Abstract: Disclosed is a multistage magnetic fluid sealing apparatus for superconducting rotating machines. According to the present invention, the magnetic fluid sealing apparatus, which is provided with a first magnetic fluid chamber and a second magnetic fluid chamber that are arranged in a multi-stage manner so as to contain a magnetic fluid capable of sealing the inner portion of a superconducting rotating machines, is installed on one surface of the superconducting rotating machines. The free magnetic fluid sealing apparatus of the invention configured to have a dual structure enables two to three fluid lines to be installed in the superconducting rotating machines.

Abstract: The present invention relates to superconducting rotating machines cooling apparatus using a heating pipe. According to the superconducting rotating machines, a shaft is fitted and coupled into a center of a central body, a stator yoke is coupled to the periphery of the central body, a superconducting coil is wound around a bobbin mounted on the stator yoke, and a cold head for cooling the superconducting coil is coupled to an end of the shaft. Also, in the superconducting rotating machines using the heating pipe, the heating pipe may be disposed on one surface from among all the surfaces of the bobbin around which the superconducting coil is wound or a winding portion of the superconducting coil so that the bobbin has a uniform temperature distribution therein.
