Abstract:
Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating
machines (SuperMotors and SuperGenerators) that can generically be categorized as SuperMachines. Compared to
conventional machines of equivalent rating, these SuperMachines are expected to be less expensive, lighter, more
compact, efficient, and provide significantly superior stable operation in a power system. The field windings are
made with HTS conductor material (BSCCO, or Bi-2223) which operates at 35-40 K and can be cooled with
inexpensive, off-the-shelf cryocoolers available from a number of manufacturers throughout the world. As will be
discussed, these advanced SuperMachines are attractive for use in industrial as well as naval and commercial
maritime industry applications. This paper discusses recent SuperMachine work at AMSC and other companies.
HTS rotating machine technology is maturing rapidly, and electricity producers as well as the end-users will
undoubtedly benefit enormously from these advancements.
