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. Two tension-compression bars, which are parallel to an effective direction, are connected to the drive ring, have respective joints at their ends and are connected to the ends of a diagonal bar, relative to which the ring can be displaced in the other effective direction. The diagonal bar itself can be displaced relative to fixing elements to an effective direction via a diagonal suspension. The drive is compact, having actuators that are non-radially hinged to the ring.
