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 a torsion-proof, nested frame-type complex structure (drive module) including an interior drive ring, a frame and a U-shaped outer frame. The drive according to the invention is compact and, the drive module being is configured as a single injection-molded structure.
