Notes:
Rotary ultrasonic motors have found broad industrial application in camera lens drivesand other systems. Linear ultrasonic motors in contrast have only found limited applications. Themain reason for the limited range of application of these very attractive devices seems to be theirsmall force and power range. Attempts to build linear ultrasonic motors for high forces and highpower applications have not been truly successful yet. To achieve drives, larger force and higherpower, and multiple miniaturized motors can be combined. This approach, however, is not assimple as it appears at first glance. The electromechanical behavior of individual motors differsslightly due to manufacturing and assembly tolerances. Individual motor characteristics are stronglydependent on the driving parameters (frequency, voltage, temperature, pre-stress, etc.) and thedriven load and the collective behavior of the swarm of motors is not just the linear superposition ofthe individual drive’s forces
