The Integration of YBACU3O6+X Coated Conductors into Magnets and Rotating Machinery

The implementation of the 2nd generation high‐Tc superconductors in power applications, such as electrical transformers, motors and generators requires superconducting wires that are superior to copper Litz wires at cryogenic temperatures in terms of losses in time‐varying magnetic fields, as well as in engineering current density. Another problem is to find a way to make practical coils and armatures out of flat tape‐like conductors with low bending strain tolerance. We discuss several novel approaches to the construction of coils and armatures based specifically on the properties of coated conductors manufactured today.
