  1. 911. M2Or4A-01 [Invited]: Bulk Superconductors for Motors – Practical Materials Challenges
    Dr John Durrell (University of Cambridge)
    23/07/2019, 17:15
    Invited Oral Presentation

    For those versed in superconductivity, flux pinning and critical current are the keys to improving performance in practical applications. When considering the practical deployment of bulk superconductors in rotating machines, however, the range of practical challenges to deployment is considerably enlarged. In this contribution we describe progress made in an ongoing collaboration between...

    Invited Oral Presentation

    There is worldwide interest for high-speed motors and generators with characteristics of compactness, lightweight and high efficiency for aerospace applications. Several options are under consideration. However, machines employing High Temperature Superconductor (HTS) look promising for enabling machines with the desired characteristics. The machines employing excitation field windings on the...

  3. 1103. M2Or4A-03 [Invited]: Coolant Transfer Coupling for a Rotor Carrying HTS Windings
    Swarn Kalsi (Retired)
    23/07/2019, 18:15
    Invited Oral Presentation

    Superconducting synchronous machines mostly employ HTS field excitation windings on the rotor operating at cryogenic temperature. These windings are usually cooled by coolant supplied from a stationary source to the rotor with rotary couplings. Closed loop gaseous helium couplings have been employed on mega-watt size machines operating at both low speed and high speed. However, these...
