ABSTRACT:
A cooling arrangement for superconductive windings of electric machines is disclosed where the winding is held in a slot by means of a key. A distribution manifold is provided having distribution ducts adjacent to the key. The axially extending rotor slot is provided with upper and lower collecting ducts in its upper and lower portions respectively which are interconnected with a plurality of generally radially extending cooling ducts. The arrangement insures an efficient cooling with a comparatively simple design.
