Abstract

The electrodynamic inertial vibration exciter (1) for the excitement of an element (2) which is able to maintain and to transmit an input vibrational energy, includes a motor coil unit (3,4 ) with a winding (3) that is firmly attached to the pipe-like carcass element (4) of the coil, a magnet assembly (5, 6, 7) located concentrically in relation to the motor coil unit , the suspension device (11) by which the magnet assemble is fixed and which is able to make an axial movement relative to the motor coil unit, and a holder (9) which holds the motor coil unit (3, 4) and which is meant for the connection with the element (2) to be excited. The exciter has a connecting element (12) made to allow an interconnection with the magnet assembly (5, 6, 7), and the suspension device (11, 23, 24) is secured between the holder (9) and the connecting element (12).
