Rotating Machines

Leveraging superconductivity’s high power density and enhanced electrical efficiency, rotating machines that incorporate AMSC’s HTS wire can be as little as one-third the weight and half the size of comparably powered traditional alternatives. Reducing their size and weight frees valuable real estate that often can be turned into additional revenue generation.

HTS motors and generators deliver higher net efficiency at all load conditions, with their advantage over conventional machines being even greater at partial load conditions, because they experience no resistive losses in the rotor.  HTS rotating machines typically exhibit as little as half the electrical losses of a conventional machine when at full power.

Application areas for this technology include:

HTS Ship Propulsion Motors, enabling ships to carry larger freight or passenger payloads at a reduced operating cost, measurably boosting profits as a consequence.

• Compact and lightweight form factor increases flexibility in ship design.

• Energy efficient for decreased fuel consumption.

HTS Utility Generators, offer higher efficiencies than conventional machines over their full range of operation while delivering lower lifetime costs, in part due to their:

• Enhanced reliability and improved MTBF because they operate at a constant temperature, eliminating the heat-expansion and mechanical fatigue associated with thermal cycling.

• Reduced lifetime ownership costs, based on efficiencies in, on recovered fuel costs alone, would provide a payback period for the full acquisition cost of the machine recover within a few years of operation, as well as additional cost benefits from improved efficiencies at partial load.
