Recent Up-Scaling in HTS Magnetic Device Technology

High Temperature Superconducting (HTS) interaction shows a great potential in rotational bearing and linear Maglev technology. Besides the superconductor each application sets additional specific technical requirements. The challenges of use the various constructions and applications in the combination of the cold HTS material and the required technical periphery are discussed. ATZ's 0.5-ton HTS production per annum has enabled increased performance in a number of magnetic applications. Engineering properties, advanced magnetic excitation systems and thermal and mechanical stability of robust high-load YBCO bearings have been demonstrated. Effort is being made in the development of mobile HTS Maglev devices. We have designed and produced advanced 40-cm-long bulk cryostats, having 2-mm magnetic distance to the outside and operating more than one day without refilling. 24 vacuum cryostats have been manufactured for a magnetic train construction capable to transport up to 60-kN total vehicle and passenger weight and dedicated to operate on a 200-m-long track.
