A plurality of longitudinal channels (8) which are distributed uniformly over the circumference, are continuous and have an undercut cross-section which is open to the exterior are provided in the cage-type armature (10), in the vicinity of the outer circumference. Conductors (9) which completely fill the longitudinal channels (8) are arranged in said longitudinal channels (8) so that the balance state does not change at high speeds and the centre of gravity of the current path is located well to the exterior so that the moment arm and thus the torque are increased. The filling is carried out by a conductor profile, which is pushed in along the length from the end, being forced, for example hammered or rolled, into the longitudinal channels radially from the outside. <IMAGE>
