<p>The device i.e. balancing device (10), has a balancing mass (12), and a drive unit for adjusting the mass. The unit has an electromechanical oscillating drive with an electrical excitation device (30). An oscillator (24) is excited to an oscillating movement by the excitation device, and a conversion device (36) converts the oscillating movement of the oscillator into an aligned adjustable movement of the mass. The excitation device has electromagnets (32), and the oscillator is made from magnetic or magnetisable material, where the oscillator is arranged between the electromagnets.</p> |
