“…It has also been suggested that the diamagnetic property of bulk superconductors can improve the efficiency and power factor of reluctance motors 47–49 . The concept for the bulk RE–Ba–Cu–O reluctance motor is to construct the rotor with a composite of ferromagnetic and bulk RE–Ba–Cu–O layers.…”

I will summarize the current status of processing and applications of bulk high‐temperature RE–Ba–Cu–O (RE: rare‐earth elements) superconductors. Recent advancement of processing techniques led to the production of single‐grain RE–Ba–Cu–O superconductors >10 cm in diameter. The maximum‐trapped field values of single‐grain RE–Ba–Cu–O are 4 T at 77 K, 9 T at 46 K, and 17 T at 29 K. The mechanical properties as well as thermal stability were greatly improved through impregnation of metals and resin, which is highly important for practical engineering applications. Industrial applications of bulk RE–Ba–Cu–O can be categorized into three major regions: levitation, trapped field magnets, and conductors. Stable levitation without active control has been used for non‐contact bearings of a flywheel energy storage system, levitated vehicles, and non‐contact mixers. Trapped field magnets are used for a field generator, a magnetic separator for water purification, a magnetron‐sputtering device, a nuclear magnetic resonance spectrometer, and an undulator. Bulk RE–Ba–Cu–O is also used as conductors like current leads and resistive fault current limiters.

“…Therefore, this research direction is useful. In the past, Oswald et al designed a cylindrical linear synchronous motor with a BSSCO wire-wound armature [10][11][12]. Next Kellers et al produced a cylindrical linear induction motor including a BSSCO wire-wound armature and a copper mover [13].…”

“…Because the armature is made of HTS windings, AC losses also existed. However, Oswald et al had an idea that the excitation system of the cylindrical linear synchronous motor could also use HTS materials [10].…”

“…Textured Y-Ba-Cu-O bulk superconductors continue to hold promise for important new technological applications including high power density motors/generators, levitators, flywheels and fault current limiters [1][2][3]. In order to increase the performance of these devices, further improvements of both the critical current density and the size of the single domain Y-Ba-Cu-O superconductors are necessary.…”
