Abstract
A motor which includes two 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. Diagonally opposite securing elements are provided on the drive ring and are used to flexibly suspend the drive ring via respective articulated corner elements on respective fixing elements that are diagonally opposite the respective securing elements. The drive according to the invention is compact, having actuators that are non-radially hinged to the drive ring.
