ABSTRACT:
A contactless superconducting synchronous electrical machine comprises a rotor affixed to a rotatable shaft and provided with a superconducting field winding, the superconducting field winding being positioned within a cryostat; an annular stator located in concentrical relation with the rotor; and an exciter for the superconducting field winding provided with an inductor and a superconducting armature winding, the superconducting armature winding being positioned within the cryostat, affixed to the shaft and electrically connected to the superconducting field winding. The superconducting armature winding is implemented in the form of a cylindrical sheating affixed to a cylindrical surface of an annular former which is rigidly fixed to the shaft in concentrical relation therewith. The inductor comprises an immovable annular core with a multiphase winding, positioned in concentrical relation with the armature winding, and also comprises at least one magnetizing superconducting annular coil affixed to the shaft in axial relation to the former, in the vicinity of an end face thereof, and positioned within the cryostat. That portion of the vacuum shell of the cryostat which is within the gap between the annular core and the armature winding is made of dielectric material.
