Description
Summary:Function elements can be constructed by cutting, machining and bonding of batch processed melt-textured YBCO. Depending on the application structures with different complex geometry can be fabricated. They consist of several monoliths, e.g. rings, bars and plates, and may be passivated, if necessary. Melt-textured YBCO monoliths with different shape and a maximum size of 60 mm can be reproducible prepared in a batch process. Seeding by self-made SmBa 2Cu 3O x leads to single domain material. Zero field cooled levitation forces at 77 K higher than 80 N were achieved. In single domain cylinders with a diameter of 30 mm and in quadratic shaped monoliths with an edge length of 35 mm maximum inductions of 1.3 and 1.2 T are frozen at 77 K. The trapped magnetic field of our function elements, e.g. plates and bars, are checked at 77 K. Results of our function elements in HTSC reluctance motors using single domain material are shown. Also, we will report about a fly wheel system, called “Dynastore” and a system to levitate persons.
