DYNAMIC FORCE GENERATOR COMPRISING AT LEAST TWO UNBALANCED MASSES AND ACTUATOR COMPRISING SAID GENERATORS

The invention relates to a dynamic force generator (100) comprising - a supporting shaft (110); - a first rotor (120) comprising: an internal bore (121) housing said supporting shaft (110) and bearings (R1, R2) arranged between the supporting shaft (110) and the internal bore (121) so that the first rotor (120) is mounted rotatably in relation to said supporting shaft (110), an external bore (122) comprising an inner face (FIE1) provided with a first set of permanent magnets (180), a connecting zone (123) between the internal bore (121) and the external bore (122) of the first rotor, said connecting zone (123) moreover being intended to house an electrical coil able to interact with the first set of permanent magnets in order to constitute an electric motor for the first rotor (120), a first unbalanced mass (130) fixed to or formed integrally with the internal bore (121) of the first rotor (120) and mounted opposite an outer face (FEE1) of the external bore (122) of the first rotor; - a second rotor (140) mounted rotatably in relation to the first rotor (120), via an antifriction component (160) provided between the first rotor (120) and the second rotor (140), this second rotor (140) comprising: an internal bore (141) housing the internal bore (121) of the first rotor (120), so that said internal bores (121, 141) of the first and second rotors (120, 140) are concentric, an external bore (142) comprising an inner face (FIE2) provided with a second set of permanent magnets (181), a connecting zone (143) between the internal bore (141) and the external bore (142) of the second rotor, said connecting zone (143) being intended to house an electrical coil able to interact with the second set of permanent magnets (181) in order to constitute an electric motor for the second rotor; and a second unbalanced mass (150) fixed to or formed integrally with the internal bore (141) of the second rotor (140) and mounted opposite an outer face (FEE2) of the external bore (142) of the second rotor (140). La présente invention concerne un générateur de force dynamique (100) comprenant - un arbre de support (110) ; - un premier rotor (120) comprenant : un alésage interne (121) logeant ledit arbre de support (110) et des paliers (R1, R2) disposés entre l'arbre de support (110) et l'alésage interne (121) de sorte que le premier rotor (120) soit monté en rotation par rapport audit arbre de support (110), un alésage externe (122) comprenant une face interne (FIE1) dotée d'un prem
