Superconducting wire and cad tool vendors combine forces to simplify electrical machine design
Zurück
The superconducting wire producer Sumitomo Electric, and the electromagnetic simulation expert Cobham Technical Services, have joined forces to offer an advanced solution for the design of electrical machines and power equipment.
Cobham's QUENCH electromagnetic software tool for modelling the quenching process in superconducting materials now comes with a library containing comprehensive manufacturer-supplied material characterisation data for Sumitomo's DI-BSSCO bismuth-based superconducting wire. The combination will greatly simplify the design and prototyping stages of applying high temperature superconductors (HTS). Among the application sectors currently exploring HTS-based solutions are electricity transmission and distribution infrastructure, hydroelectric and wind turbine generators, electric motor propulsion systems for ships, and high performance magnets.
"Design activity using HTS superconductors is growing very rapidly - driven by the maturing of HTS technology and the critical need to improve energy efficiency. This cooperation agreement provides an important means of simplifying and speeding design projects," says John Simkin of Cobham Technical Services. "It eliminates a major step in the design process of specifying the non-linear properties of the wire materials - which might involve testing under highly controlled operating conditions - allowing a designer to create an accurate model of an electrical component such as a coil simply by specifying the number of turns."
"Utilising this QUENCH electromagnetic software tool with DI-BSCCO data, many designers around the globe, who are not familiar with HTS wires until today, can more easily design and simulate their design. We hope this software will accelerate the HTS system developments that provide a benefit to our present and future society," says Kan Kinoshita of Sumitomo Electric.
