Abstract

The invention relates to a force module (20) for generating forces in a highly dynamic manner by assembling a plurality of piezo actuators (1) for connecting to a voltage source. To enable the force module (20) to generate forces in the range of a few 100 kN in a highly dynamic and spatially resolved manner, according to the invention it is proposed that the force module (20) consists of at least two sub-modules (21), each having at least two piezo actuators (1) and their electrical contacting elements, and a controlling and protection module (16) for the piezo actuators (1) in the sub-modules (21), wherein all electric contacting elements of the sub-modules (21) are fed into the controlling and protection module (16).
