Objective This Brite EuRam project has successfully developed reliable and reproducible processing technologies for smaller sized optimized melt-textured monolithic YBaCuO high-temperature superconductors. Furthermore, a down-scaled demonstrator unit for an inertial energy storage system with a circumferencial inherently stable suspension has been designed, constructed and tested using these monolithic superconductors. The industrial and commercial impact of this project lies in paving the way for a reliable processing technology for melt-textured superconductors within Europe as well as demonstrating their potential for and beyond the flywheel technology.The aim of the proposed research is to develop improved bulk YBCO materials with respect to applications in magnetic levitation technology and energy conversion. For this purpose, various methods for growing melt-textured YBCO material will be applied, lie vertical gradient freeze (VGF), modified Bridgman method, top seeding, microwave sintering and slow cooling with small temperature gradients. The dependence of micro structural properties of the material on different growth parameters and precursor material properties will be carefully investigated. This is aimed at the development of large (several cm{3}) YBCO monoliths with sufficiently high critical current densities (>5.104 A/cm{2} at T=77K and fields up to 2 T) for the application also in large magnetic bearing systems and improved electrical power conversion. This will be demonstrated by the development of1) a downside demonstrator for inertial energy storage with circumferencial suspension 2) a linear motor to demonstrate improved power conversion by magnetic field conditioning using melt-texture YBCO material. The research work will lead to the definition of criteria for industrial production of large, highly textured YBCO materials for applications.
