Abstract
The invention concerns an eddy-current retarder whose stator comprises a ring of electro-magnets mounted on a transverse common support 4, each electro-magnet comprising a core surrounded by a coil of wire 2. Each coil 2 is entirely enveloped in a case of hard insulating material moulded thereon and this case is wedged angularly on support 4 by cooperation of bosses 7 moulded therewith and notches 6 or other depressions hollowed out in support 4.
