In this work, a fully high temperature superconducting reluctance motor (HTS RM) is studied. A smallest configuration of HTS armature winding based on the mechanical characteristics of HTS BSCCO tape is determined. Furthermore, a novel rotor topology of single HTS YBCO bulk with ferromagnetic material is proposed. Electromagnetic torque of HTS RM is calculated by finite element method (FEM) with 2D consideration. The characteristics of the bipolar HTS RM are compared with a conventional motor with HTS rotor.

Purpose: The paper concerns the determination of the chemical composition and structure of high-temperature superconducting tapes YBa2Cu3O7-x– YBCO/Cu 2G HTS. Design/methodology/approach: Studies were carried outusing a scanning electron microscope with a chemical composition analyser on prepared samples of a tape. Moreover, an abrasion resistance test which shown resistance to friction at 1, 2 and 3 hours by using ball-tester was carried out. The individual layers which are components of the test tape and depths of wipes which appeared after test on ball-tester were evaluated. Findings: Studies showed a lot of information about abrasion resistance of tapes. Hourly friction, using ceramic ball did not result in breakthrough coating. The investigation are carried out for one, two and three hours. They also confirmed the chemical compositions provided by the manufacturer, as well as describe the individual layers of examined superconducting tapes. Originality/value: Detailed studies in particular, on wear resistance of superconductors, which relate to the chemical composition of the tapes, and their construction carried out in the context of the article, may be a prelude to further research into the production of superconducting tapes that will show much greater resistance to abrasion. The essence of the problem is a construction base, in particular during the installation of such tapes, for example in the form of a transformer winding.
