Abstract

Second generation (2G) high temperature superconductors (HTS) provide unparalleled capacity to pass electrical currents, with tape a centimetre wide and 2 microns thick able to carry hundreds of amps. This dramatic increase of current density over conventional wires allows for an incremental improvement in both motor and generator performance, yet to facilitate this requires dramatic changes in machine designs which have remained unchanged for many decades.

Cambridge University EPEC superconductivity group, headed by Dr. Tim Coombs, is a specialised research and development group which boasts significant academic expertise in the field of superconducting electrical machines. We will license the cut-edge technology to generator manufacturers supplying the growing wind energy and marine propulsion markets whilst continuing to innovate and lead development of this maturing technology.
