  1. 370. [Invited] Development of Superconducting PM Machines
    Mitsuru Izumi (TOKYO UNIVERSITY OF MARINE SCIENCE AND TECHNOLOGY (TUMSAT))
    11/07/2017, 11:00
    Invited Oral Presentation

    High-temperature superconducting (HTS) materials offer a mature core-technology for propulsion motor/generators in transportation. In Japan, 1-3 MW synchronous motors for ship propulsion have been developed by industry-national institute-academia liaison using HTS wires. As alternative choice for field poles, melt-growth bulk HTS provides a successful design and making of prototype modules for...

  2. 518. AC Loss Analysis in Fully Superconducting Machines
    Mr Matthew Feddersen (University of Illinois, Urbana-Champaign)
    11/07/2017, 11:30
    Contributed Oral Presentation

    Superconducting electric machines have shown potential for dramatic increases in power density for applications such as offshore wind generation, marine propulsion, and turbo-electric distributed aircraft propulsion. Superconductors exhibit zero loss when in dc conditions, though ac current produces considerable loss due to hysteresis, eddy currents, and coupling. For this reason, many present...

  3. 553. Present Status of Turbo-Brayton Cycle Cooling System in Japan
    Hirokazu Hirai (Taiyo Nippon Sanso Corporation)
    11/07/2017, 11:45
    Contributed Oral Presentation

    High temperature superconductive (HTS) power machines, such as a power cable, a transformer and a fault current limiter, have been tried to approach commercialization recently. In commercializing of HTS power machines, a cooling system shall have cooling capacity from 2kW to 10kW at 70 K, long maintenance interval and high efficiency (low input power). The HTS power machines are cooled by...

  4. 574. Updated Survey of Cryogenic Cooling Technologies for Superconducting Power Systems
    Michael Susner (Air Force Research Laboratory)
    11/07/2017, 12:00
    Contributed Oral Presentation

    As useful applications for superconductors continue to expand, required cooling methods still tend to be custom tailored for each application. The performance, capabilities, and economies of varying cryogenic cooling options are therefore an important concern for machine designers and end users. Features that are critical in the initial design and must be included in trade-offs when...

  5. 605. Overview of Cooling Technologies for Cryogenic Transportation Machines
    Wolfgang Stautner (GE Global Research), Timothy Haugan (U.S. Air Force Research Laboratory)
    11/07/2017, 12:15
    Oral Presentation

    The authors give an overview of cooling technologies for cryogenic transportation machines that are most promising, followed by a brief survey and analysis in which way commercially available cryocoolers could be applicable.
