ABSTRACT:
A contactless synchronous electric machine comprises a stator carrying an armature winding, a field winding and a rotor with claw-shaped pole systems coaxially surrounding the stator with the armature winding. The armature winding and the field winding are made from a superconducting material and secured within a cryostat with liquid helium blowing round said windings. The cryostat is axially disposed within the rotor and is attached to a housing. The assembly including the rotor, cryostat and stator is vertically arranged in the housing and the rotor shaft extends through an opening in the bottom of the housing.
