Abstract: An electromechanical actuating drive, in particular a piezoelectric microstepper motor, has two piezoelectric bending transducers having in each case an effective direction not oriented parallel to one another. Said bending transducers act on a drive ring in order, via the latter, to rotate a shaft. The bending transducers are articulated via a sliding coupling or a shear-flexible structure, thereby minimizing mutual obstruction of the bending transducers during the displacement movement.
