Abstract
For improving the cooling of the rotor armature disk (2) of an electromagnetic retarder, connected to an outer flange (10) by a circle of arms (9) forming ventilation fins, these arms are formed by two parallel dividing walls (12) defining a narrow elongate pocket (13) whose bottom is formed by the disk and which opens axially into the free face of the flange through a slit (14) formed in this flange.
