A superconducting DC machine includes a superconductive field winding housed in a cryostat. A magnetic shield is arranged outside the cryostat. An armature drum is rotatably supported between the cryostat and the magnetic shield. The armature drum of the machine is divided into a plurality of segments along the length thereof, and has arranged thereon current-collecting brushes not more than one half of the segments. Each brush is electrically connected to the opposed one at the other longitudinal end of the same segment of the armature drum and also to the one at the longitudinal opposed end of an adjacent segment in diagonal fashion progressively.
