Claim Text:
1. An ultrasonic motor, comprising: a plurality of plate-shaped piezoelectric ultrasonic actuators, each having at least one friction element allocated thereto, wherein an element to be driven is assigned to each ultrasonic actuator or each of one or more pairs of ultrasonic actuators; a housing; and an electric excitation device, wherein the elements to be driven are movable independently of each other, and each ultrasonic actuator or each of the one or more pairs of ultrasonic actuators is arranged in a holder, wherein the holders are pressed against each other by means of housing side covers, and the friction elements on the ultrasonic actuators are pressed against a friction layer of the corresponding element to be driven by means of an elastic interlayer that is in contact with edge surfaces of the ultrasonic actuators that are arranged opposite the friction elements.
