ABSTRACT:
An alternating current generator of the kind having a superconductive direct current field winding wherein: the field winding is carried on the stator; the armature winding is carried on the rotor; shaft and current collection from the armature winding is effected via a liquid metal slip-ring arrangement. The invention also provides a liquid metal slip-ring arrangement, for use with dynamo electric machines, comprising a first annular member which rotates with the machine rotor, and a non-rotating second annular member which is electrically connected to the first annular member via the liquid metal of the slip-ring arrangement, and arranged to move axially with the first annular member during axial movement of the rotor.
