Abstract: Electromagnetic damper (1) for rotating machines (100) having at least a stator (103) and a rotating shaft (100); the electromagnetic damper (1) is able to damper the vibrations of the rotating machine (100) during its functioning. The damper includes windings (2) of electrically conducting material, for generating a magnetic field; a magnetic circuit (4), for conveying within it a magnetic flux generated by the windings (2); a power supply (8), for supplying the windings (2) of electrically conducting material; the power supply (8) of the electromagnetic damper (1) is positioned inside the rotating machine (100).

Abstract: Automatic control device (30) (30?) (30?) for an electromagnetic damper of vibrations (50) having windings (51) arranged around a rotor (62) of a rotating machine (60) and supplied by an electric signal; the electromagnetic damper of vibrations also having a magnetic circuit (54), constituted by a first part (54a) and a second part (54b) separated between them by an air gap (54c). The automatic control device (30) (30?) (30?) includes: amplification stages (32) (32?) (32?) for supplying the windings (51) and having at least an output (32a) (32?a) (32?a); signal processing stages (31) (31?) (31?) electrically connected to the amplification stages (32) (32?) (32?). The signal processing stages (31) supply the amplification stages (32) (32?) (32?) on the basis of an electric signal (a(t)) of voltage and/or current drawn on at least one output (32a) (32?a) (32?a); by one or more sensible elements (34) remote in comparison with the rotor (62) and variable as an inductance of the windings (51) varies.
