Abstract

Die vorliegende Erfindung offenbart einen elektromechanischen Motor, insbesondere einen piezoelektrischen Ringmotor, während der Antriebsring (20) des Ringmotors durch piezoelektrische Vielschichtaktoren (10) zu einer Verschiebebewegung angeregt wird. Die piezoelektrischen Vielschichtaktoren werden durch Vorspannelemente (40) vorgespannt, die sich parallel zur Wirkrichtung (12) des piezoelektrischen Vielschichtaktors (10) sowie über den piezoelektrischen Vielschichtaktor (10) hinaus und zumindest teilweise über den Antriebsring (20) erstrecken.
