  • Superconducting synchronous machine
    Patent number: 8204562
    Abstract: Disclosed herein is a superconducting field coil of a homopolar type superconducting synchronous machine. The superconducting synchronous machine includes a superconducting field coil which comprises a single or double pancake coil formed by winding a superconducting wire, a core-type rotor which is made of a magnetic material, and an armature winding excited to three phases on a surface of a core of a stator. The field coil of the homopolar type superconducting synchronous machine is not rotated when the machine is in operation. Thus, there is no part for coupling the rotating field coil to a stationary cryo-cooler for cooling a refrigerant, so that the structure is simple, reliability is high, and various cooling methods are available.
    Type: Grant
    Filed: December 9, 2008
    Date of Patent: June 19, 2012
    Assignee: Korea Electrotechnology Research Institute
    Inventors: Young Kil Kwon, Ho Min Kim, Seung Kyu Baik, Eon Young Lee, Jae Deuk Lee, Sang Ho Lee, Yeong Chun Kim, Young Sik Jo, Gang Sik Ryu
