Abstract
This concerns a rotor armature of an electromagnetic retarder, comprising at least one disk (2) axially prolonged over one of its faces by a plurality of fins (9), each fin being delimited by two faces which are parallel or substantially so, and are inclined with the corresponding radii, the tips of these fins being connected together by an annular flange (11) and the assembly of the disk, of the fins and of the flange being formed all in one piece molded from a ferromagnetic material. This rotor comprises, between the disk (2) and the flange (11), between the fins (9) molded in one piece with the disk and the flange, a plurality of thermally conductive independent inserts (13) extending parallel to the axis of the rotor and whose axial end edges (15) are embedded to a small depth in respectively the two mutually opposite transverse faces of the disk and the flange.
