Electric damper assembly
Abstract:
An electric damper assembly includes a damper having a rotor and a stator which connect a first component and a second component movable relative thereto, excitation windings, and induction windings, wherein a rotation of the rotor in relation to the stator causes a rotation of the excitation windings relative to induction windings, thereby inducing an induction voltage in the induction windings. A sensor detects the movement of the first component relative to the second component. A control unit is connected to the sensor and the damper. The control unit supplies the excitation winding with electric energy in such a way that an electromagnetic rotary field is generated which is dependent on the detected movement, and thereby is superimposed on the rotation of the rotor relative to the stator.
