The relative speed control is provided by two coaxial bodies (1,2) each in cooperation with one the two moving parts. The coaxial bodies are coupled one to the other so they can rotate about a common axis (5). An electromagnetic damper (3) is fitted between the two coaxial bodies and is formed by an eddy current brake (31,32). The damper operates through a speed multiplier formed by epicyclic gear trains, which incorporate a torque limiting spring (12) or a friction cone.
