Abstract
A microstepper motor which comprises two electromechanical drive elements, especially piezoelectric bending actuators, having effective directions that are perpendicular to each other. These actuators act upon a drive ring to thereby rotate a shaft. The actuators are non-radially hinged to the drive ring via an approximately square shear-flexible and torsion-proof frame structure, the drive ring being arranged inside said frame. The drive according to the invention is compact, the frame and the drive ring being configured as a single injection-molded drive module.
