ABSTRACT:
The active vibration-absorber is, in particular, an engine mount for motor vehicles. A magnet system has a magnet casing which receives a permanent magnet and which is guided in the assembly so as to be capable of movement in the axial direction. An electrical moving coil projects perpendicularly from a carrier plate and moves into the magnet casing. The carrier plate can be connected to a vibrating machine part, such as between the engine and the vehicle frame. The magnet system is held, in the axial direction, by a magnetic leakage field which is present between the magnet system and stationary ferromagnet.
