ABSTRACT:
A coupling device (11) between a rotor of a synchronous permanent-magnet motor and a working part (17), being advantageously able to ensure an unusual silentness, comprises a driving member (22), being eccentric with respect to the rotor rotation axis and integral with a first motion transmission component, and a driven element (24), being also eccentric with respect to the rotor rotation axis and integral with a second motion transmission component which is kinematically positioned in series with the previous one, said driving (22) and driven (24) members being placed on different non interfering parallel planes inside a tight chamber (18), said driving (22) and driven (24) members being operatively connected through kinematic connection means (25) whose axial dimension interferes with said parallel planes in said chamber (18), said kinematic connection means (25) comprising at least one elastic element (25a) being compressed in said chamber (18) between a bottom wall (19a) and a closing tight cover (19b).
