Abstract

Dispositif ralentisseur à courants de Foucault pour véhicule, comprenant un stator 1 et un rotor 3. Le rotor comprend deux disques 3a et 3b défilant devant des bobines d'induction 6 alternativement de polarité opposée portées par le stator. Les bobines sont portées par des plaques 9 alternativement situées de chaque côté du stator, de manière que le stator soit porté à une polarité uniforme, évitant les courts-circuits magnétiques. Application à tous les ralentisseurs à courants de Foucault.
