concepts with regards to the stresses and strains in HTS tapes under deformation

Reduction of Magnetization in Windings Composed of HTS Tapes
IEEE Transactions on Applied Superconductivity, 2012Methods to reduce the magnetization in windings composed of high temperature superconductor (HTS) tapes are presented on the basis of the abnormal transverse-field effect. The toroidal arrangement as well as the coaxial arrangement of additional coils wound with non-magnetic wires such as copper wires is effective to uniformize the distribution of ...

Critical Current of the HTS Winding Wound With 12 mm YBCO HTS Tape
IEEE Transactions on Applied Superconductivity, 2013Wide 12-mm high-temperature superconducting (HTS) tapes are being used for HTS windings. The critical current of an HTS winding with a 12-mm HTS tape is calculated in this paper, with consideration of the nonuniform current distribution at the cross-section of the HTS tape.
