Query: The Integration of YBCO 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 field, 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.
