The invention relates to a device for generating a torque on an output member (3) in response to a torque setpoint, comprising: a first driving member comprising at least one motor (1) with a first power, or small motor, with a shaft (2) onto which the output member is connected; a second driving member including at least one motor (11) having a second power higher than the first power, or large motor, with a shaft (12) rotatingly connected to the output member via viscous coupling means (4); driving means (50) programmed for powering the second driving member (11) in response to a torque setpoint (Mcons) so that the viscous coupling means provide a viscous torque (Mvisq) corresponding to the torque setpoint and, in parallel, to power the first driving member (1) so that it provides the additional torque between the torque setpoint and the viscous torque during the time necessary for the viscous torque to reach the value of torque setpoint.
L' invention est relative à un dispositif pour générer un couple sur un organe de sortie (3) en réponse à une consigne de couple, comportant :- un premier organe moteur comportant au moins un moteur (1) d'une première puissance, ou petit moteur, ayant un arbre (2) sur lequel l'organe de sortie est connecté; - un deuxième organe moteur comportant au moins un moteur (11) d'une deuxième puissance plus importante que la première puissance, ou gros moteur, ayant un arbre (12) relié en rotation à l'organe de sortie via des moyens d'accouplement visqueux (4); des moyens d'asservissement (50) programmés pour, en réponse à une consigne de couple (M cons), alimenter le deuxième organe moteur (11) pour que les moyens d'accouplement visqueux fournissent un couple visqueux (M visq) répondant à la consigne de couple, et, en parallèle, alimenter le premier organe moteur (1) pour qu' il fournisse le complément de couple entre la consigne de couple et le couple visqueux, le temps que le couple visqueux atteigne la valeur de la consigne de couple.
