The advantages of superconductivity are “zero electrical resistivity” and “high current density”. The critical temperature of high-temperature superconductors(HTS) exceeds liquid nitrogen temperature of -196℃. HTS should bring about electric machines and devices with light weight, compactness and high efficiency. We aim to apply the superconductor technology to a variety of industrial field.

  1. Development of superconducting electric power machines and devices: Superconducting transformers and cables with a current limiting function have been developed and demonstrated in a real power-grid scale. Superconducting rotating machines with compactness, light weight and high efficiency are developed for electric aircrafts and ships, and also industrial uses.
  2. Investigation of the electromagnetic properties of HTS wires and coils: Electromagnetic properties of HTS wires with anisotropy are quantitatively investigated by using a saddle-shaped pickup coil which were studied out in our laboratory. On the basis of observed properties, new configuration of wires and windings are proposed for AC loss reduction and current-capacity enhancement and the performance is demonstrated by making a small model.
