ABSTRACT:
An electric retarder is provided for braking the transmission shaft (A) of a vehicle, in which the stator comprises at least one ring of coils (1) supported by a transverse plate (2) itself stiffened by a rib. The portion (7) of the stiffening rib of the plate, situated at the level of the axis (X) of the retarder, is disposed inside the ring of coils and is connected by radial extensions (10) each passing between two consecutive coils to outer rib sections (8,9) extending as far as the periphery of the plate. Thus the overall width L.sub.2 of the stator may be reduced for a given width l of the ring of coils, which makes standardization of the manufacture of the rotors possible in some cases.
