Physica C: Superconductivity and its Applications   496 28-34   Jan 2014
© 2013 Elsevier B.V. We present a study on the investigation of the proper secondary phases for engineering magnetic flux pinning centers in textured Gd-Ba-Cu-O bulk superconductors. Compared with the joint TiO2 and BaO2 doping methods, the additi...

Journal of Physics: Conference Series   507    Jan 2014
The stability and durability of trapped flux is a focus in investigations of melt-growth (RE)Ba2Cu3O7-δ (RE=rare earth, e.g., Y, Gd, Sm) bulk high-temperature superconductors. In magnetic flux engineering applications, two important issues affect ...

Journal of Superconductivity and Novel Magnetism   27 1413-1417   Jan 2014
The trapped-flux dependence of bulk high-temperature superconductors between two typical working temperatures of 77 and 30 K was investigated by a field-cooling magnetization (FCM) method under a limited excitation field of 5 T to approach actual ...

International Journal of Modern Physics B   27    Jul 2013
The trapping process and saturation effect of trapped magnetic flux of bulk high-temperature superconductors by static field-cooling magnetization (FCM) are reported in the paper. With a cryogenic Bell Hall sensor attached on the center of the bul...

IEEE Transactions on Applied Superconductivity   23    May 2013
Intensified magnetic flux generated by high-temperature superconducting (HTS) windings makes feasible the industrial rotating machines with both high efficiency and high torque density. For those HTS windings, the superconducting characteristics a...

IEEE Transactions on Applied Superconductivity   23    Mar 2013
High-temperature superconducting (HTS) rotating machines generate higher torque density than the conventional ones, thanks to the intensified magnetic flux. The magnetic flux is coming from the large current through the HTS windings. However, the ...

IEEE Transactions on Applied Superconductivity   23    Mar 2013
The cooling of high-temperature superconducting (HTS) rotating machinery is essential in many ways: enhancing the properties of the HTS material, ensuring safe and stable rotation, nullifying the effects of heat invasion from the outside or of a p...

IEEE Transactions on Applied Superconductivity   23    Mar 2013
Commercial high-temperature superconducting (HTS) wires restrain us to an operation temperature ranging from 20 to 40 K for field-pole magnets applied to rotating machinery. We have proposed to employ a mixture of helium and neon gas in a closed-c...

IEEE Transactions on Applied Superconductivity   23    Mar 2013
We studied the axial-type synchronous generator with field pole bulk HTS magnets of GdBa2Cu3Oy to verify the behavior of the trapped magnetic flux due to ac field by the armature. For three different ratings 60, 120, and 240 rpm, the trapped flux,...

IEEE Transactions on Applied Superconductivity   23    Jan 2013
A series of REBa2Cu3Oy (RE123)/Ag bulk superconductors with multi-RE elements at the RE site, were prepared by top-seeded melt growth. By employing the differential thermal analysis, we carefully adjusted the peritectic decomposition temperature (...

Journal of the Cryogenic Society of Japan   46(3) 89-93   Mar 2011
In this article, the development progress of our GdBaCuO 30-kW-grade bulk HTS motor is presented. Two main features will be described here: the addition of the bulk HTS field poles using magnetic particles, and the amelioration of the condensed-ne...
